Description

Technical Field

[0001] The invention relates to the technical field of welding, and in particular to a welding auxiliary tooling for a deposited metal test plate and a use method thereof. Background Art

[0002] In order to test whether the welding performance, physical and chemical properties of welds, corrosion resistance and other indicators of welding materials meet the standard requirements, prevent unqualified welding materials from entering the welding production process, ensure the welding quality of welding products, or test the relevant indicators and performance of newly developed welding materials, it is often necessary to conduct deposited metal tests on welding materials according to the relevant standards of materials and welding specifications. Since the deposited metal test plate is a V-shaped groove node, its transverse (perpendicular to the length of the weld) welding shrinkage is asymmetric shrinkage, which will produce an upward deformation trend during welding, and it is easy to produce upward angular deformation after welding. Excessive angular deformation will affect the subsequent mechanical sampling and related mechanical property tests of the test plate. Therefore, measures need to be taken to prevent the angular deformation of the test plate and ensure that the test plate is flat after welding.

[0003] like Figure 1 As shown, in the prior art, the deposited metal test plate 100' includes a gasket 110' and two welding plates 120' with processed welding grooves (inclined surfaces). The two welding plates 120' are fixed on the gasket 110' after adjusting the assembly gap at the root of the groove to form the test plate 100'. The two welding grooves form a V-shaped groove 130' node on one side of the test plate 100'. Two temporary fixing clamps 200' are welded and fixed on the other side of the welding plate 120'. Each temporary fixing clamp 200' is welded on the two welding plates 120' at the same time to constrain the welding plate 120' and prevent the welding plate 120' from warping upward and causing excessive angular deformation during the welding process of the V-shaped groove 130'. After welding, the temporary fixing code 200' is removed by thermal cutting, and the code foot left after the temporary fixing code 200' is removed from the surface of the test plate 100' is ground flat. Finally, non-destructive testing and related physical and chemical tests are performed on the test plate 100'.

[0004] However, the temporary fixed card code 200' needs to be welded on the test plate 100', and after use, it needs to be removed by thermal cutting, the code foot grinding and other operations, which requires many construction processes, large workload, time-consuming and labor-intensive. After the temporary fixed card code 200' is removed, the surface quality of the test plate 100' is reduced. The temporary fixed card code 200' can only be used once, resulting in material waste. In addition, after each weld is completed, a handheld temperature measuring device is required to measure the temperature of the welding plates 120' on both sides of the weld. The next weld can only be welded after reaching the specified temperature, which is inconvenient to operate. Summary of the invention

DETAILED DESCRIPTION

[0046] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0047] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0048] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0049] like Figure 2-Figure 9 As shown, the test plate 100 includes a gasket 110 and two welding plates 120 fixed to the gasket 110 . The welding plates 120 have inclined surfaces 121 . The inclined surfaces 121 of the two welding plates 120 form a V-shaped groove 130 . The present embodiment provides a welding auxiliary tooling for a deposited metal test plate. The welding auxiliary tooling 200 includes a base plate 210, a rib plate 220, a temperature monitoring system 230, two crimping parts 240 and two gate-shaped frames 250. The rib plate 220 and the two frames 250 are both arranged on the base plate 210. The rib plate 220 is located between the two frames 250. The two crimping parts 240 are correspondingly arranged on the two frames 250. The test plate 100 can pass through one frame 250 so that the pad 110 is supported on the rib plate 220. The two crimping parts 240 are correspondingly crimped on the side of the two welding plates 120 away from the pad 110. The temperature monitoring system 230 is used to detect the temperature. When the temperature is outside the preset range, a first prompt signal is issued, and when the temperature is within the preset range, a second prompt signal is issued.

[0050] The rib plate 220 and the crimping piece 240 are used to clamp the test plate 100, and the assembled test plate 100 is rigidly fixed in a non-welding fixing mode. The welding process of the test plate 100 is completed under the rigid fixing constraint condition. The two crimping pieces 240 correspondingly crimp the two welding plates 120, and the lateral (perpendicular to the length direction of the weld) angular deformation of the test plate 100 has a good restraining effect, preventing the upward angular deformation after welding, ensuring the flatness after welding, and ensuring the accuracy of the test data. Compared with the prior art using temporary fixed card codes, the welding auxiliary tooling 200 of this scheme can be reused to avoid material waste; there is no need for welding, thermal cutting and removal, code foot grinding and other operations, which reduces the construction process, reduces the workload, saves time and effort, is convenient to operate, and is highly efficient, and avoids the influence of the removal of the temporary fixed card code on the surface quality of the welding plate 120, and the surface quality of the welding plate 120 is better.

[0051] In the related art, the welding method required by the cladding test is: after each weld is completed, a handheld temperature measuring device is required to frequently measure the temperature of the welding plates 120 on both sides of the weld, and the next weld is welded after reaching the specified temperature range. The timing of manual temperature measurement is not accurately controlled, and the number of manual temperature measurements is large. If the temperature measurement lag causes the temperature of the test plate 100 to be lower than the specified lower limit, measures need to be taken to heat the welded test plate 100, and the process is complicated and inefficient. This solution can use the temperature monitoring system 230 to detect the temperature. When the first prompt signal is issued, it is outside the preset range, and measures need to be taken before welding. When the second prompt signal is issued, it is within the preset range, and welding can continue. By adopting the temperature monitoring system 230, it is possible to continuously measure the temperature and issue prompt signals, control the timing of temperature measurement, effectively avoid unnecessary heating processes, improve construction efficiency, and ensure welding effects, avoid manual operation, and operate conveniently.

[0052] The crimping member 240 includes at least two fasteners, at least two fasteners are arranged along the first direction and connected to the top of the frame 250, the bottom of the fasteners abuts against the welding plate 120, the two welding plates 120 are arranged along the second direction, and the first direction and the second direction are arranged at an angle. Exemplarily, the gate-shaped frame 250 includes a crossbeam 252 and two column legs 253, the fastener is a bolt, a threaded hole 251 is provided on the crossbeam 252, and the bolt is threadedly connected to the threaded hole 251. When the test plate 100 is placed in front of the welding auxiliary fixture 200, the bolt is screwed upward to increase the bottom space, so that the test plate 100 can pass through the gate-shaped frame 250 and be placed on the welding auxiliary fixture 200. Afterwards, the bolt is screwed downward to crimp the bottom of the bolt on the welding plate 120. The structure is simple, the operation is convenient, and the crimping of the test plate 100 is stable and reliable. For example, three threaded holes 251 are provided along the extension direction of the crossbeam 252, i.e., the first direction, and three bolts are installed in the three threaded holes 251 in a one-to-one correspondence, which has a good restraining effect on the longitudinal (weld length direction) bending deformation of the test plate 100. That is, the welding auxiliary fixture 200 has a good restraining effect on both the transverse and longitudinal deformations of the test plate 100, and the deformation of the welded test plate 100 after welding is small, ensuring the flatness after welding and the accuracy of the test data.

[0053] The temperature monitoring system 230 includes a support frame 231, a temperature measuring element 232 and an alarm 233. The support frame 231 is arranged on a frame 250. The temperature measuring element 232 and the alarm 233 are both arranged on the support frame 231. The temperature measuring element 232 and the alarm 233 are connected in communication. The temperature measuring element 232 is used to measure the temperature. When the temperature is outside the preset range, the alarm 233 sends a first prompt signal. When the temperature is within the preset range, the alarm 233 sends a second prompt signal. Specifically, the temperature measuring element 232 is a contact temperature sensor, which continuously detects the temperature of the test plate 100 and the alarm 233 continuously sends a prompt signal. Exemplarily, the temperature monitoring system 230 also includes a monitoring component 234, which is connected in communication with the temperature measuring element 232 and the alarm 233 respectively. The temperature measuring element 232 feeds back temperature information to the monitoring component 234, and the monitoring component 234 sends a control signal to the alarm 233, so that it sends the first prompt signal or the second prompt signal. Furthermore, the alarm 233 is an audible and visual alarm. For example, when the temperature exceeds the preset temperature upper limit or lower limit, the alarm 233 will send out an alarm sound signal and a red flash signal; when the temperature reaches the preset range, that is, the temperature upper limit to the lower limit interval, the alarm 233 will stop the alarm sound signal and the red flash signal, and send out a green signal at the same time. The first prompt signal and the second prompt signal are both a combination of an audible alarm signal and a visual alarm signal, and it is more intuitive to judge the instantaneous temperature of the test plate 100 by sight or hearing.

[0054] The temperature monitoring system 230 also includes a display, which is connected to the temperature measuring element 232 for displaying the temperature value. The current temperature can be intuitively understood through the display to distinguish whether the temperature of the test board 100 is too high or too low when the alarm 233 sends the first prompt signal.

[0055] The support frame 231 includes a vertical rod 2311, a horizontal rod 2312, a sleeve 2313 and a locking piece 2314. The monitoring component 234, the temperature measuring piece 232 and the alarm 233 are all installed on the horizontal rod 2312. The horizontal rod 2312 is connected to the outer periphery of the sleeve 2313. The sleeve 2313 is sleeved on the vertical rod 2311. The vertical rod 2311 is fixed to a frame 250. The sleeve 2313 can be slidably and rotatably connected to the vertical rod 2311. The locking piece 2314 can lock the sleeve 2313 to the vertical rod 2311. When the locking piece 2314 is unlocked, the temperature measuring piece 232 and the alarm 233 can be lifted and lowered along the vertical rod 2311 or freely rotated around the vertical rod 2311 along with the horizontal rod 2312, so as to arbitrarily adjust the position of the temperature measuring piece 232 for temperature measurement, increase the measurement range, and improve applicability. Exemplarily, the sleeve 2313 is provided with a through hole, and the locking piece 2314 is a bolt, which passes through the through hole and has its end abutted against the vertical rod 2311, so that the positions of the sleeve 2313 and the vertical rod 2311 are relatively fixed, that is, the cross bar 2312 and the vertical rod 2311 are locked, with a simple structure and convenient operation.

[0056] like Figure 2-Figure 11 As shown, this embodiment also provides a method for using a welding auxiliary tooling for a deposited metal test plate, comprising the following steps:

[0057] S100, assembling a test board 100, or using a prefabricated test board 100;

[0058] S200, pass the test plate 100 through the frame 250, the gasket 110 is supported on the rib plate 220, and the two crimping parts 240 are correspondingly crimped on the two welding plates 120, which is easy to operate. Specifically, the longitudinal center line of the gasket 110 is consistent with the longitudinal center line of the rib plate 220. When the crimping part 240 is a bolt, after the test plate 100 is placed in the welding auxiliary tooling 200 and the position is adjusted, all the bolts are installed and tightened in sequence, so that the lower end faces of the fixing bolts are fully in contact with the upper surface of the welding test plate 100, to achieve effective rigid constraint fixation of the welding test plate 100, to prevent it from warping upward during the welding process, and to ensure its flatness after welding.

[0059] S300, welding the V-shaped groove 130 by using the welding method required by the deposition test, and welding a weld on the V-shaped groove 130;

[0060] S400, using the temperature monitoring system 230 to perform a temperature test on the test board 100;

[0061] S500, when the temperature monitoring system 230 sends out a second prompt signal, the above step S300 is looped to perform the next weld on the V-shaped groove 130 using the welding method required by the cladding test, to ensure that the welding temperature meets the test requirements and improve the accuracy of the test data.

[0062] The test plate 100 includes a gasket 110 and two welding plates 120, and the gasket 110 is made of steel; the welding auxiliary tooling 200 also includes: an assembly platform 260, an assembly clamping plate 270 and two adjustment pads 280; in step S100, that is, when the two welding plates 120 are fixed to the gasket 110, the use method also includes:

[0063] S110 , placing the gasket 110 and two adjusting pads 280 on the assembly platform 260 ; the two adjusting pads 280 are placed parallel to the gasket 110 .

[0064] S120, place the assembly card plate 270 on the upper surface of the gasket 110, and the two welding plates 120 are correspondingly arranged on the adjustment pad 280, and the ends of the welding plates 120 are flush with the ends of the gasket 110 and the adjustment pad 280. The two welding plates 120 are correspondingly abutted against the two sides of the assembly card plate 270, so that the width of the assembly card plate 270 is consistent with the gap at the root of the groove of the V-shaped groove 130; the assembly card plate 270 plays a limiting role, and the width of the assembly card plate 270 is consistent with the required gap at the root of the welding groove, so as to avoid the measurement and adjustment of the two welding plates 120 by naked eye, resulting in the gap size of the V-shaped groove 130 not meeting the requirements, and avoid displacement of the welding plate 120 in the subsequent welding process, which affects the welding filling cross-sectional area and welding heat input, and causes distortion of the cladding test result data.

[0065] S130, using the welding method required by the cladding test, tack weld the ends of the welding plate 120 and the gasket 110 to form the test plate 100, and weld between the welding plate 120 and the gasket 110 to form a tack weld 140; specifically, welding is performed at the ends of the gasket 110 and the welding plate 120, and at the positions on the sides of the two welding plates 120 facing each other. The tack weld is a single-pass weld, and the tack weld length is 10 mm-15 mm.

[0066] S140 , taking out the assembly card plate 270 .

[0067] Optionally, two spaced assembly pallets 270 are used, the length of the assembly pallet 270 is about 50 mm to 60 mm, and the height is greater than the thickness of the welding plate 120, so as to facilitate subsequent removal. The longitudinal center line of the assembly pallet 270 is consistent with the longitudinal center line of the gasket 110, and the two assembly pallets 270 are 30 mm to 50 mm away from the ends of the respective adjacent test plates 100, so as to reserve space for positioning welding. Optionally, the thickness of the adjustment pad 280 is the same as the thickness of the gasket 110 to ensure that the upper surfaces of the two welding plates 120 are flush.

[0068] Further, the temperature monitoring system 230 includes a support frame 231, a temperature measuring element 232 and an alarm 233. The support frame 231 includes a vertical rod 2311, a horizontal rod 2312, a sleeve 2313 and a locking element 2314. The support frame 231 is arranged on a frame 250, and is exemplarily installed on a column leg 253. When the locking element 2314 is unlocked, the temperature measuring element 232 and the alarm 233 can be lifted and lowered along the vertical rod 2311 or rotated freely around the vertical rod 2311 along with the horizontal rod 2312. When the temperature monitoring system 230 is used to perform a temperature test on the test plate 100 in step S400, it includes:

[0069] S410, the locking member 2314 is unlocked, so that the horizontal rod 2312 moves downward relative to the vertical rod 2311 and rotates to the measuring position, and the temperature monitoring system 230 is used to perform a temperature test on the test plate 100; the temperature measuring position of the temperature measuring member 232 is adjusted according to the position of the test plate 100 to ensure measurement accuracy.

[0070] S420, when the temperature monitoring system 230 sends out the second prompt signal, the horizontal rod 2312 is moved upward relative to the vertical rod 2311 and rotated in the opposite direction to the initial position to prevent structural interference during welding.

[0071] The temperature monitoring system 230 also includes a display, and after step S400, the following steps are further included:

[0072] S600, when the temperature monitoring system 230 sends out the first prompt signal, check whether the temperature value displayed on the display is higher than the preset range; if so, that is, when the temperature value is higher than the preset range, execute S601; if not, that is, when the temperature value is lower than the preset range, execute S602;

[0073] S601, cool the test plate 100 or continue to wait for natural cooling until its temperature reaches the preset range, that is, until the temperature monitoring system 230 sends out a second prompt signal; since the temperature measuring component 232 has been continuously detecting the temperature of the test plate 100, when it has not reached the preset range, it continues to cool until it reaches the preset range, the temperature monitoring system 230 sends out a second prompt signal, and the next step of welding can be carried out.

[0074] S602 , heating the test board 100 until its temperature reaches a preset range, that is, until the temperature monitoring system 230 sends a second prompt signal.

[0075] According to the requirements of the relevant technical standards of the cladding test, the parameters of the contact temperature measurement and alarm system are preset, and the upper and lower limits of the temperature are set, such as the upper limit is 250°C and the lower limit is 100°C. After welding a weld, loosen the locking piece 2314 of the temperature measurement system, i.e., the bolt, rotate the crossbeam 252, so that the end of the temperature measurement probe of the contact sensor reaches the middle of the test plate 100 (the side of the weld, 10mm-20mm away from the edge of the weld), and fully contacts the surface of the test plate 100. Turn on the alarm 233 switch to start the automatic temperature measurement and alarm mode. When the temperature exceeds the preset upper temperature limit, the alarm 233 will send an alarm sound signal and a red flash signal, and synchronously display the instantaneous temperature. At this time, the test plate 100 is in a high temperature stage and cannot be welded. The welder can rest and wait without manual temperature measurement. When the temperature reaches the preset temperature upper limit to lower limit range, the alarm 233 will stop the alarm sound signal and the red flash signal, and send a green signal at the same time, and synchronously display the instantaneous temperature. At this time, the test plate 100 is in a weldable stage, and the welder is ready to weld. When the temperature is lower than the preset lower limit, the alarm 233 will emit an alarm sound signal and a red flash signal, and synchronously display the instantaneous temperature. At this time, the test board 100 is in a low temperature stage and cannot be welded. The test board 100 needs to be heated to between the upper and lower limit temperatures before welding can continue. This method is used until the test board 100 is welded.

[0076] After welding is completed, the following steps are also included:

[0077] S700, the test plate 100 is naturally cooled in the welding auxiliary fixture 200, and after being placed for 24 hours, the welding stress is effectively released, and then all the fixing bolts, i.e., the crimping parts 240, are loosened, and the test plate 100 is taken out from the side of the welding auxiliary fixture 200 through the frame 250, and the welding of the test plate 100 of the first cladding test is completed. The welding auxiliary fixture 200 can be used for the next test plate 100 fixing and welding, and can be reused many times.
