Embodiment 1

[0046] Such as Figure 1~12 Shown, a kind of weldment seam full-penetration welding device, the first welding base metal 5 and the second welding base metal 6 weld seam side are provided with liner 12, liner 12 and first welding base material 5 and The second welding base material 6 is in contact with the weld seam. The preferred circular ceramic pad in this program is placed on one side of the first welding base material 5 and the second welding base material 6 welds, such as Figure 4-5 The shown structure reduces the work of cleaning the root of the weld seam on the other side of the weld seam, makes the welding steps on the other side simpler, and does not need to perform effective root cleaning work on the other side.

[0047] Also be provided with welding base plate 14, be provided with at least two clamping devices on welding base plate 14, the first welding base metal 5 is located on welding base plate 14, the first welding base material 5 is clamped by clamping device...

Embodiment 2

[0058] Further illustrate in conjunction with embodiment 1, as Figure 1~12 As shown, the first welding base metal 5 is placed on the welding bottom plate 14, the first welding base metal 5 is positioned against the first side positioning plate 1401 for side positioning, and the first welding base material 5 is clamped by the pneumatic clamp 11 and the pneumatic turning clamp 13. Welding base metal 5.

[0059] The second welding base material 6 leans against the second side positioning plate 1003 on the first cylinder 1002 for side positioning, and the second welding base material 6 is pressed by the pressing plate 1004 .

[0060] Then select the second welding base material 6 to rotate the entire vertical fixture 10 on the support column 1001, select the angle of rotation through the angle dial 1007, and lock the vertical fixture by rotating the locking handle 1005 after rotating the appropriate angle 10, release the vertical clamp 10 to adjust the weld distance between the ...

Embodiment 3

[0064] Further description in conjunction with embodiment 1 or embodiment 2, as Figure 1~12 As shown, the full penetration method includes: the ultrasonic flaw detection of the first welding base metal 5 and the second welding base metal 6 is qualified, and there must be no lack of fusion, air holes, slag inclusions, undercuts, welding flashes, weld fillet heights, and weld gap widths. Nonconforming defects.

[0065] Determine the weld groove, the first welding base metal 5 and the second welding base metal 6 are k-shaped grooves or x-shaped grooves.

[0066] Select the circular liner 12 to stick to the large groove side of the k-shaped groove, and the diameter of the circular liner 12 is 5-10mm.

[0067] According to the welding principle that welding current × welding voltage ÷ welding speed is equal to linear energy, determine welding current, welding voltage, welding speed, root welding: 300 ~ 320A, 30 ~ 32V, 30 ~ 36cm / min, filling welding: 280 ~ 300A, 30~32V, 30~36cm / m...

Abstract

The invention provides a full-penetration welding device for a weld joint of a welded part and a welding method of the device. A gasket is arranged on one side of the weld joint of a first welding base metal and a second welding base metal, the gasket makes contact with the weld joint of the first welding base metal and the second welding base metal, a welding bottom plate is further arranged, atleast two clamping devices are arranged on the welding bottom plate, the first welding base metal is arranged on the welding bottom plate, the first welding base metal is clamped through the clampingdevices, a vertical fixture is arranged on one side of the welding bottom plate, the second welding base metal is arranged on the vertical fixture, the vertical fixture is arranged on the welding bottom plate through a supporting column, and the vertical fixture is rotationally connected with the supporting column. A round-strip-shaped ceramic filler strip is adopted, welding technological parameters are improved, automatic control welding is conducted, and the purpose that a welding robot conducts full-penetration welding on the weld joint of the welded part is achieved. The welding device iseasy to operate, the quality is reliable, back chipping is reduced, and the work efficiency is improved.

Description

technical field [0001] The invention relates to the field of full-penetration welding, in particular to a full-penetration welding device and a welding method for weld seams of welded parts. Background technique [0002] At present, the working process and method of the welding robot welding technology for the full penetration weld of the weldment is to weld one side first, root welding, filling welding, cover welding, and then turn over to prepare for welding the reverse side, and perform root cleaning and welding. Bottom welding, filling welding, cover welding. One is that the welds of the welded parts that are welded now often have unfused welds; the other is that after fusion, there is a poor groove shape on the reverse side, and the welding can only be performed after cleaning the root. The current technical method has low work efficiency, low quality pass rate, and low cost. high. In addition, carbon arc gouging is generally used for root cleaning on the reverse side...
