Description

Technical Field

[0001] The invention relates to the technical field of steel welding, and in particular to an auxiliary welding device for a joint of non-magnetic steel and carbon steel. Background Art

[0002] The relative magnetic permeability μ value of non-magnetic steel is slightly greater than 1, and the magnetization effect in the magnetic field is very weak, that is, the so-called "non-magnetic" phenomenon occurs, so it is figuratively called non-magnetic steel. As a functional steel material, non-magnetic steel basically does not produce magnetic induction under the action of a magnetic field. The room temperature structure of non-magnetic steel is required to be stable austenite. This is because ferrite, pearlite and martensite structures are ferromagnetic at room temperature, and show strong magnetization in a magnetic field, with high magnetic permeability, while austenite with a face-centered cubic structure is paramagnetic and has very low magnetic permeability. By appropriately adding alloy elements to expand the austenite zone in the Fe-C alloy phase diagram and heat treatment methods, a stable single-phase austenite structure can be obtained at room temperature, thereby keeping the magnetic permeability of the steel material at a low level; carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. It is also called carbon steel. It generally contains a small amount of silicon, manganese, sulfur and phosphorus. Generally, the higher the carbon content in carbon steel, the greater the hardness and strength, but the lower the plasticity.

[0003] Non-magnetic steel is cast from low-carbon steel with manganese added. It has poor plasticity, large thermal expansion coefficient, and poor thermal conductivity. Due to the poor plasticity of non-magnetic steel, its tensile strength is worse than that of carbon steel. Therefore, when the two are welded together, the welding thermal stress will cause the weld to peel off on the non-magnetic steel side. Non-magnetic steel has poor thermal conductivity, and overheated structures are prone to occur in the heat-affected zone of welding, forming brittle fractures, which affects the welding quality. Summary of the invention

[0045] Working principle: When the non-magnetic steel tube body 541 and the carbon steel tube body 540 are welded and fixed, the non-magnetic steel tube body 541 and the carbon steel tube body 540 pass through the rotating circular frame 904 on the protective frame 2, and the servo motor 902 is started. The servo motor 902 drives the roller 908 on the rotating rod 903 to slide in the slide groove of the T-shaped tooth plate 910, so that the tooth block end of the T-shaped tooth plate 910 moves back and forth in an arc shape, so that the T-shaped tooth plate 910 drives the linkage gear 905 to drive the rotating circular frame 904 so that the cleaning brush plate 907 cleans the outside of the non-magnetic steel tube body 541 and the carbon steel tube body 540. At this time, the extrusion spring 906 uses its own elasticity to make the cleaning brush plate 907 fit tightly to the non-magnetic steel The non-magnetic steel pipe body 541 and the carbon steel pipe body 540 are placed outside, and then the non-magnetic steel pipe body 541 and the carbon steel pipe body 540 are respectively placed in the arc clamping plate 531 inside the rotating clamping plate 523, and then the universal motor 524 is started, and the universal motor 524 drives the adjusting gear 525 to rotate the adjusting tooth plate 527, and the arc groove on the adjusting tooth plate 527 drives the pushing cylinder 530 to make the clamping adjustment slide 528 drive the arc clamping plate 531 on the guide cylinder 529 to clamp the non-magnetic steel pipe body 541 and the carbon steel pipe body 540, and then the driving motor 519 is started, and the driving motor 519 drives the belt 520 to rotate the bidirectional screw rod 517, so that the bidirectional screw rod 517 drives the adjusting slider 514 to weld The non-magnetic steel pipe body 541 and the carbon steel pipe body 540 are moved in opposite directions in the sliding mouth on the platform 1, so that the welding point of the non-magnetic steel pipe body 541 on the tooling support plate 516 and the carbon steel pipe body 540 are closely fitted, and then the welding point is welded by the welding gun body 509. At this time, the infrared temperature monitor 512 monitors the welding point and the welding point temperature of the non-magnetic steel pipe body 541 and the carbon steel pipe body 540 in real time. When the temperature of the welding point is too high, nitrogen is blown into the nitrogen release pipe 510 through the hose 1 507 by the nitrogen generator 501, so that the nitrogen cools the temperature of the welding point. At the same time, when the external temperatures of the non-magnetic steel pipe body 541 and the carbon steel pipe body 540 are inconsistent, the amount of nitrogen entering the hose 2 521 is controlled by the metering valve 503. The nitrogen is then cooled through the hollow arc release frame 535 on the metal telescopic tube 534 on the hollow circular frame 532 to cool the outside of the non-magnetic steel tube body 541 and the carbon steel tube body 540. During welding, the electric drive rod 538 drives the adjustment gear rod 537 to drive the linkage gear plate 539 to rotate the rotating clamping plate 523, thereby rotating the non-magnetic steel tube body 541 and the carbon steel tube body 540, so that the welding point and the steel outside are evenly cooled. Through the welding module 5, the temperature of the welding point during the welding process is evenly cooled to avoid overheating of the non-magnetic steel tube body 541 and the carbon steel tube body 540. During the welding operation, the collection frame 6 collects the welding impurities generated during welding.Open the opening and closing cover 8 to collect the impurities uniformly.
