[0004] However, compared with ordinary TIG welding, the double TIG welding process involves more parameters and the process is more complicated. The adjustment and cooperation of the posture of the two welding torches (including tungsten pole angle, tungsten pole distance, tungsten pole height, etc.) is the key to obtaining high-quality welds. The essential

The invention relates to a high-speed welding device for a double-TIG (tungsten inert gas) welding gun thin-wall steel pipe, which comprises two independent welding gun regulation mechanisms, wherein each welding gun regulation mechanism comprises a rotatable sleeve; the rotatable sleeve is formed by the method that the middles of two shell rings are sheathed; one end of the one shell ring is provided with a welding gun sleeve clip; the other shell ring is provided with a vertical shaft which can be rotatably sheathed and connected with the sleeve of a lateral transmission rack; according to opposite rotation of the two shell rings, the rotation of the welding gun in a plane vertical to the welding plane is realized; the rotation of the welding gun in a plane parallel with the welding plane is realized by the opposite rotation of the vertical shaft and the sleeve; the lateral transmission rack is fixedly arranged on a height lateral and bidirectional regulation device; the height lateral and bidirectional regulation device is fixedly arranged on a vertical transmission rack and comprises a lateral sleeve, a lateral position regulation knob, a vertical sleeve and a vertical position regulation knob; one of the vertical transmission racks of the two welding gun regulation mechanisms freely slides on a guide rail parallel with the welding direction; and the other vertical transmission rack is fixed on a guide rail extension cord. The high-speed welding device for the double-TIG welding gun thin-wall steel pipe has the advantages of flexibility in regulation and convenience in use.
Description
technical field [0001] The invention relates to a welding device, in particular to a device for clamping a welding torch and adjusting its attitude in a double TIG high-efficiency welding process. Background technique [0002] Welding technology is the key technology of steel pipe production at present, which determines the quality and efficiency of steel pipe production. For thin-walled (wall thickness ≤ 3mm) steel pipes, DC TIG welding is one of the main welding production processes. However, limited by the shortcomings of TIG welding, such as low deposition rate and shallow penetration, the current welding speed has become a bottleneck for increasing the output of thin-walled steel pipes. Actual production experience proves that simply increasing the welding current and increasing the welding speed cannot achieve stable high-speed welding and obtain high-quality welds, but as the welding speed increases, forming defects such as undercuts and hump welds appear, which serio...
