It has the advantages of high current density, concentrated heat, high deposition rate, fast welding speed, and easy arc ignition. In the single-gun argon arc welding of the robotic arm, there are defects in the welding seam due to the down-welding and reverse welding. The double-gun welding is to use two welding torches to weld on a substrate at the same time. Double gun welding has the advantages of high welding efficiency, high welding wire cladding rate and good weld quality. However, the existing manipulator argon arc welding double-torch fixing fixture cannot satisfy the distance adjustment between the double torches and the angle adjustment of the double torches during the double torch argon arc welding, and cannot meet the welding requirements under various process conditions.
