Problems solved by technology

During the welding process, due to external shocks, the welding cable changes or affects the up and down lateral swing width of the laterally oscillating torch, so that the arc becomes unstable, weldability decreases, and defects are generated at the welding bead
[0013] Moreover, the welding torches of the prior art that swing laterally also have the following problems, that is, in the welding process of ships and the like, when the welding quality is poor due to a large number of welding beads, spatter, various internal defects, it is necessary to restart the welding process. Start the welding process

Abstract

The present invention relates a weaving torch device for auto welding that can maintain necessary molten metal for desired welding such as welding by a person and provide the best welding beads, by locking a hinge pin and a conveying pin, which are provided to both sides of a weaving torch of a torch device connected to a welding machine, to a locking protrusion and a locking step of a hinge support member of a lower case in order to prevent left / right conveying while the weaving torch is automatically reciprocated up / down by operation of an electromagnet and a conveying spring.

Description

technical field [0001] The invention relates to a laterally oscillating welding torch device for automatic welding, in particular to a laterally oscillating welding torch device for automatic welding, which uses both sides of the laterally oscillating welding torch of the welding torch device connected to the welding machine The hinge pin and the delivery pin are fixed on the positioning protrusion and the fixing boss of the hinge support element of the lower shell, so that when the welding torch is reciprocating up and down automatically, it can be moved by the action of the electromagnet and the delivery spring. Stops the gun from moving left / right, thereby maintaining the necessary molten metal for ideal welds, such as manual welding, and providing an optimal weld bead. Background technique [0002] Generally speaking, the welding process performed under working conditions, such as in shipbuilding yards, is generally divided into manual welding performed by personnel and ...
