Description

A double-gun horizontal automatic welding device

technical field

The utility model relates to a double gun horizontal automatic welding device.

Background technique

In response to the welding needs of large gaps between metal bodies, the transverse welding technology has been developed rapidly. The existing transverse welding methods mainly include the following two types: one is single-gun multi-layer multi-pass welding (the welding torch does not swing during the welding process) , and the other is manual electrode arc welding. The welding forming effect and penetration (the degree of fusion between the molten pool formed by the arc and the base material during the welding process) of these two transverse welding techniques are not ideal, and the back forming effect (the workpiece is welded After completion, the forming effect on the back side of the opposite side of the weld is poor, and the phenomenon of slag inclusion and undercut in the weld is serious. On the other hand, manual horizontal welding often requires very skilled welders to complete, and the welding efficiency is very low.
