it confirmed the main factor affecting the welding quality is the welding-torch is not associated with weldment movement, which caused welding-torch angle and arc length changed in the welding process. It’s easy to result in welding defects when the welding-torch angle is less than 30° , ...

"narrow-groove" welding, which requires less heat input than before with the use of small-size electrodes. Still, the proposed method when adopted for the welding of thick plates gives defects as illustrated in FIG. 1. According to the method, fillet welding of the groove walls is carried ...
In view of this, the problem to be solved is that of proposing an improved MIG welding device, meaning one that makes it possible to increase the welding speed without the resulting weld beads having any “humping” defects, does not excessively complicate the welding insulation, does not requi...
