Control weld geometric parameters when wet underwater welding
Pidvodni tehnologii, 2020 The aquatic environment has a significant impact on the efficiency of heat input to the base metal, significantly reducing the efficiency of the arc. As a result, in wet underwater welding, the penetration of the base metal is reduced compared to welding in the air with the same mode parameters.
