Control weld geometric parameters when wet underwater welding

open access: yesPidvodni 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.

Thermo-mechanical analysis of linear welding stage in friction stir welding: Influence of welding parameters [PDF]

open access: yesThermal Science, 2022
The influence of friction stir welding parameters on thermo-mechanical behavior of the material during welding is analyzed. An aluminum alloy is considered (Al 2024 T351), and different rotating and welding speeds are applied. The finite element model consists of the working plate (Al alloy), backing plate and welding tool. The influence of the welding
