Numerical Study on Welding Residual Stress Distribution of Corrugated Steel Webs

Metals, 2022
Residual stresses are an inevitable result of the welded fabrication process of corrugated steel webs (CSWs), resulting in structures with high and unpredictable stress fields, causing unexpected failures.

Comparison of welding residual stress and deformation induced by local vacuum electron beam welding and metal active gas arc welding in a stainless steel thick-plate joint

, 2021
Local vacuum electron beam welding (LVEBW) breaks through the limit of vacuum chamber and can be flexibly proceeded in more working conditions. Using LVEBW to substitute conventional gas metal arc welding will greatly improve production efficiency.
