Impact of weld restraint on the development of distortion and stress during the electron beam welding of a low-alloy steel subject to solid state phase transformation

International Journal of Mechanical Sciences, 2021
Electron beam (EB) welding has a low tolerance to inter-part gapping distortion and can generate complicated stresses, which pose challenges to weld quality and integrity. This study investigates welding distortion and stresses in an EB welded plate made

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.

Direct keyhole laser welding of aluminum alloy AA5754 to titanium alloy Ti6Al4V [PDF]

, 2014
The tensile strength of direct AA5754/Ti6Al4V joints performed by high speed Yb:YAG laser welding is found to be determined by morphology and phase content of dissimilar interface formed between contacting Al-rich and Ti-rich melted zones. Three types of
