It is well known that welding deformations influence strength and ductility of weldments. In the
present report, attention is forcussed to the effect of welding conditions, such as weld heat …
抄録 It is well known that residual stresses due to welding influence the initiation of weld cracks and the strength of welded structures. In the present report, attention is forcussed to …
The characteristics of thermal pinch effect of arc in welding process are studied to clarify its
mechanism. A simplified model based on energy balance between ohmic heating and …
