Simulation of laser and hybrid laser welding using SYSWELD / Robert Ngendang Lidam

A 3D finite element analysis has been developed and conducted using finite element code SYSWELD to simulate the laser welding process of concealed T-joint welding and hybrid laser welding process of one-sided T-joint. Material used in the research is mild steel plates (S355). The simulation was done...
