摘要: It is important to understand the formation mechanisms and preventive procedures of welding defects as well spot bead phenomena with pulsed or continuous wave lasers. This chapter first describes effects factors conditions on weld penetration, laser-induced plume behavior, interaction between a laser beam its induced plume, keyhole suppression porosity pores solidification cracking in welding. also discusses in-process monitoring adaptive control during for prevention holes lap welds constant widths
