Abstract: The diamond impregnated segments and the steel core were laser welded in a horizontal arrangement to achieve very high bond strength between them. A parametric investigation was conducted to evaluate the effect of several essential variables on high power laser beam Welding, which include beam mode, power level, weld speed, focal Point position, Plasma Suppression and beam alignment.
The results showed that beam mode, power level, weld speed, Plasma suppression along with focal point position are the Primary parameters, which can influence the depth of penetration of laser welding. Beam alignment can greatly affect the amount of pores in the welded seam.
