Effect of Welding Parameters of the Nd:YAG Laser on the Penetration Depth of Cobalt Chromium Alloys

10.1922/EJPRD_1044Radford06

Abstract - The aim of the investigation was to study the effect of the laser welding parameters of energy and spot diameter on the penetration depth of the weld of cast Co-Cr alloy when a single weld was performed. Within the limitations of the study as voltage increased and the spot diameter decreased, penetration depth increased. However, SEM investigation showed more defects in the welded area under these circumstances. The clinical significance is that during selection of the welding parameters the thickness of the components to be welded should be considered to achieve an extended welded area without the induction of micro-structural defects.

KEY WORDS: Cobalt chromium, Nd:YAG laser, welding parameters, focal spot size, energy.
