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.
该研究的目的是在进行单次焊接时，研究能量和光斑直径等激光焊接参数对铸造钴铬合金焊缝熔深的影响。在该研究的限制范围内，随着电压升高且光斑直径减小，熔深增加。然而，扫描电子显微镜研究表明，在这些情况下，焊接区域存在更多缺陷。临床意义在于，在选择焊接参数时，应考虑待焊接部件的厚度，以获得扩展的焊接区域且不产生微观结构缺陷。
