Objective: The objective of this study was to investigate the effect of laser welding parameters (current [A], spot diameter [mm], and pulse duration [ms]) on the weld penetration depth by Nd:YAG laser into cast titanium and Ag-based and Au-based alloys.

Method And Materials: Two cast blocks of each metal were laser welded with various parameters at their interface. The blocks were then separated, and the penetration depth into each metal was measured on the separated surface using a computer program.
