Abstract:
The ability to laser weld automotive components is a determining factor in converting the currently specified wrought or cast materials to powder metallurgy (P/M) parts for various applications. Material selection, process conditions and joint design are known to have a significant influence when fusion welding P/M components. Welding trials were conducted to determine the appropriate laser parameters for several P/M grades at various density levels. Bead-on-plate, overlap and butt joint designs were attempted, primarily without filler metal additions.
