Metal matrix composites continue to be desirable structural materials but difficulties in joining limit their usefulness. This paper describes the results of a study on the laser welding of A356‐AI/SiC particulate composites. Three separate processing regimes are identified based upon analytical model predictions and metallographic analysis of the solidification structures.
