Dissimilar Metal Welding Methods. Laser welding dissimilar metals fiber lasers filler material. The specific methods you use for the solution will vary depending on the metals youre welding together.
A few issues commonly encountered in dissimilar metal welding using fusion and conventional fusion welding techniques actually formation of brittle intermetallic phase is also found in solid-state welding. Ultrasonic welding is also used for welding dissimilar metals since very little heat is developed at the weld joint. Weld zone has a cast solidified structure while the base metal has a wrought structure The chemical composition of deposited weld metal is over-mismatch or under-mismatch to that of the base metal based on the required joint strength.

Various dissimilar combinations of metal have been welded including steel to copper base alloys steel to aluminum. The work discussed several criteria for the selection of interlayer such as physical properties metallurgical compatibility mode and thickness of the interlayer. The composition of the intermetallic layer. The processes available for joining dissimilar metals are.
