The pulsed Nd-YAG laser welding process is an excellent method for joining dissimilar metals. The ability to focus the beam to a small spot size and the capability with a precision CNC positioner to locate the beam very precisely, permits close control of the fusion zone composition. The nature of the pulsed laser process requires that the fusion zone composition exhibit good cracking resistance. Frequently a filler metal can be introduced which will tolerate the dilution from both of the base metals and produce a crack-free weld. Examples are cited to illustrate a number of dissimilar metal combinations. 4 refs., 12 figs.
