Abstract

Nd-YAG laser pulses were used for investigating weld metal composition change in 200 μm deep, 304 stainless steel microjoints. The electron microprobe analysis helped in determining the concentrations of iron, manganese, chromium, and nickel after welding. Three-dimensional transient heat transfer and fluid flow models were developed for simulating the temperature field as a function of time. Vaporization rates of various alloying elements were calculated that indicated that the vaporization took place mainly from a small region near the center of the beam-workpiece interaction zone, where the temperatures were very high.
