In this study a pulsed Nd:YAG laser was used to join Hastelloy C-276 thin foil with 100 microns thickness. Pulse energy varied from 1.0 2.25 J at small increments of 0.25 4 ms pulse duration. The macro and microstructures the welds were analyzed by optical electronic microscopy, tensile shear test microhardness. Sound without discontinuities obtained 1.5 energy. Results indicate that using precise control energy, so dilution rate, it is possible weld laser.
