Abstract: An improved laser welding method of materials by means of long pulse and high energy pulses of solid state lasers in such a manner that large depth of penetration with full depth or partial depth of penetration can be achieved with minimum surface evaporation in first pass of laser beam and enhanced surface smoothness having average surface smoothness of 5 mm by second pass of laser beam of lower power density and inclined at a particular inclination.
