Resumen

Welding duplex stainless steels with Nd:YAG pulsed laser welding results in an unbalanced microstructure. The present article reports the effects of nickel addition on the microstructure of UNS S32750 duplex stainless steel welded with an Nd:YAG pulsed laser. Two conditions were used: autogenous welding and welding with the addition of nickel. The addition of nickel resulted in equal proportions of austenite and ferrite in the weld bead, affecting the microstructure.
