Abstract Weldability of three steel combinations {ferritic(UNS G10800), austenitic (UNS G30400) and super duplexstainless steels (UNS S32760)} by pulsed 600 W Nd:Yag laser is presented. The study attempts to explore theeffect of two different welding speeds (300 and 400 mm/min) on the nature of diverse weld zone morphology andjoint strength of dissimilar welds. Microhardness at thetop surface of the weld zone and heat affected zone (HAZ)is superior to middle and root section of welds. Tensilestrength of the welds was higher at lower welding speed(300 mm/min) for all combinations and maximum tensilestrength is obtained for SS 304-SDSS combination. Maximum and minimum corrosion rates are observed in ferriticsteel and super duplex stainless steel, respectively
