摘要：
Gas tungsten arc welding process can be adaptable for all metals and can be used for all welding positions. It can be operated in both continues and pulsed mode current. The present study has been carried out with pulsed current gas tungsten arc welding of Inconel600 with three passes, and the filler wire of ERNiCrMo-3 has been considered. The single V-groove is employed for joining the plates with three passes welding. The residual stresses and tensile strength in weldments are studied. X-ray diffraction (XRD) technique is used to measure residual stresses. The measurement is carried out on the surface across the welding direction. The tensile residual stresses are observed at the fusion zone. The tensile strength of the weldment is higher than that of the base metal.
