PCGTAW the heat required to melt the base material is supplied only during the peak current pulses allowing the heat to dissipate into the base material. In the present investigation, an attempt has been made to multipass weld the Inconel to Inconel material using the PCGTAW; ERNiCrMo-3 filler wire is used for the experimentation. The investigation involves metallurgical and mechanical properties of pulsed current gas tungsten arc welding onInconel 600. In this work, an attempt has been made to investigate the double v-grooved weldability; metallurgical and mechanical properties of the PCGTA welded with Inconel 600 similar materials, mechanical property relationships of Inconel 600 weldments are discussed in detail.

Dissimilar welds of Monel 400 and AISI 316 are extensively used in boiler feedwater heat exchanges, petrochemical industries, nuclear industries where moderate weld strength and high corrosion resistance are required. In this paper, dissimilar welded joint between Monel 400 and AISI 316 have been developed by employing Tungsten Inert Gas (TIG), pulsed TIG and Interpulse TIG welding techniques. The heat input rates and filler wire for joining the base metals were same for three welding techniques. The developed weldments have been inspected by employing X-ray Radiography Test (XRT) to determine the macro/ micro defects. The tensile properties of weldments have been evaluated. The ultimate strength of TIG, pulsed TIG and Interpulse TIG weldments were observed to be 528 MPa, 542 MPa and 588 MPa, respectively. The tensile properties of Interpulse TIG weldments are superior to that of welds made of other two welding techniques. © 2019 Elsevier Ltd. All rights reserved.

Evaluation of residual stress in multipass dissimilar butt joints using X-ray diffraction

This paper investigates the weldability, metallurgical and mechanical properties of the dissimilar joints of Inconel 625 and AISI 304. Dissimilar joints were obtained by gas tungsten arc welding process employing ERNiCrMo-3. Tensile fracture occurred at the parent metal of AISI 304 in all the trials. The structure-property relationships on these dissimilar weldments were evaluated using the combined techniques of optical microscopy and SEM /EDAX techniques.

Investigations on Dissimilar Weldments of Inconel 625 and AISI 304

Inconel 625, a Nickel based superalloy has outstanding features such as high corrosion resistance and high strength. Inconel 625 is preferred and widely used in aerospace, nuclear and power plant components where they are exposed to elevated temperatures. In this work, an attempt has been made to investigate the weldability, metallurgical and mechanical properties of the PCGTA welded Inconel 625 metals employing ERNiCrMo-3 filler wire. Structure-property relationships of Inconel 625 weldments are discussed in detail.
