Abstract

A combined experimental and numerical approach was adopted to investigate the focused-tungsten inert gas welding process by producing bead-on-plate welds in Inconel 718 plates. Experimental investigations were carried out by means of thermocouple measurements and optical macrographs of the weld cross-section. Three-dimensional finite element simulations were conducted using the commercial specialized finite element software Sysweld in order to predict the thermal field induced by the process in the plates. The work presents an approach to investigate the process efficiency and calibrate the heat source model in order to produce a full thermal characterization of the plasmatron welding apparatus.
