Simulation of welding temperature fields during TIG arc the welding process of Cr-Mo steel bar (ASTM A304) was studied. The results of Simulation models of welding processes help to predict welding parameters effects on the temperature field during and after welding and by this, the failure rate could be estimated and minimized. This paper presents the welding profile model, assembled from 100 mm by 50 mm by 20 mm thick, a Double-Sided Half V-Groove Weld Joint, moving heat source was employed to methodically examine welding temperature fields and transformation in the single-pass butt-welded joint. Unfortunately, the precision of the model rests on many parameters, which cannot be precisely dictated. To resolve this proposition, a calibration process was made by using a Datalogger type K thermocouple -3 channel-LU-MTM-380SD during the welding process on Cr-Mo steel bar. The obtained Experimental results were used as input to run the simulation. Depending on weld joint profile, temperature fields were discovered to vary with distance from the weld centerline which altered the yield stress of weld metal. To realize this goal, a pattern of the 3D model of heat transfer with a moving heat source during welding was simulated in Autodesk Inventor Simulation CFD 2018 Application Software. The results shown that the welding temperature fields have a higher value at the welding center line and decreased towards the edges of the bar. An indication that simulation is a veritable tool to access likely consequence of the welding process at both welded and non-welded portions of steel bar before real machine structural development.

“…Applications of Chromium-Molybdenum (Cr-Mo) steels in various capacities such as oil refineries, fertilizer plants, and power plants, at service temperature of up to 600°C and pressure of 30MPa established its value [3]. Remarkable oxidation resistance, resistance to sulfide corrosion and high-temperature strength, are good properties that distinguished Cr-Mo from other low-alloy steels and are derived functions from chromium and molybdenum alloying elements and they improve with the increase of alloying elements [4]. Tungsten inert gas (TIG) welding, used to weld Cr-Mo steels, arc welding process that produces metal joints by melting process, heating with an arc between a non-consumable electrode and the base metal [4,5].…”
