Experimental Analysis on Mechanical Properties with Microstructures on Aluminium alloy 6070 Welds with H14 Steel

Abstract

bstract: TIG welding stands out as a highly precise and efficient welding technique, proficient in joining both ferrous and nonferrous metals. This method offers exceptional control, produces minimal fumes and spatter, and results in a clean weld that often requires little to no finishing. The focus of the current research is on determining the optimal combination of welding parameters for TIG welding of Al6070 and H14 materials. The literature survey reveals the inherent difficulty of welding aluminium using conventional arc welding processes. A multitude of welding parameters significantly influences both the quality of the welds and their repeatability. This study systematically investigates various parametric ranges and their effects. The TIG welding setup employed in this specific study will weld 10mm thick Al6070 and H14 plates, adhering to the prescribed welding parameters. The impact of these parameters on the tensile and impact strength of the welding joints, as well as the microstructural characteristics, will be thoroughly analysed.
