EFFECT OF TIG WELDING ON ALUMINIUM MATRIX COMPOSITE

Abstract

Metal Matrix Composite has evoked a keen interest in potential applications in aerospace and automotive industries, owing to their superior strength-to-weight ratio and temperature resistance. Nowadays, welding strength on composite materials is more essential. So, in this project, we consider the effect of TIG welding on aluminium matrix composite (Al & Sn). The TIG welding on aluminium alloys like (Al 6061& Al 6063) has lost its welding strength by around 30% in Al 6063 & 50% in Al 6061. To regain the welding strength, we need a heat treatment process like hardening and tempering, which is a more costly and time-consuming one. To eradicate this problem, we will mix the malleable Tin (Sn) in different ratios of 90:10 and 85:15 for the aluminium alloys (Al 6061 & Al 6063). Then analyzing the effect of TIG welding on the aluminium metal matrix, the welding strength of the aluminium metal matrix composite is increased by 5% compared to the previous material.
