ABSTRACT
This work investigated the hardness tensile, and impact strength of aluminum A6063T5 welded pipe joints at the heat-affected zone. The Taguchi method is employed to optimize the welding process parameters namely current travel speed. Hardness, Impact and tensile tests were conducted to assess the mechanical properties of the Heat Affected Zone (HAZ). The Taguchi method reveals the optimal combination of welding parameters of current 100amps, voltage 33volts and travel speed of 13inches/mm to give a Brinell hardness number of 74.80, impact strength of 0.0181 J/mm2 and tensile strengthof 154.20 MPa. This study provides insights into the mechanical properties namely hardness, impact and tensile strength of A6063T5 aluminum alloy welded joints pipe at the HAZ.
