Abstract

Hardness is defined as the withstanding capability of metal against penetration. Welding produces metallurgical transformations. Evaluation of hardness gives insight into these transformations. A proper study on weldment micro hardness will pave the path to enhance the mechanical reliability of the weldment. Thus, a study on mechanical and microhardness properties of 5052 aluminum alloy weldment using nonpulsed and pulsed current welding at frequencies of 2,4,6Hz has been carried out in the present work.
