Investigation on strength of resistance spot welding joint of copper and brass using various filler materials

Abstract

Copper and Brass are widely used in Auto electrical industries due to their good electrical conductive properties. This is possible as free electrons in metals can move through, allowing metals to conduct electricity. Resistance spot welding process (RSW) is the highly preferred welding process especially for electrical connector terminals because of its reliability over Copper and brass joints and attained importance in automotive sectors. Present work is focused on the behavior of various filler materials used in between Copper and Brass in resistance spot welding process by which the strength of weld joints is being analyzed.
