The New Technology of Softening Control for Copper Weld Joint Using Pretension Method

Abstract:

In conventional TIG welding, copper weld joint and its heat affected zone (HAZ) have the disadvantage of softening. In this paper, the new technology of softening control for copper weld joint using pretension method was studied. The results show that hardness of copper weld seam and its HAZ was increased by pretension. Moreover, the tensile strength and elongation of the welding joint were obviously improved. Keywords: pretension, weld joint, softening control, copper
