Abstract

Welding process is generally used in manufacturing industry. It usually produces distortions in the weld metal. To reduce distortion, one of the methods used is the pre-strain. This study aims to determine the effect of pre-strain during welding process on the residual strain of dissmilar metal weld between stainless steel and carbon steel. Gas Metal Arc Welding (GMAW) process is performed to make butt joint of SUS 304 stainless steel and SS 400 carbon steel with a length of 300 mm, width of 150 mm and thickness of 5 mm. Welding current, welding voltage and welding speed are 240 A, 24 V, 390 mm/min respectively. During welding, stainless steel sheet is pre-strained in elastic, yield, and plastic levels. Strain measurements are performed using the neutron diffractometer which is conducted in Batan, Serpong, Indonesia. Pre-strain lead to increase the strain on the longitudinal direction of weld line. However, further away from the weld area, the strain decreases compared to the unpre-strained specimens.
