High strength low alloy steel (HSLA DOCOL 500 LA) is utilized in the automotive structure because of its superior qualities such as good fatigue resistance, a high strength-to-weight ratio, assisting reducing weight vehicle, increasing fuel efficiency and lower CO2 emissions. Resistance Spot Welding (RSW) most welding technique that used to join automobile parts together. This study investigate...

Abstract Double-sided friction stir welding (FSW), performed with a pair of rotation tools, was studied in an attempt to increase the joining speed when applied automotive advanced high-strength steels (AHSS). The experiments were on butt joint 1.6-mm-thick 1180 MPa grade steel sheets, and sound welds obtained travel no more than 4 m/min, fairly comparable laser beam (LBW), one conventional pro...
