Development and Performance Analysis of a Seam Welding Machine for Thin Plate Applications

Abstract

Resistance Seam Welding (RSEW) is a welding process that uses rotating wheel-shaped electrodes to produce a continuous weld along the seam of the workpiece. RSEW is used for welding metal sheets and utilizes electrical resistance as its heat source. The welding technique applicable to RSEW is the lap joint configuration. In this study, steel plates with thickness variations of 0.15mm, 0.2mm, and 0.3mm were welded using a current of 20 amperes and a welding speed of 3.125 mm/s. The thickness of the welded plates can affect the welding outcome. For the welding process, a current of 20 amperes was used on specimens with lap joint configurations. The specimens were subjected to tensile testing using a tensile testing machine with a capacity of 30 tons. The test specimens included three types of steel plates with varying thicknesses of 0.15 mm, 0.2 mm, and 0.3 mm. The results of the tensile tests indicated that, with the same welding parameters, the tensile strength decreased as the material thickness increased.
