초록
Recently, corrosion problems caused by quarantine disinfectant have occurred in the door panel of commercial trucks. As a way to solve this problem, a drain hole is being drilled in the door panel, and the door panel is being designed again for this purpose. Reinforcing parts such as frames or brackets for rigidity are attached to the inner and outer door panels, and spot welding is performed for assembly. X-rays and nugget diameter measurements of the welds were performed to confirm the results of performing according to various conditions for such spot welding. Through this study, it was confirmed that the pressing force had a greater effect on the welding quality than the amount of welding current.
