Automobile manufacturers have attached great importance to the light weight of vehicles and NVH performance. Under this background, laminated vibration damping steel sheets (VDSS) are increasingly used in automotive parts. The engine oil pan stamped from this steel plate has obvious effects on the weight reduction and noise reduction of the engine. For the welding of VDSS, the welding process of single-layer steel plates is generally directly adopted in the industry. However, this process is likely to cause Pin-Hole defects in the VDSS. In products with sealing requirements like oil pans, this defect can easily lead to seal failure. Aiming at eliminate this kind of defect, this article explored the formation mechanism of Pin-Hole defect on the base of experimental results and put forward effective improvement methods. The improvement effect was verified through multiple rounds of routine endurance tests.
