Failure analysis of welding nut on the cover plate of

Apr 21, 2021 · An automobile power company discovered the surface defects and the missing corner after spot welding, ring welding, and surface turning (shown in Fig. 1a) on the cover plate during the assembly process of the hydraulic torque converter. Welding nut is a sort of fasteners, which ensures the reliability of the hydraulic torque converter cover plate to be connected. Fracture failure for the teeth of sprocket wheels in Nov 01, 2020 · The service time of the sprocket wheel was about 2 min. The rotational speed was 44.48 r/min, and the force acting on the sprocket wheel was 181.2 KN. The sprocket wheel was made of 42CrMo steel according to GB/T 3077-2015. And it was normalized after forging.
