摘要
Abstract
Fracture failure analysis was made on resistance spot welding motor bracket test specimens which were destroyed by the high-frequency vibration.Component analysis of weld materials, macroscopic analysis of fracture morphology and microscopic analysis of the microstructure show that the reason why the fixed motor bracket was broken was due to improper welding.Therefore, during the welding process the welding parameters should be changed appropriately, and the welding conditions should be adjusted too.关键词
