电阻点焊电动机支架断裂失效分析
首发时间:2010-07-07
摘要:对电阻点焊电动机支架高频振动破坏试样进行了失效分析。通过焊材成分分析、断口形貌分析和微观金相组织分析,结果表明固定电动机支架发生断裂的原因是由于焊接工艺不当所致。因此在焊接过程中应该适当改变焊接工艺参数,调整焊接规范。

Failure Analysis of Resistance Spot Welding Motor Bracket
Abstract:In this paper failure analysis was made on resistance spot welding motor bracket test specimens who were destroyed by the high-frequency vibration. Welding component analysis, macro-morphology inspection analysis 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.
Keywords: resistance spot welding break macro-morphology inspection metallographic structure
