摘要

电阻点焊广泛应用于汽车车身及其设备部件的制造。本文介绍了闭式薄钢板电阻点焊接头的超声无损检测方法和结果。在无损检测后，根据焊接接头面积对无损检测结果进行了验证。利用所得结果，开发了一种封闭型材与钢板点焊接头的评定技术，可用于使用这种接头的工厂。此外，本文还对开发的评估技术与目前使用的破坏性评估方法的成本进行了比较。

The analysis of spot welding joints of steel sheets with closed profile by ultrasonic method

Resistance spot welding is widely used in the fabrication of vehicle bodies and parts of their equipment. The article presents the methodology and the results of non-destructive ultrasonic testing of resistance spot welded joints of thin steel sheet with closed profile. Non-destructive test results were verified on the basis of welded joint area after destructive testing. The obtained results were used to develop an assessment technique for spot welded joints of closed profile with steel sheet, which could be used in factories employing such joints. In addition, the article makes comparison between the costs of the developed assessment technique and currently used destructive method.
