复合载荷作用下的点焊联接检验方法

The examination way of spot welding link for complex load

点焊联接的质量检验是点焊联接的研究课题之一 ,传统的检验方法只对点焊联接两个方向进行拉伸 ,在复合载荷作用下 ,仅两个方向的拉伸强度还不足以作为设计依据 ,本文设计的新试样可以较好的解决这一问题。

The quality examination of spot welding link is one of the study subject of spot welding. The traditional examination method is only to pull two direction. To complex load, aren,t enough for the foundation of design. This paper design a new example to solve this question.
