研究接头形状、钎缝厚度对焊后残余应力的大小及分布规律的影响。
The effects of joint shapes and filler metal thickness on the distribution of residual stress were researched.
通常，影响焊接接头性能的力学因素有焊接缺陷、接头形状的不连续性、焊接残余应力以及焊接变形。
The mechanical factors for the property of welding joint are welding defects, discontinuity of joint shape, welding residual stress and welding distortion.
因此为了获得较高的接头形状恢复率，在满足抗拉强度的基础上，应优先考虑采用随机后热处理工艺。
So under the precondition of tensile strength need, it is necessary to employ the CPHT processing in order to get high SRR joint.
