摘要
Abstract
In this paper,it were introduced the basic principles and process characteristics of resistance spot welding for the rolling stainless steel plate according to the actual production.The welding defects were emphatically introduced,such as:the weld nugget diameter no meeting the standard,shrinkage,welding spatter,lack of fusion,the lacking penetration rate,over-burning,bad appearance. Causes for the defects were analyzed and preventive measures were taked.such as the following influencing factors:welding current, electrode force, welding time, the workpiece assembly, electrode shape and material, and etc.The commercial quality of stainless steel car body has improved through technology means to enhance the quality of solder joint.关键词
