摘要
针对宇航零件防晃板的焊接，提出了用三相次级整流电阻焊的方法替代手工钨极氩弧焊的方法，这不仅可以提高焊接效率，更主要的是消除对操作人员技艺的要求，保证产品的质量。通过对电阻焊各种工艺参数、工艺措施下焊点组织和力学性能的测试分析，了解了影响焊点质量的主要因素，实验表明电阻焊接头完全符合有关标准的要求。
To replace the method of manual TIG,3-phase DC resistance welding method is discussed in this paper when welding the anti-swing board of aerospace vessel.It offers a number of advantages as high efficiency,and requires less skill to perform,consistent weld quality can be maintained.Some welding variables which affect the quality is studied.Testing results show that resistance spot weld is in accordance with the relevant standards.
