Abstract

一种无压痕点焊工艺，涉及焊接技术领域。将铬锆铜片覆盖在待焊的零件表面，焊枪的电极帽直接作用于铬锆铜片上，通过铬锆铜片将热量传导于待焊的零件表面完成点焊，焊好后去除铬锆铜片。由于铬锆铜的热熔值远大于待焊的零件的热熔值，所以不必担心会将铬锆铜片焊接在零件表面。本发明既能保证能量的集中供应，热量得到良好的传递，焊核成型不受影响，又能使焊点表面无压痕，满足表面质量的严格要求。

Description

一种无压痕点焊工艺
技术领域
本发明涉及焊接技术领域。
背景技术
随着工业技术要求的提高，在许多焊接产品中要求表面无压痕，如车身的水箱横梁。由于后续水箱横梁外侧，将直接由油漆作用零件表面，所以要求表面焊点无压痕，但就目前的焊接方式而言，基本无法达到。
发明内容
本发明目的在于提出一种能实现表面无压痕的点焊工艺。
本发明将铬锆铜片覆盖在待焊的零件表面，焊枪的电极帽直接作用于铬锆铜片上，通过铬锆铜片将热量传导于待焊的零件表面完成点焊，焊好后去除铬锆铜片。
由于铬锆铜的热熔值远大于待焊的零件的热熔值，所以不必担心会将铬锆铜片焊接在零件表面。本发明既能保证能量的集中供应，热量得到良好的传递，焊核成型不受影响，又能使焊点表面无压痕，满足表面质量的严格要求。
另外，本发明铬锆铜片为CuCrZr合金材料制成，具体组分： Cr：0.25～0.65%，Zr：0.08～0.20%，其余为Cu。
具体实施方式
一、制备铬锆铜片：
先制作CuCrZr合金材料，其中Cr：0.25～0.65%，Zr：0.08～0.20%，其余为Cu。
根据需要焊接的工件和零件数模，机加工出铬锆铜片。
二、焊接工艺：
如待焊接的工件材料为铁合金，其中C≤0.12%，Si≤0.5%，Mn≤0.6%，P≤0.1%，S≤0.045%，其余为Fe。
通过夹具将镐铜片的一面与零件的一面覆盖式紧密贴合，固定安装时保证贴合的面为紧密接触。
然后将焊枪的电极帽直接作用于铬锆铜片上，通过铬锆铜片将热量传导于待焊的零件表面完成点焊，焊好后去除铬锆铜片。
三、验收：
通过金相分析，焊接处的焊核成型不受影响，并且焊点表面无压痕。
