| 摘 要： | 因锌合金不易焊接,采用加入焊剂的方法对新型模用锌基合金(ZA合金)进行了TIG焊接。通过金相显微镜、X射线衍射等分析方法对焊接接头组织及焊后残渣采样进行分析,并对焊剂的作用机理进行了初步研究。结果表明:焊接过程中,焊缝表面形成大量氧化物;加入焊剂的主要作用是通过冶金反应清除焊接材料表面的氧化膜,同时向焊缝中过渡Zn。

| Abstract: | Because of zinc alloy not being welded easily,the new mold zinc based alloy(ZA alloy)is weld by adding flux.In orere to discuss the action mechanism of the fluxes,the microstructure of the joint and residue after welding are analyzed with metallographic microscope and XRD.The results show that large amount of oxide in the surface of the weld is generated in welding process,main action of the flux is removing the oxide film in the surfacof the welding material by metallurgical action,and at the same time,of ZnCl2 can thansit Zn into welding seam. |
