摘要
变极性等离子是一种新的焊接工艺,可以实现不开坡口一次焊透6～16mm厚度的铝合金;焊缝成形美观,宽窄一致,力学性能基本等同母材;X光探伤达到JB4730-94Ⅰ级标准。通过艾美特立式纵缝自动变极性等离子焊接系统与传统工艺“MIG+TIG”焊接设备,在GIS铝合金壳体生产中的实际应用比较,阐述了变极性等离子工艺焊接厚大铝合金的技术优势和在GIS壳体焊接中发挥的重要作用。
VPPAW is a new welding process which can penetrate 6-16 mm Al-alloy without groove, preparation.The welding head is uniform and slinky,which strength is close to the base material.By X-ray inspection,the internal quality of welding head san meet the class I in accordance with the standard of JB4730-94.Comparing the application of AMET automatic VPPAW welding process with traditional MIG ＋TIG process, this article expounds the advantages nf VPPAW in GIS Aluminum tank manufacture.
