介绍了 10 0m铝烟囱交流钨极氩弧焊工艺。提出了防止焊接变形措施和劳动保护措施 ;解决了L2纯铝焊接时难熔合、易焊塌、易夹钨、易产生气孔和裂纹以及小铝筒内焊缝如何成形的问题。焊接接头一次探伤合格率达到 96 .8% ,所焊接头成形美观 ,力学性能良好。
The AC TIG welding process of 10 0m aluminum chimney is introduced. Proposed to prevent welding deformation measures and labor protection measures; solves the L2 pure aluminum welding refractory, easy to solder collapse, easy to clip tungsten, easy to produce pores and cracks and small aluminum tube weld how to shape. Welding once a test pass rate of 96.8%, the welded joint beautiful appearance, good mechanical properties.
