摘要
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。
A procedure of TIG welding for L2 aluminum chimney with 100 m height i s suggested. The welding materials, welding equipment and welding parameters are selected to solve the problems of lack of fusion, blowhole, crack and tungsten inclusion etc. in welding of L2. Welding deformation control and labour protecti on are also discussed. It is proved that the welded joint has good appearance of weld and mechanical properties and the qualified rate of X-ray detection can re ach up to 98%.
