TIG of GH4169 alloy tube is car-ried out in this paper. Macrostructure of welded joints is obserbed, and the quality of the joints is checked by X ray. Within 20mm of weld area has been grinded and scraped at the welding joints end before welded, and the optimiza-tion tack welding parameter and welding parameter have been utilized during welding. Results show that the quality of welded joints is well and without weld defects.
