本文介绍了钍钨极脉冲氩弧焊自动焊接薄壁管环焊缝的新工艺,解决了多年来焊接中的未焊透、气孔、裂纹等问题。文中还叙述了用母材代替焊丝焊接薄壁角环焊缝,确保被焊工件的机械强度,提高了产品质量。
This paper introduces the new technology of automatic welding of thin-walled tube-ring weld with thorium tungsten pulse argon arc welding and solves the problems of incomplete penetration, porosity and cracks in the welding over the years. The article also describes the use of base metal instead of wire welding thin-walled corner ring weld to ensure the mechanical strength of welded parts and improve product quality.
