The invention discloses an all-position automatic wire filling and TIG welding method for a steel pipe, and belongs to the technical field of welding. The all-position automatic wire filling and TIG welding method for the steel pipe comprises the steps that a groove is formed in the butt joint position of two steel pipes; and a TIG welding gun rotates around the butt joint position of the two steel pipes, performs all-position welding on the butt joint position of the two steel pipes, and welds the butt joint position of the two steel pipes. The all-position automatic wire filling and TIG welding method for the steel pipe can perform TIG welding on the steel pipe which cannot rotate, so that the welding efficiency is improved while the quality of single-face welding and double-face forming of the steel pipe is ensured, and the welding cost is reduced. 本发明公开了一种钢管的全位置自动填丝TIG焊方法，属于焊接技术领域。所述钢管的全位置自动填丝TIG焊方法包括：在两个钢管的对接处开设坡口；TIG焊枪绕两个所述钢管对接处进行旋转，对两个所述钢管的对接处进行全位置焊接，对两个钢管的对接处进行焊接。本发明钢管的全位置自动填丝TIG焊方法可以对不能旋转的钢管进行TIG焊，在保
