Abstract
This paper introduces the measure, welding method and inspection result to preve nt the welding deformation formation of spiral-seam pipe header after tapping. The author considers that to prevent the deformation and ensure the welding quality, to rationally determine the tapping location and avoid the holes upon the spiral seam is important.
