ABSTRACT:
A method for butt welding pipe sections together wherein each pipe section has a beveled end includes positioning the pipe sections adjacent one another so that the beveled ends define a weld groove and locating filler material of elongate dimension having a triangular cross-section so that an edge portion thereof protrudes through the weld groove. The filler material is fused to the weld groove by striking an inert gas-shielded arc between a Heliarc torch electrode and the beveled ends and advancing the electrode relative to the filler material so that a weld bead is formed having a convex profile on the interior surfaces of the pipe sections adjacent the weld groove.
