This document provides a preliminary welding procedure specification (WPS) for welding pipe. It specifies TIG welding for the root pass and MMA welding for the fill and cap passes. The WPS qualifies butt joints in pipe using filler metals ER70S-6 and E7018-1 for welding ASTM A333 Grade 6 pipe that is 10.97 mm thick with an outside diameter of 168.3 mm. The WPS is applicable for welding in the horizontal-fixed position.
