IAMU has developed a Model Gas Pipeline Welding Procedures Manual that contains thirteen qualified welding procedures that may be used on gas pipelines.  Welding procedures include in-service welding procedures, fillet welding procedures, side seam procedures, and butt-welding procedures for differing pipe sizes and wall thicknesses.
