This standard covers manual, semiautomatic, and automatic field welding by the metal arc-welding processes for steel water pipe manufactured in accordance with ANSI/AWWA C200, Standard for Steel Water Pipe--6 In. (150 mm) and Larger. This standard covers field welding of three types of circumferential pipe joints; lap joints, butt joints, and butt-strap joints. Other welding required in field fabrication and installation of specials and appurtenances is also discussed. The design of field welded joints is not covered. This standard recognizes ANSI/AWS D1.1 and ANSI/ASME Sec. V as supporting documents that provide more specific information. Welding of gasketed joints may require modification to the parameters of this welding standard. The major revisions to the standard in this edition include: the format has been changed to AWWA standard style; Sec. 1.1, Scope, was expanded, and Sec. 1.2, Purpose, and Sec. 1.3, Application, were added; Sec. 4.6.5.
