scope:

This standard describes 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 describes field welding of three types of circumferential pipe joints: (1) lap joints; (2) butt joints; and (3) 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 described.

This standard recognizes ANSI/AWS D1.1 as the supporting document that provides more specific information. Welding of gasketed joints may require modification to the parameters of this welding standard.
