This standard describes manual, semiautomatic, and automatic field welding by the metal arc-welding processes for stainless-steel potable water, wastewater, and reclaimed water pipe manufactured in accordance with ANSI\/AWWA C220. This standard describes field welding of two types of circumferential pipe joints: lap joints and butt joints. This standard also applies to other welding required in field fabrication and installation of specials and appurtenances. When possible, fabrications should be performed by the manufacturer at a manufacturing facility. The design of field-welded joints is not within the scope of this standard. This standard recognizes AWS D1.6\/D1.6M as the supporting document that provides more specific information except as noted in this standard. This standard can be referenced in documents for field welding of stainlesssteel potable water, wastewater, and reclaimed water pipe. The stipulations of this standard apply when this document has been referenced and then only to field welding of stainless-steel pipe.<\/p>\n
