20、 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 but

21、t joints. This standard also applies to other welding required in field fabrication and installation of specials and appurtenances. When possible, fabrica- tions should be performed by the manufacturer at a manufacturing facility. The design of field-welded joints is not within the scope of this sta

22、ndard. This standard recognizes AWS* D1.6/D1.6M as the supporting document that provides more specific information except as noted in this standard. Sec. 1.2 Purpose The purpose of this standard is to provide minimum requirements for field welding and inspection of field welds on stainless-steel potable water, wastewater, and reclaimed water pipe. * American Welding Society, 550 Northwest LeJuene Road, Miami, FL 33126.
