本标准描述了根据AWWA C220制造的不锈钢饮用水、废水和再生水管的手动、半自动和自动现场金属弧焊焊接工艺。本标准描述了两种环形管接头的现场焊接:搭接接头和对接接头。本标准也适用于现场制造和安装特殊设备和附件所需的其他焊接。如果可能，制造商应在制造工厂进行制造。现场焊接接头的设计不在本标准的范围内。本标准认可AWS D1。6/D1。6M作为支持文件，提供了除本标准另有说明外的更多具体信息。本标准是本标准的第一版，因此没有重大修订。

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 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. The is the first edition of this standard, and therefore, there are no major revisions.
