本文件提供了2G高温超导连接程序的概念、规范和鉴定。焊接工艺规范（WPS）需要为计划连接操作和连接期间的质量控制提供依据。在质量体系标准术语中，连接被视为一个特殊过程。质量体系标准通常要求按照书面程序规范执行特殊过程。这导致在将WPS发布到实际生产之前，建立了一套连接程序鉴定规则。本文件定义了这些规则。 本文件不包括焊接、硬钎焊或任何填料，这些材料目前在行业中可用。 适用于各种2G高温超导的连接。 本文件不适用于第一代铋锶钙铜氧化物（1G BSCCO）型高温超导和低温超导（LTS）连接。

This document provides concepts, specification and qualification of 2G HTS joining procedure. A welding procedure specification (WPS) is needed to provide a basis for planning joining operations and for quality control during joining. Joining is considered as a special process in the terminology of standards for quality systems. Standards for quality systems usually require that special processes be carried out in accordance with written procedure specifications. This has resulted in the establishment of a set of rules for qualification of the joining procedure prior to the release of the WPS to actual production. This document defines these rules. This document does not cover soldering, brazing or any fillers, which are currently available in the industry. It can be applied for joining of all kinds of 2G HTSs. This document does not apply to 1st Generation Bismuth Strontium Calcium Copper Oxide (1G BSCCO) type HTS and Low Temperature Superconductor (LTS) Joining.
