标准摘要
[中文适用范围]： 本文件规定了如何通过焊接工艺试验（pWPS）来验证预焊接工艺规程的合格性。本文件指定了执行焊接工艺试验的条件和范围，以覆盖第8条列出的所有变量范围内实际焊接操作的焊接程序资格。本文件指定了所需的试验项目。附加试验可能由应用标准要求。本文件适用于所有产品形式的钛、锆及其合金的电弧焊。根据ISO 4063：131 - 金属惰性气体焊接，MIG焊接；14 - 钨惰性气体焊接，TIG焊接；15 - 气体切割焊接。本文件的原则可以应用于其他熔化焊接工艺。 [外文原描述]： This document specifies how a preliminary welding procedure specification (pWPS) is qualified by welding procedure tests. This document specifies the conditions for the execution of welding procedure tests and the qualification range for welding procedures for all practical welding operations within the range of variables listed in Clause 8. This document specifies the required tests. Additional tests can be required by application standards. This document applies to the arc welding of titanium, zirconium and their alloys in all product forms. Arc welding is covered by the following processes in accordance with ISO 4063: 131 – metal inert gas welding, MIG welding; 14 – tungsten inert gas welding, TIG welding; 15 – plasma arc welding. The principles of this document can be applied to other fusion welding processes.
