本文件规定了初步焊接工艺规范（pWPS）如何通过焊接工艺试验进行鉴定。 本文件适用于生产焊接、补焊和堆焊。 本文件规定了焊接工艺试验的执行条件和本文件资格范围内所有实际焊接操作的焊接工艺资格范围。 本文件适用于锻铝和铸铝及其合金的电弧焊。在本文件中，术语铝代表铝和铝合金。 本文件不适用于铝铸件的精加工焊接，这在ISO 15614-4中有规定。 根据ISO 4063:2023，铝的电弧焊包含以下焊接工艺: 131-使用实心焊丝电极的MIG焊接； 141-使用固体填充材料(线材/棒材)的TIG焊接； 142-自生TIG焊接； 15-等离子弧焊。

This document specifies how a preliminary welding procedure specification (pWPS) is qualified by welding procedure tests. This document applies to production welding, repair welding and build-up welding. This document defines the conditions for the execution of welding procedure tests and the range of qualification for welding procedures for all practical welding operations within the qualification of this document. This document applies to the arc welding of wrought and cast aluminium and its alloys. In this document the term aluminium stands for aluminium and for aluminium alloys. This document does not apply to finishing welding of aluminium castings, which is addressed in ISO 15614-4. Arc welding of aluminium is covered by the following welding processes in accordance with ISO 4063:2023: 131 — MIG welding with solid wire electrode; 141 — TIG welding with solid filler material (wire/rod); 142 — Autogenous TIG welding; 15 — plasma arc welding.
