金属材料焊接程序的规范和鉴定.焊接程序试验.第1部分:钢的电弧焊和气焊及镍和镍合金的电弧焊

[中文适用范围]： 本文件规定了如何通过焊接程序试验对初步焊接工艺规程进行资格鉴定。本文件适用于生产焊接、修复焊接和堆焊。本文件定义了执行焊接程序试验的条件以及在本文件规定的资格范围内所有实际焊接操作中焊接工艺的适用范围。焊接程序双重认证的主要目的是证明拟用于结构中的连接过程能够产生具有所需机械性能的接头。本标准分为两个级别，一级和二级，以适应更广泛的应用范围。二级的测试范围比一级更为广泛，且资格范围也更为严格。达到二级要求的程序试验自动符合一级要求，但反之则不成立。如果合同或应用标准中未指定级别，则所有二级的要求均适用。本文件适用于各种形式的钢的电弧焊和气体保护焊，以及各种形式的镍及其合金的电弧焊。根据ISO 4063规定的以下工艺：111 - 手工金属极焊接（带覆盖层的电极金属-电弧 welding）；114 - 自屏蔽管状芯部电弧 welding；12 - 埋弧 welding；13 - 气体保护金属电弧 welding；14 - 使用非消耗性电极的气体保护电弧 welding；15 - 等离子电弧 welding；311 - 氧乙炔 welding。本文件的基本原则也可应用于其他融合焊接工艺。注：以前的工艺编号不需根据本文件要求进行新的资格鉴定试验。根据本文件先前版本制定和鉴定的焊接程序规范可用于本文件规定为当前版本的任何应用。在这种情况下，先前版本的资格范围仍然适用。 [外文原描述]： ISO 15614-1:2017 specifies how a preliminary welding procedure specification is qualified by welding procedure tests. ISO 15614-1:2017 applies to production welding, repair welding and build-up welding. ISO 15614-1:2017 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. The primary purpose of welding procedure qualification is to demonstrate that the joining process proposed for construction is capable of producing joints having the required mechanical properties for the intended application. Two levels of welding procedure tests are given in order to permit application to a wide range of welded fabrication. They are designated by levels 1 and 2. In level 2, the extent of testing is greater and the ranges of qualification are more restrictive than in level 1. Procedure tests carried out to level 2 automatically qualify for level 1 requirements, but not vice-versa. When no level is specified in a contract or application standard, all the requirements of level 2 apply. This document applies to the arc and gas welding of steels in all product forms and the arc welding of nickel and nickel alloys in all product forms. Arc and gas welding are covered by the following processes in accordance with ISO 4063. 111 - manual metal arc welding (metal-arc welding with covered electrode); 114 - self-shielded tubular-cored arc welding; 12 - submerged arc welding; 13 - gas-shielded metal arc welding; 14 - gas-shielded arc welding with non-consumable electrode; 15 - plasma arc welding; 311 - oxy-acetylene welding. The principles of this document may be applied to other fusion welding processes. NOTE A former process number does not require a new qualification test according to this document. Specification and qualification of welding procedures that were made in accordance with previous editions of this document may be used for any application for which the current edition is specified. In this case, the ranges of qualification of previous editions remain applicable. It is also possible to create a new WPQR (welding procedure qualification record) range of qualification according to this edition based on the existing qualified WPQR, provided the technical intent of the testing requirements of this document has been satisfied. Where additional tests have to be carried out to make the qualification technically equivalent, it is only necessary to perform the additional test on a test piece.
