标准范围

ISO 15614-7:2007规定了堆焊的初步焊接工艺规范如何通过焊接工艺试验进行评定。ISO 15614-7:2007定义了第8条所列变量范围内所有实际焊接操作的焊接工艺试验条件和焊接工艺评定范围。应用标准可能要求进行其他测试。ISO 15614-7:2007适用于所有适用于堆焊的焊接工艺。ISO 15614-7:2007适用于所有新的焊接工艺。然而，它不会使以前按照国家标准或规范进行的焊接工艺试验无效。如果进行附加试验以使鉴定在技术上等效，则仅在按照ISO 15614-7:2007制造的试件上进行。ISO 15614-7:2007不适用于有意产生裂纹的堆焊（例如特殊堆焊应用）。

ISO 15614-7:2007 specifies how a preliminary welding procedure specification for overlay welding is qualified by welding procedure tests.ISO 15614-7:2007 defines the conditions for carrying out welding procedure tests and the range of qualification for welding procedures for all practical welding operations within the range of variables listed in Clause 8.Additional tests may be required by application standards.ISO 15614-7:2007 applies to all welding processes suitable for overlay welding.ISO 15614-7:2007 is applicable to all new welding procedures. However, it does not invalidate previous welding procedure tests made to former national standards or specifications. Where additional tests are carried out to make the qualification technically equivalent, they are only done on a test piece made in accordance with ISO 15614-7:2007.ISO 15614-7:2007 does not apply to overlay welding where cracks are intentionally produced (e.g. special hardfacing applications).
