DIN EN ISO 15614-7-2007 金属材料焊接程序的规范和鉴定.焊接程序试验.第7部分:覆盖焊接(ISO 15614-7:2007)
Specification and qualification of welding procedures for metallic materials - Welding procedure test - Part 7: Overlay welding (ISO 15614-7:2007); English version of DIN EN ISO 15614-7:2007-09
This part of ISO 15614 specifies how a preliminary welding procedure specification for overlay welding is
qualified by welding procedure tests.
This part of ISO 15614 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.
This part of ISO 15614 applies to all welding processes suitable for overlay welding.
This part of ISO 15614 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 this part of ISO 15614.
This part of ISO 15614 does not apply to overlay welding where cracks are intentionally produced (e.g. special
hardfacing applications).
