DIN EN ISO 15614-6-2007 金属材料焊接程序的规范和鉴定.焊接程序试验.第6部分:铜及其合金的电弧焊接和气焊(ISO 15614-6-2006)
Specification and qualification of welding procedures for metallic materials - Welding procedure test - Part 6: Arc and gas welding of copper and its alloys (ISO 15614-6:2006); English version of DIN EN ISO 15614-6:2007-01
This part of ISO 15614 specifies how a preliminary welding procedure specification is qualified by weldii procedure tests. It applies to the arc and gas welding of copper and copper alloys in all product forms.
This part of ISO 15614 defines the conditions for the execution of welding procedure tests and the range qualification for welding procedures for all practical welding operations within the range of variables listed Clause 9.
This part of ISO 15614 is applicable to all new welding procedures. However, it does not invalidate previot welding procedure tests made to former national standards or specifications. Where additional tests have be carried out to make the qualification technically equivalent, it is only necessary to do the additional tests c a test piece made in accordance with this part of ISO 15614.
Additional tests may be required by application standards. The principles of this part of ISO 15614 may be applied to other fusion welding processes.
