标准摘要
[中文适用范围]： ISO 15614 的这一部分规定了如何通过熔焊工艺测试来鉴定非合金和低合金铸铁的生产和修补焊接的初步焊接工艺规范（pWPS）。 ISO 15614 的这一部分定义了焊接工艺测试的执行条件以及在定义的变量列表范围内所有实际焊接操作的焊接工艺资格范围。 ISO 15614 的这一部分适用于所有新的焊接工艺。 然而，它并不会使之前根据以前的国家标准或规范进行的焊接工艺测试无效。 如果必须进行附加测试以使鉴定在技术上等效，则只需对按照 ISO 15614 本部分制作的试件进行附加测试。 应用标准可能要求附加测试。 ISO 15614 的本部分适用于焊接非合金和低合金灰铸铁铸件，符合： EN 1561； EN 1562； EN 1563； EN 1564。 ISO 15614 本部分的原则也适用于铸铁与钢或其他非合金和低合金铸铁材料的焊接。 [外文原描述]： ISO 15614-3:2008 specifies how a preliminary welding procedure specification (pWPS) for production and repair welding of non-alloyed and low-alloyed cast irons is qualified by fusion welding procedure tests. ISO 15614-3:2008 defines the conditions for execution of the welding procedure tests and the range of qualification for welding procedures for all practical welding operations within the range of a defined list of variables. ISO 15614-3:2008 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 have to be carried out to make the qualification technically equivalent, it is only necessary to do the additional tests on a test piece made in accordance with ISO 15614-3:2008. Additional tests may be required by application standards. ISO 15614-3:2008 is applicable to welding non-alloyed and low-alloyed grey cast iron castings according to: EN 1561; EN 1562; EN 1563; and EN 1564. The principles of ISO 15614-3:2008 are also applicable for welding cast iron to steel or to other unalloyed and low-alloyed cast iron materials.
