金属材料焊接的破坏性试验 硬度试验 第1部分：弧焊接头的硬度试验

[中文适用范围]： 本标准规定了焊接接头的硬度试验方法。 本标准适用于金属材料的电弧焊接头，其他接头种类(如压焊接头和堆焊金属)的硬度测试亦可参 照本标准实行。 本标准不适用于奥氏体不锈钢焊缝的硬度试验。 [外文原描述]： This part of ISO 9015 specifies hardness tests on transverse sections of arc welded joints of metallic materials. It covers Vickers hardness tests in accordance with ISO 6507-1, normally with test loads of 49,03 N or 98,07 N (HV 5 or HV 10). However, the principles may be applied to Brinell hardness testing (with appropriate testing loads of HB 2,5/15,625 or HB 1/2,5) in accordance with ISO 6506-1 and micro hardness testing in accordance with ISO 6507-1 and ISO 9015-2. NOTE Testing should be carried out to ensure that the highest and the lowest level of hardness of both parent metal and weld metal is determined. This part of ISO 9015 does not apply to test welds in austenitic stainless steels.
