ASME V中规定超声波试块热处理要求如下:
T-434.1.5 Heat Treatment. The calibration block shall receive at least the minimum tempering treatment
required by the material specification for the type and grade. If the calibration block contains welds other than
cladding, and the component weld at the time of the examination has been heat treated, the block shall receive
the same heat treatment. 如何理解?
假设我们用的SA 516 Gr.70材质38厚的非管焊缝校验试块,没经过正火处理。而检测产品需要热处理后检测,我们的试块需要热处理吗?
