covered by/ wash-blending(表面检验)什么意思? Surface Examination(表面检验): 1. Examination shall be done after completing all required postweld heat treatment, except weld surfaces which will become inaccessible by reason of welded closures which themselves require postweld heat treatment (e.g., nozzle-to-vessel welds covered by reinforcing pads) shall be examined before such closures are welded. ...... 所有要求的焊后热处理在完成后应进行检测,除了本身需要进行焊后热处理而由于焊接密封无法接近的焊缝表面(如被补强圈覆盖的接管至容器焊缝),应在这些密封面焊接之前进行检测。 3. When liquid penetrant examination is required, it shall be performed on all accessible weld surfaces. Any surface irregularities which interfere with the examination shall be removed by grinding, machining, or wash-blending with Gas Tungsten Arc Welding. 当需要进行液体渗透检测时,应对所有可以到达的焊缝表面进行渗透检测。所有影响检测的不规则表面应通过打磨、加工或混水钨电极惰性气体保护焊来清除。查看更多4个回答 . 5人已关注
