焊缝射线探伤用于造船工业、机械制造工业以及其他一些工业,已有相当长的时间,解决了不少问题,也发现了许多不允许存在的缺陷。经过几年来的实践,对造船事业也起了相当大的促进。但是,对于焊缝射线检验质量标准与抽查率存在比较多的问题,各方面意见比较集中,矛盾比较尖锐。原来的质量验收标准和抽查率已经远远不能适应工业生产新高潮的形势。为此,有必要作讲一步的研究与调整,这是我 Weld ray tracing has been used for a long time in the shipbuilding industry, the machinery manufacturing industry and some other industries to solve many problems and to discover many imperfections that may not exist. After several years of practice, the shipbuilding industry has played a considerable boost. However, there are many problems with the quality standard and spot check rate of the weld ray inspection, and the opinions of all parties are more concentrated and the contradictions are rather sharp. The original quality inspection standards and the sampling rate have been far unable to meet the new peak of industrial production situation. To this end, it is necessary to make further study and adjustment, this is me
