摘要
选用同种焊条,采用相同的中心试块、引弧板做完消氢处理后,在相同的焊接参数下,采用熔敷金属扩散氢热导测量法,收集全国10个具备扩散氢含量检测资质检测中心的检测数据进行分析比较,利用Z比分数法对实验数据进行评定。
The labs of 10 qualified detection and measurement centers used a thermal conductivity detecting method to measure the content of diffused hydrogen in the deposited metal that has been welded on the same center test blocks and act plates with same electrodes and welding parameters and subjected to dehydrogenation heat treatment. Their results were analyzed and compared by the means of Z-score analysis to evaluate the test results.
