针对薄板焊缝中的条渣缺陷的 X射线检测的可靠性问题进行了研究 ,通过试验发现 ,利用补偿泥制作模拟试板 ,使用铜丝模拟条状夹渣进行试验是完全可行的。分析了模拟缺陷和真实条渣的区别 ,并给出了试验条件下可检测的最短条渣的长度
The reliability of X-ray detection of slab defects in sheet metal welds was studied. It was found through experiments that it was feasible to make simulated test plates by using compensatory mud and simulate strip-shaped slag with copper wire. The difference between the simulated defects and the real slags is analyzed and the length of the shortest slags detectable under the test conditions is given
