高频焊钢管焊缝冲击试验问题探讨

Discussion on Weld Impact Test of High Frequency Welded Pipe

为提升高频焊钢管产品质量,保证焊管冲击试验测量结果的准确性非常重要。在实际检测过程中,因高频焊缝经热处理后是一条宽度不到0.3 mm的细线,因此要保证得到准确的冲击试验结果存在一定困难。通过对高频焊钢管焊缝冲击试验中试样的准备、焊缝腐蚀、小尺寸试样以及试验机等多方面影响冲击试验结果问题探讨,找到了相应的解决方案,从而保证了冲击试验结果准确性。

In order to improve the HFW pipe product quality, ensure the measurement results accuracy of the welded pipe impact test is very important. In the process of the actual detection, due to the high frequency weld is a thin line with width less than 0.3 mm after heat treatment, so make sure the exact impact test result has certain difficulty. Some problems affecting impact test result were discussed, including the preparation of impact test sample, weld corrosion, small size test sample, testing machine and so on. And give the relevant solutions, thus the accuracy of impact test result can be ensured.
