重载条件下气压焊缝轨头伤损探测研究

Research on detection of railhead injuries of gas pressure welding under heavy loading condition

通过对现场气压焊的外观类型及伤损产生部位进行调查,分析了伤损的类型、取向,针对不同外观类型的气压焊、不同类型的轨头伤损,提出了利用JGT-10型探伤仪对气压焊缝轨头伤损的检测及判定方法,以供参考。

According to the investigation over the outline types of the gas pressure welding on site and their parts of injuries, the paper analyzes the types and orientation of the injuries, and points out JGT-10 flaw detector can detect the railhead injuries of the gas pressure welding and its detection methods according to the gas pressure welding with various outlooks and different railhead injuries, so as to provide some reference
