为改善焊工培训中焊件的测试手段,我们自制了焊件弯曲和断口检验试验装置。此装置通过在我厂焊工的实际操作考核中的应用,证明试验效果良好。这套装置不仅适用于缺乏试验设备的中小企业,而且通过它还能解决拉力试验机上不易解决的难题如:较大管件的夹持问题。下面就将试验方法及使用情况介绍如下: In order to improve the testing methods of welder in welder training, we made a self-made welder bending and fracture testing device. This device through the actual operation of our welder in the assessment of the application to prove that the test results are good. The device is not only suitable for small and medium-sized enterprises that lack test equipment, but also solves the difficult problems that are difficult to solve in the tensile testing machine, such as the problem of gripping the larger pipe. The following will test methods and the use of the introduction are as follows:
