水压试验是焊接与铸造生产中一道常用的工序,以它来检验受压件的强度和密封性。多年来,我们逐步地用“非焊接堵板”取代“焊接堵板”来进行水压试验收到了较好的成效。一、非焊接水压堵板的夹紧方式有两种: 1.靠外力夹紧(利用试压机); Water pressure test is a commonly used process in the welding and casting production, with which to test the strength and sealing of the pressure. Over the years, we have been progressively using “non-welding block board” instead of “welding block board” to carry out hydrostatic test received good results. First, non-welding hydraulic blocking plate clamping in two ways: 1. By external force clamping (using the test press);
