一、概述焊接对压力容器制造来说,起着决定性的作用。那么如何来验证焊接产品接头的性能呢?目前世界各国通常的做法是通过产品见证件的破坏性试验来验证施工工艺的稳定性及焊接接头机械性能的可靠性。在破坏性试验检测过程中,通过弯曲(面弯、背弯或侧弯)试验来检验熔敷金属及热 First, an overview of the welding pressure vessel manufacturing, plays a decisive role. So how to verify the performance of welded joint it? Common practice in the world is to verify the stability of the construction process and the reliability of the mechanical properties of welded joints through the destructive test of the product witness. During the destructive test, the deposited metal and heat were tested by bending (bending, buckling or bending) tests
