摘要
对44mm厚的CF—62钢宽板和窗形拘束板焊缝的残余应力测试的结果基本代表了球罐的实际焊接残余应力状况,同时通过对宽板和窗形拘束板各种状态下焊接残余应力测试表明,焊缝余高打磨、预加载等措施对降低焊接残余应力都有一定作用,而热处理的效 果相对较好。
This paper describes the vvelding residual stress determination on CF-62 steel plate with a thickness of 44mm,the results showed that the reinforcement grinding, pre-loading and heat treat ment had good effect on welding residual stress reduction.
