【摘要】 工业锅炉(或其他换热设备)的受压元件,由于受腐蚀而使强度下降,导致被判废或降压使用,造成极大浪费。在受压元件受约束或不能随意施焊的情况下,不允许立即在生产设备上进行修补。本文在相同的模拟设备上,采用电测应变法确定安全修复的焊接施工规范,对两台被判废的锅炉进行修复使用,为企业节省大量投资。实践证明这种方法是可行的。更多还原

【Abstract】 In repairing a boiler welding, it is very important to determine the proper welding condition to prevent the boiler from overheating and expanding, in order to maintain the performance of the expansion joints between the boiler drum and tubes.In this paper a series of resistance strain measurements have been done, and an easy, suitable welding code is determined successfully.更多还原
