为了蒸发器管子腐蚀的返修开发了一种使用机器人和CO_2激光的新的焊接方法,与其它溶化焊方法相比,它能适应更宽的温度范围和几何形状,并且在比利时的许多核动力工厂已经成功地得到了证实。早期蒸发器返修主要是剥蚀管子的赌塞,这最终将导致降低发电厂的效益或者更换整台蒸发器。套管是在原来的管子内插入一根新的管子,并且在已腐蚀的管子上、下 For reworking evaporator tube corrosion, a new welding method using robots and CO 2 lasers has been developed that accommodates a wider temperature range and geometry than many other melt welding methods and has been used in many nuclear power plants in Belgium Has been successfully confirmed. Early evaporator rework is mainly denudation of pipe gambling, which will eventually lead to reduced power plant efficiency or replace the entire evaporator. The sleeve is inserted in the original tube a new tube, and in the corrosion of the tube, the next
