湿式煤气柜裂缝的不停产焊补

Fissure's Welding of Wet Gas-Box under Production

介绍应用挂塔补焊技术修理湿式煤气柜的原理和方法．为了在保证生产的条件下，修补裂缝的煤气柜，首先将两个煤气柜用连杆联在一起，然后用蒸汽或压缩空气把水封槽内的残余煤气吹扫干净，最后进行直接焊接．这一技术简化了煤气柜焊接的工序，改善了操作者的工作条件，消除了火灾隐患，并且提高了煤气柜的生产能力．

The principle and procedure of repairing wet gas box by using connecting rod welding were described. In order to repair gasbox fissured under production,two gas-box were jointed with connecting rods, sandwich gas in water seal trough was blow off with vapor or compressed air, then welding was carried out directly. The technique simplifies working process of gas-box welding, improves working condition of operators, eliminates danger from fire, and increases production capacity of gas-box.
