6×8窄间隙焊机是我厂80年代从意大利引进的一种多功能自动焊接设备,适用于压力容器的简身<6m的内外环缝及8m纵键的埋弧焊接,配上堆焊的机头,可以对容器的内表面进行堆焊。原设备控制复杂、结构繁琐,功能齐全却不能完全被利用;报警系统过于灵敏,维修不便;机头导电性能不好,更换困难,经常处于瘫痪状态,一直闲置未用。1998年底,我们对该设备进行了改造,利用原有的机械结构,采用ESAB A6控制系统和自动跟踪系统,结合OMRON PLC控制系统及ESAB LAE1600焊
6 × 8 narrow gap welder is a kind of multi-function automatic welding equipment imported from Italy in 1980s. It is suitable for the <6m internal and external ring joints of pressure vessels and submerged arc welding of 8m longitudinal key, Of the nose, you can surfacing the inner surface of the container. The original equipment control complex, complicated structure, complete functions but can not be fully utilized; alarm system is too sensitive, inconvenient maintenance; poor head conductivity, replacement difficult, often in a paralyzed state, has been idle unused. The end of 1998, we have carried out the transformation of the equipment, the use of the original mechanical structure, the use of ESAB A6 control system and automatic tracking system, combined with OMRON PLC control system and ESAB LAE1600 welding
