摘　　要：依据某核电与石化产品堆焊的主要特点与工艺流程,设计了基于DeviceNet总线的高性能PLC控制核心,并配备DeviceNet总线焊接电源、双钨极焊枪、触摸屏、伺服定位系统、弧压处理系统、自动焊接三维滑架等单元构成的双钨极堆焊成套设备。经过焊接工艺试验,验证了整套系统的可靠性、自动化程度、抗干扰能力、扩展性。焊缝成型良好,堆焊效率较单钨极提高1倍,UT探伤、焊缝化学成分、铁素体含量、弯曲性能、晶间腐蚀、硬度等检测项均合格。According to the main characteristics and technological process of surfacing welding of a nuclear power product. It is designed to a high performance PLC control system based on the Device Net Bus,which is equipped with digital welding power source,double tungsten electrode welding torch,touch screen,servo positioning control system,arc voltage high speed processing system,wireless automatic communication system,automatic welding three-dimensional slide frame and other elements of double tungsten electrode surfacing equipment. The field test shows that the system has strong the reliability,automation,anti-jamming ability and expansi-bility. The surfacing welding efficiency is 1 times higher than that of single tungsten electrode. These test items which are UT flaw detection,weld chemical composition,bending performance,intercrystalline corrosion,hardness,metallographic st-ructure and other detection items,are qualified.
