Design of Automatic Welding Device for Nuclear Vessel Head

Nuclear materials container is strongly radioactive due to the radioactive content inside,and before the storage and transportation,the vessel head and body shall be tightly welded.To improve the welding quality and reduce the radiological dose that workers expose,an automatic welding device is developed based on MIG welding and OTC robot system.This device is safe and with high stability,and automatic welding on complex surface can be achieved with remote programming control.
