Research and application of welding technology of copper tube for nuclear power test device
Copper tube has excellent conductivity and corrosion resistance,and has become the preferred material for AC and DC power supply system.The installation and welding method of thick-walled copper tube(T2)for power supply was analyzed by simulating the electric heating rod of nuclear power test device in the paper,and evaluated the quality of welding process through physical and chemical tests and resistivity tests,and the evaluation results were all qualified,and the butt joint of copper tube had good strength,plasticity and conductivity.The related MIG welding could provide a reference for similar thick-walled copper and copper alloy pipe welding.
