Describe
Refractory metal-faced electrodes
Besides being used for spot welding high resistance base metals, they are useful in achieving “heat balance” when welding dissimilar metals. We can make the standard one with taper and shank, also we can make the electrode per customer’s drawing.
JBNR bonding technology:
1) Silver brazing. Advantage: fast join, flexible and no limit for different shape. Disadvantage: silver is expensive; handle by experienced worker otherwise it is easily has gap or porosity between shank and refractory metal face.
2) Back shank casting: very good heat transfer and strengthen between the shank and refractory metal face.
Product:
1: copper tungsten (10W3) faced nut welding electrode and cover (used for automotive industrial, lots of sheet and work piece need be connected by the nut. also used for wire mesh welder)
2: silver tungsten faced resistance welding electrode for low resistance welding.
