refractory metal-faced electrodes
HOSO’s copper-tungsten, silver tungsten, molybdenum and TZM-faced tips listed here withstand greater heat and pressure, at the expense of some conductivity. 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.
HOSO 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.
