Spot welding tungsten barCombined with many years of experience in the production and processing of resistance welding electrodes, the site of resistance welding can be understood, and the improved design scheme can be provided based on the actual situation of customers.
Each of our electrodes has been densified, with relatively high density and uniform internal structure, which can maintain constant resistance and stable conductivity.
Using the special formula materials for resistance welding, the raw materials with stable quality, giving full play to the physical characteristics of high melting point of tungsten, adding rare earth elements, further optimizing the high temperature stability, creep resistance, high hardness, impact resistance, not easy to deform, no false welding, and solid solder joints;
