Tungsten& molybdenum for micro spot weldingMicro spot welding electrode is a kind of precision resistance spot welding electrode. Compared with the traditional tungsten molybdenum electrode on the market, our electrode has excellent high temperature stability and longer service life.
Our micro spot welding electrodes (micro spot welding head, micro spot welding needle, PCB repair welding head, hot pressing welding head, etc.) are made of pure tungsten, pure molybdenum and their alloy materials with stable quality. Each electrode is deeply densified and has a higher density and more uniform internal organization structure. They are applied to the precision electronic spot welding industry, and can be applied to all kinds of micro motor coils and precious metals The connection of various leads of coils and microelectronics and the welding of the contact of various micro copper coil electronic components.
Advantages of Hengmi micro spot welding：
1. Each of our electrodes has been densified, with relatively high density and uniform internal structure, which can maintain constant resistance and stable conductivity.
2. The back cast electrode adopts NDB (non defective bonding) technology, without pores, and the connection strength is more than 130 MPa; it realizes the integration of copper, tungsten and molybdenum refractory metals, and the combination degree is close to 100%.
3. 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;
4. Combined 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 in combination with the actual situation of customers.
