NDB electrode&Back cast electrodeInlaid electrode is one of the resistance welding electrodes, which has stable conductivity, heat dissipation and other properties in some specific welding environments. Therefore, compared with the traditional electrodes (such as tungsten, molybdenum, copper and their alloy electrodes), the application effect is better.
Our production of resistance welding inlaid electrode (also called:Back cast electrode &NDB electrode&copper inlaid tungsten electrode&copper inlaid molybdenum electrode&copper inlaid tungsten alloy electrode&copper inlaid molybdenum alloy electrode&copper inlaid tungsten copper electrode, etc.) adopt pure tungsten, pure molybdenum and its alloy as the welding end, and the rod adopts chromium zirconium copper and oxygen-free copper. Different from ordinary electrodes, our inlaid electrodes are connected by NDB (non defective bonding) in a vacuum environment, also known as NDB welding electrode, which has stable conductivity and heat dissipation. The end of the electrode can be cooled continuously, reducing the heat load of the end electrode head, thus increasing the service life of the electrode and reducing the production cost.

Advantages of Hengmi NDB electrode:
1. Copper are integrated with tungsten&molybdenum refractory metals. NDB integrated connection process is adopted. No solder is added. There is no hole in the inner part. The connection strength is more than 130 MPa. It has excellent conductivity and thermal conductivity, so as to ensure that the electrode end can be continuously cooled, thus increasing service life and reducing electrode consumption.
2. The end of each electrode is densified and has high density and uniform internal structure.
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.
