Tungsten and Molybdenum Inserted Electrodes for Resistance Welding

Description of Resistance Welding:

Resistance welding is a process in which metals are joined together by adding pressure and heat caused by electric current. There are various resistance welding types: Resistance spot welding, resistance seam welding, resistance projection welding, resistance butt welding and flash butt welding.

Resistance Welding Advangtages: 

By using resistance welding, there are lots of advantages like cost effective, highly automated, and high production rate and high welding rate. So now this method of welding is widely supported.

Resistance Welding Electrodes Material:

Welding electrodes made of tungsten, molybdenum, and their alloys perform well when welding high conductive materials such as copper. Refractory metals have high melting point and they have high temperature strength, high hardness, good creep resistance and relatively low coefficient of expansion.

NDB to Cast Resistance Welding Electrodes:

Our material is produced with very homogeneous structure and this fine and uniform grain structure and ensure its properties to the best.

For refractory metal and copper shank combination, we use NDB technology—back casting to achieve 100% combination between these two different materials.

We have been producing resistance welding electrodes for years. We can design electrodes for your application once you tell us your materials and welding situation.

Materials we can produce:

Pure tungsten, Tungsten lanthanum, Pure molybdenum, TZM, Tungsten copper, Tungsten heavy metal. Shaft can be made of CuCrZr, Cu and also Beryllium copper.
