Details about Resistance Welding Electrode

Tungsten & Molybdenum Base

Welding Electrode Maker from China

Does your welding equipment need frequently replacing electrodes? Do you find that the thermal load on the electrode head is too large? Would you like an electrode with a longer life?

Also, does your electrode tip deform and wear out quickly? Does the contact area increases rapidly and the strength of the solder joint also decreases? These are tough questions, but important ones.

Some electrodes seem to help you save a lot of purchase costs, but frequent replacement of electrodes and reduced work efficiency have virtually increased your purchase costs.

Yolo, a professional electrode manufacturer for resistance welding from China, utilizing NDB technology satisfied customers all over the world. Now, please follow us to show you something, something we hope could help you.

What’s YOLO core Competitiveness?

NDB (non-defective bonding) Technology

NDB(Non-defective Bonding)

Tungsten back-cast Copper technology

Different from the common brazing process, YOLO uses NDB (non-defective bonding) to back-cast copper and copper alloys with tungsten and molybdenum refractory metals in the vacuum environment, which has stable conductivity and heat resistance. The end of the electrode can be continuously cooled, reducing the heat load of the end electrode head, so as to increase the service life of the electrode and reduce the production cost.

There are no pores, no holes, no gaps, and the connection strength is> 120Mpa. In addition, the electrode end has high machining accuracy and a smooth finish below Ra0.8, the welding joints are stable, no false welding occurs, and the joints are firm.

Different electrode materials – depending on the material to be welded:

WLa (wolfram-lanthanum alloy)
WCu (wolfram-copper alloy)
ZM (wolfram-copper alloy)
Pure Tungsten (99.95%)
Pure Molybdenum (99.95%)
CrZrCu back-cast tungsten
Copper back-cast molybdenum

What is the Resistance Welding?

Resistance Welding is to press the base materials together by pressure, and use a large current to pass through the plate contact surface to generate resistance heat. The temperature between the parts is higher than the workpiece’s melting point and forms a molten pool. Such operation needs to be performed under high current and strong pressure.

Especially welding thick sheets, the force between the electrode and the workpiece may be 450 MPa. It is a considerable challenge for welding electrodes that must withstand the force.
