We manufacture tungsten back-cast CrZrCu, tungsten and molybdenum base electrodes for resistance spot welding, through NDB technology, which greatly improves the service life of resistance welding electrodes. The welding electrode shape and size could be customized.
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.
Yolo’s electrodes are widely used in mechanical manufacturing and welding technology. In the field of automobile parts, such as
Wire harness
Automobile motor
Switch contact
Ignition coil
Brake electronic system
Electromagnetic coil
Sensor lead wire
Welding copper strip
Copper braided wire contact
we provide professional welding consumables manufacturing solutions for customers from all over the world.
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

Raw materials & Machining Cost
Yolo, as a professional manufacturer of tungsten-base resistance welding electrode, you could save procurement costs from the source. Because we start production from raw material APT powder and meet Japanese and German market standards. But you will benefit a lot from the location of the factory, China.
Delivery on time
Complete order management system and rich production experience enables customer orders in an orderly manner. Our annual customer complaint rate is less than 1%.
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.
The new resistance welding electrode with NDB technology from YOLO, back-cast with copper and tungsten copper.
Extended service life and better performance
Improved, reproducible spot welding quality
Efficient and cost-effective part production
We not only combine material properties but also their economic benefits.
