NDB Tungsten Molybdenum Resistance Spot Welding Electrode
NDB (non-defective bonding) electrodes are created using a high-vacuum bonding technique that forms a seamless joint—no filler materials, no voids, no weak points. Using copper, CuCrZr as shaft, tungsten, molybdenum, WLa, TZM etc as tips. This method produces a highly conductive, ultra-strong bond with tensile strength > 120MPa.

Key Features & Customer Benefits of W Mo Resistance Spot Welding Electrode
Why Our Tungsten Molybdenum Electrodes Stand Out？
Seamless NDB Bonding
No additional welding materials are required. Tungsten, Molybdenum and realted alloy tips are seamlessly fused into Copper and related alloy with no internal pores. With a bonding strength above 130 MPa, the connection ensures the resistance spot welding electrode have excellent conductivity and thermal performance, significantly extending service life and reducing energy loss.
High-Quality Materials & Stability
Electrodes are manufactured using carefully selected, high-quality raw materials with excellent physical and chemical stability. With the addition of rare elements, the electrodes achieve enhanced thermal stability, outstanding resistance to deformation, hardness loss, and oxidation, ensuring long-lasting reliability without cracking or delamination.
Superior Structural Integrity
Each electrode undergoes thorough densification treatment, resulting in high density and uniform internal structure.
Wide Material Compatibility
Ideal for tungsten, molybdenum, stainless steel, and alloys like Inconel and nichrome.
Extensive Industry Expertise
With years of experience in resistance welding electrode production, we provide customized design improvements tailored to customer needs and real-world applications.
