NDB 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.
