Better Welds And Longer Electrode Life Copper Tungsten Electrodes For Spot Welding Of Wire Harnesses
Descriptions:
Our unique non-defective bonding (NDB) technology creates a copper tungsten electrode that provides the desired levels of thermal conductivity while reducing wear and increasing electrode life. The result is optimal productivity and weld quality for your electrode applications.
Our copper tungsten electrodes resist cracking and offer superior performance for resistance spot welding.
Compared with electrodes using alloys such as chromium copper, testing shows that our copper tungsten electrodes exhibit excellent hardness at high temperature and minimal alloy formation. The results are improved performance without deformation of the electrode or adhesion to the workpiece.
Our copper tungsten electrode design and construction not only utilizes the proper composition and correct tip and shank profiles, but also take advantage of our NDB bonding method in electrode manufacturing, to ensure high thermal conductivity and stable bond quality.
As compared with conventional brazing and press fitting, this NBD process creates a bonding area ratio of almost 100%. This high-quality bonding results in electrodes that offer superior cooling performance after the welding stops, which in turn increases shot cycles and production efficiency. Depending on welding conditions, our NDB method results in electrodes that can achieve up to a ten-fold increase in electrode life.
