Cryogenics Processing Cryogenic treatment greatly improves the wear resistance and life expectancy of copper alloy resistance welding electrodes. Resistance to deformation is also greatly enhanced, and less input power is required to operate the weld operation. Another great benefit is that tip burn-off is greatly reduced. The typical mode of failure for welding electrodes is thermal cyclic fatigue. The part is heated and cooled many times which causes cracks to form. The cracks then propagate and the surface starts to collapse. This changes the surface area which throws off the welding parameters and the part starts to fail rapidly. Cryogenic processing delays the initial cracking and reduces the resistivity of the part. The increased life reduces welding costs and increases profits. It also improves the quality of the weld. What can you expect from cryogenic processing? Documented test cases show at least a 100% (minimum) life expectancy increase for copper alloy electrodes, but many users report a 300% life increase.
There are several other areas in the welding field to consider. First, and the most obvious, are weldments themselves. Cryogenic Processing removes weld stress and deadens the pulling and tugging that accompany the welding process. Other areas for welders are the wire guides, wire tubes, and nozzles on wire feed welding machines. The nozzles wear longer and better. Plasma cutting equipment tips and nozzles are great candidates for increased wear. Laser cutting nozzles and water jet nozzles are being studied, but proven results have already been seen in sand blasting nozzles, pressure washer nozzles, and paint and powder coating nozzles last longer once processed. Electrical contacts also benefit from cryogenic. They can carry more current, and lose less live on make or break. Relays and circuit breakers are prime beneficiaries to this technology.
