Manufacturers using inverter technology in seam welding have reported decreased production throughput, reduced weld quality, and increased maintenance.
A number of factors contribute to resistance welding inconsistency, including: Inconsistent heat control Electrode force variations Part geometry/contact area variations Material hardness variations Oil on the part Other surface condition variations Conventional controls that apply the same heat regardless of what combination of prevailing conditions exists, result in inconsistent welds. When variations are severe enough, […]
Adaptive control regulates consistency of flash weld process while reducing power consumption. Most flash welding operations have high scrap rates and and power consumption due to the complexity and demands of the application. WeldComputer(R) inverter controls reduce energy demands, while providing for more precise flashing control. By adding monitoring and adaptive capabilities, flashing distance and upset […]
Benefits include regulating weld consistency, operating at fast production speeds, and improving weld quality By Robert K. Cohen Making a gas-tight seal with a seam welding machine involves making a series of overlapping spots. Each spot produced should be a fully formed nugget that is free of expulsion. Using too little heat produces an undersized spot, which can cause a leak. Using too much […]
