In this presentation, WeldComputer Founder Bob Cohen explains how resistance welding operations can increase flash welding performance while reducing energy utilization. You will learn how to: increase the flashing capability of your machine, increase flashing consistency, increase upset consistency, provide proof of flashing and upset consistency of every weld, and reduce energy demand and flicker on the power line. […]
A manufacturer contacted us recently with a problem: Their welding performance looked good and their machine performing well. But each aluminum weld created had a dark spot that was noticeable. They were concerned about the impact this cosmetic defect was having on the appearance of their product, and the perception that it could be impacting […]
Manufacturers using inverter technology in seam welding have reported decreased production throughput, reduced weld quality, and increased maintenance.
Troy, NY – November 11, 2019 – WeldComputer Corporation is pleased to announce that Robert Cohen has been awarded the Elihu Thomson Resistance Welding Award by the American Welding Society (AWS). The honor, which recognizes individuals who have made outstanding contributions to the technology and application of resistance welding, will be awarded at AWS’ FABTECH […]
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, […]
Which is better for performing precision welding, a low friction pneumatic cylinder or a servo motor? High performance monitoring of the welding process makes the answer obvious.
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 qualityBy 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 heat […]
