For resistance spot welding, resistance projection welding, and resistance seam welding, the RMS current needed to weld a specific material of a specific thickness will be similar for MFDC as for AC. If all things are considered equal, where the only variable is the weld transformer type, the same KVA MFDC or AC transformer is […]
Often resistance welding operators report that their setup is exactly the same except that now the welds are different. They don’t realize that a seemingly irrelevant adjustment to the geometry of the welding setup can change the spring constant of the linkages applying electrode force to the part. While a change in the spring constant […]

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 […]
WeldComputer Corporation today announced that Clifford Machines and Technology (Pty) Ltd., of South Africa, is the latest OEM partner to join its global team. The partnership extends WeldComputer’s presence in the region, and allows Clifford to supply a broad range of high-performance, advanced welding control and monitoring solutions for their line of mesh and grating […]
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, […]
Founded in 1987 to offer better, less wasteful ways to manage the welding process, WeldComputer is entering its fourth decade with the introduction of a new, intuitive touch-control panel; and the awarding of a new U.S. Patent to founder/CEO Bob Cohen. The patent covers a new process that provides a practical method for instrumenting new […]
