Adaptive IQR

Harms & Wende resistance welding controls, equipped with Adaptive IQR, offer powerful process control through monitoring and testing systems that identify variances and adjust the control accordingly without additional programming.  Through development of the IQR adaptive control system, Harms+Wende has set the standard for simplifying high quality resistance welding. The Harms & Wende product line of resistance welding machine controls allows a variety of materials, as well as high and ultra-high-strength steel grades, to be joined quickly and economically.

Due to the resistance of the current passing through different metals and well as machine and tip wear over time, inconsistencies occur, and are difficult to pinpoint without extensive troubleshooting. The H&W next generation of resistance spot welding control, equipped with the intelligent IQR algorithm, provides rapid correction of anomalies in the resistance welding process automatically by sensing variations of resistance during the weld and makes corrections by changing current (and optionally weld time). The control is equipped with the ability to sense these slight changes and adjust the weld as it progresses, without the need of additional programming by an engineer or operator.

Please contact T. J. Snow to learn if the IQR Adaptive Resistance Welding control is a good application for your resistance welding process. Harms & Wende offers one of the only adaptive controls for Aluminum resistance welding.

How do you say the name?

Here is your short German lesson: Germans say the letter “W” as an english “V” sound. So Harms & Wende is pronounced, “Harms & Vende”!
