Development of a Weld Quality Monitor
Ralf Weber, Frank W. Kearney, S. Joshi · 1976
Abstract : A weld monitoring system has been developed based on conditioning the primary signals from the welding machine and comparing them with preset limits. A light is activated when a welding parameter such as voltage, current, or heat input is outside the control limits. The circuitry has been tested with simulated primary signals. The voltage channel has also been tested using primary signals from an automatic gas metal-arc welding machine.
