Weld monitors measure one or more of the electrical and/or mechanical parameters that dynamically change during the welding process including weld current, voltage drop across the electrodes, work piece expansion and deformation, electrode force, electrode displacement (movement) and more.Resistance welding process monitors (weld checkers) measure and monitor the different variables that are simultaneously occurring during the resistance welding process. These tools help identify areas of improvement and overall process development.
