Weld Monitor

With increased emphasis on the accountability and traceability of resistance welding processes comes the need for process monitoring and enhanced process control.

Weld Monitors provide precision real-time dynamic measurement of all welding variables and are invaluable tools for:

  • Process Development: Welding Evaluation and Research, DoE Studies, Process Optimization, Process Validation
  • Process Monitoring: Data Logging, Setting Process Limits, Electrode Maintenance, Troubleshooting, Set-up Verification, Statistical Process Control
  • Quality Control: Traceability, Process Certification and Analysis, Calibration Confirmation, Statistical Process Control


More specifically, Weld Monitors and Checkers measure voltage and/or current during the resistance welding process. Their basic functions are to provide data to be used in statistical determinations and to monitor the ongoing process and alert the user to unacceptable variations in a voltage or current-based parameter.
