Calibration control of an electric welding station is an essential step aimed at precisely verifying the machine's parameters to ensure proper functioning and the delivery of expected performance.


Manufacturing standards or sector-specific specifications set requirements for the control of welding equipment to guarantee quality welds.


Here are the general steps of calibration:

1. Recording and verification of welding parameters such as voltage, current, wire speed (in the case of MIG/MAG welding), and polarity.

2. Verification of no-load voltage.

3. Verification of the recorded data and comparison with the tolerance range set by the standard.


Two accuracy classes are distinguished, meaning two tolerance thresholds (expressed in %):

  • Standard class: +/- 2.5%
  • "Precision" class: +/- 1%


Calibration Service HD SOUDAGE: How does it work?


For the past 12 years, we have been providing calibration services to industries in the metal construction, shipbuilding/repair, nuclear industry, and chemical/petrochemical sectors.


Our teams perform the service either in the workshop or on-site (with a minimum of 6 units). We use second-generation calibration equipment, and our instruments are verified annually by a COFRAC-approved third-party establishment.


Each service is subject to a prior intervention quote. Calibration certificates are sent by email within 48 hours after the operation's completion.
