Welder verification

The process of calibrating welding systems involves them being connected to a calibration station to have their voltage, amperage, and wire feed speed measured. The calibration software analyzes the values recorded for your welding systems and compares them against the standard specifications in order to identify the discrepancy between the two. This result must fall within the permissible tolerances as set out by the European (EN) 50504 standard, “Validation of arc welding equipment.” If the results of the calibration process are not acceptable, the necessary measures will need to be taken. If a company does not take these required steps, they should not continue to use the welding machine for production—not least based on considerations surrounding quality assurance and product liability.
