Calibration

WTTI offers calibration services for welding equipment and welding electrode ovens (with or without temperature controls).

Our procedures meet the requirements of AWS D1.1-04, para. 5.11; AWS QC 4-89; Mil-Std-278E, para. 4.4.1, and similar specifications requiring verification of equipment accuracy. Calibration meters are each labeled with an identification number that attests to its accuracy and traceability to the National Institute of Standards and Technology.

Documentation: WTTI provides two forms of calibration documentation: 1) a data report detailing all pertinent information about the welding unit and/or rod oven to be kept on file, and 2) a calibration label to be attached to the welding unit and/or rod oven attesting to its meter calibration.

Calibration must be done annually and after any major maintenance has been performed. In some cases, however, in accordance with AWS D1.5, calibration is required every 3 months.  The duration between calibration depends on the code requirements.

Did you know?

The term "calibration" refers to the verification and validation of the equipment used for welding.

Calibration ensures that your welding machine is operating within the parameters of your welding procedure.  If an uncalibrated machine is used for welding and the fabricated piece fails in service, the company responsible for the weld and fro not calibrating their machines could be subject to investigation and potential monetary loss.

By utilizing WTTI's qualified professionals to calibrate your welding equipment, your company can save time and money.
