The Importance of Welder Calibrations
What is a welder calibration?
Over time, welding machine meter readouts change and need to be readjusted.
A qualified welder technician can adjust the readouts on your machines meters . The technician will perform a detailed systems check by measuring the voltage, amperage and wire feed rates. They will then analyze your machines tolerances and adjust accordingly.
Ok sounds simple, but why?
If your machines meters are not properly showing the output of the machine you could start to experience issues that could diminish the strength of your weld and the quality of your work. For example if your voltage is too high, it can cause poor arc control and an unstable weld pool that leads to irregular penetration of the base metal. However, if the voltage is too low it can result in poor arc starts, excessive spatter and a bulged bead.
Do I have to calibrate my machine?
If you want to ensure that your welds are at their optimum strength and quality, then yes. The Canadian Welding Bureau recommends annual welding calibrations as part of an ongoing equipment maintenance program.
Calibrations can either be done in shop or conveniently on site, ensuring that you can return to work as quickly as possible.
What is certification?
Once your machine has been calibrated you can then have it certified. Certification proves that your machine has been calibrated properly and can be traced back to the National Research Council of Canada or the National Institute of Standards and Technology.
Having a stable and accurate welding process will save you time and money, as well as give you peace of mind that you’re producing a quality product.
