Calibration of energy storage welder

Why is welding equipment calibration important?

There are many reasons that makes welding equipment calibration important: Precision and quality: A calibrated welding machine ensures accurate control over factors including wire feed speed, voltage, and current. This accuracy directly translates into consistent, high-quality welds to lowers the errors and rework.

Where can I find welding equipment calibration information?

This information is found in ISO/IEC 17025. The American Welding Society (AWS) has issued its own operational standards that apply to welding equipment used in construction and manufacturing in the United States. An Internet search will yield the numbers and titles of many documents that pertain to welding equipment calibration.

Should I calibrate my welding equipment before starting a new welding process?

Before starting any new welding processes, it is recommended to calibrate your welding equipment. This ensures that the welding processes carried out on your welding equipment are precise and that the procedures written are carried out in a controlled environment.

What is inspected when calibrating welding machines?

Welding machines are connected to a calibration station to inspect the actual voltage, amperage, and wire feed speed. It’s also possible to establish the welding current source's gas flow rate. Calibration and (or) validation each have two tolerances, these grades are standard and precision.

What is a standard for testing and calibration of welding equipment?

There is also an international standard that defines requirements for laboratories that perform testing and calibration. This information is found in ISO/IEC 17025. The American Welding Society (AWS) has issued its own operational standards that apply to welding equipment used in construction and manufacturing in the United States.

How often should a welding machine be calibrated?

4.3 Calibration records/log shall be maintained for all the welding machine calibration status and expiry date. 4.4 Frequency of calibration shall be every six (6) months of operation. 4.5 Welding Machines with expired CALIBRATION shall be tagged with “DO NOT USE” tag to prevent from utilization by the end user.
