Welding Machine CalibrationCalibrating and certifying your welders is an important function to ensure your welding machines are performing within the appropriate specifications.  Calibration is a process of going through the meters on your machine and adjusting them to factory specifications. After having your welder calibrated you can certify the calibration. By certifying your calibration you are supplying a paper trail showing that the calibrated meter can be traced back to the National Institute of Standards and Technology (NIST).  

Certified Calibration will guarantee your welding procedures are accurate across all of your machines.  Combined with a preventative maintenance program a calibration program is the best way to keep your machine running at optimum performance. 

Before creating a welding procedure your welding machine should be calibrated.  This allows the procedure to be written under a controlled environment. It also creates a benchmark for all of your welding machine to be held to. It is recommended that your machine be calibrated annually. Calibration procedures should be written into ISO specifications. 

The purpose of ISO standards is to establish that your customers purchase products that are designed, built, tested, and sold under controlled conditions. Welding machines out of calibration create an environment where welder error is possible. ISO audits are concerned with the documentation that businesses have, and whether they are following those set standards in their work procedures. When creating a calibration and preventive maintenance schedule it is important to write these procedures into the ISO standard. 

Calibrating all of your machines allows a welder to use the welding procedure and know what results to expect no matter what welding station is being used. Calibrated machines reduce set-up cost. Non-calibrated machines can produce welds that need to be repaired, even though the welder followed the welding procedure. Any automated welding process needs to be calibrated regularly to ensure weld quality over time. Fabrication costs can increase with un-calibrated welders.  If you have any questions or are looking for more information on calibration and certification please contact info@ceekay.com.

Today’s welding requires properly calibrated power supplies, controls and wire drives in order to achieve quality welds.  Correctly setting and controlling the welding procedure becomes critical when the industry is dealing with a reduced pool of talented weldors and they are being asked to operate high production mechanized and automatic welding systems.  Welding costs increase by 100% or more when re-work is required,” said Lon Yost, Global Application Engineer for Lincoln Electric.
