How often should calibration be performed on welding equipment?

• A. Annually
• B. Per manufacturer's recommendations or contract; maintain calibration records
• C. Never needed
• D. Only when equipment fails

Answer: (B)

Regular calibration keeps welding equipment readings and control settings accurate, which is essential for consistent weld quality and safe operation. Over time, gauges, sensors, flow meters, and related controls can drift due to wear, temperature changes, or repeated use, and this drift can lead to out-of-t tolerance welds if not checked. The best practice is to calibrate according to what the equipment manufacturer specifies or what the contract requires, and to document the calibration in a records system. calibration records provide traceability, show that the equipment was verified to be within tolerance before use, capture who performed the check and when, and indicate when the next calibration is due. Relying on failures to trigger calibration or treating calibration as optional is not appropriate, since routine checks help prevent quality problems and nonconformances.
