Welding Equipment Calibration
Welding equipment calibration is a regular check and adjustment of power sources, wire feeders, and measuring devices to ensure process-relevant tolerances. This ensures that welding parameters like voltage and current are correct.
Physicochemical mechanism of action
Calibration of welding equipment involves testing and adjusting electrical parameters such as voltage and current. This is achieved by comparing against standard values or reference measurements to ensure that the equipment correctly delivers its specified performance parameters.
Metallurgical relevance & risks in welding
Incorrect calibration can lead to inaccurate welding parameters, which in turn can result in poor weld quality, porosity, or insufficient toughness. This increases the risk of cracks and reduces the service life of components.
Workshop practice & instructions
Calibration should be performed at least monthly, depending on the equipment model and application. The exact steps vary by equipment, but it is important that all measuring instruments are regularly checked and corrected against their reference values. If necessary, follow the manufacturer's instructions.
