How to judge whether the socket fusion welding machine needs calibration?

1. Unstable welding quality
If too many defects such as pores, cracks, and unfused joints are found, and pipe and operation problems are excluded, it may mean that the parameters of the welding machine are inaccurate and need to be calibrated.
2. Welding parameter deviation
Compare the actual welding parameters (such as temperature, pressure, time, etc.) with the set parameters. If there is a large deviation, it indicates that the welding machine may have lost the ability to accurately control the parameters and needs to be calibrated.
3. Equipment usage time
According to the equipment manufacturer's recommendations, after a certain period of use, even if there are no obvious signs of failure, regular calibration should be performed to ensure that its performance remains within the specified range.
4. Changes in environmental conditions
If the welding machine works in a harsh environment (such as high temperature, high humidity, strong electromagnetic interference, etc.) for a long time, it may affect its accuracy and calibration needs to be considered.
5. Comparison with standard test pieces
Use standard pipes and fittings for welding, and compare the welding results with known standard test pieces. If the difference is large, the welding machine may need to be calibrated.
6. After repairing or replacing parts
When the socket fusion welding machine has repaired or replaced important parts, such as heating plates, controllers, sensors, etc., calibration should be performed to ensure the matching and accuracy of the new parts with the overall system.
7. Production process changes
If the material or specifications of the welded pipes or fittings have changed, and the welding effect is not ideal, the welding machine may need to be calibrated to adapt to the new process requirements.
8. Comparison with other socket fusion welding machines of the same model and working properly, if the welding effect of your own equipment is significantly different, calibration may be required.
