First of all, used equipment often experienced a long time of use, equipment wear and aging is inevitable. When key components such as electrodes, welding guns or control systems age, it is difficult to ensure the stability of current and pressure during welding, which can easily lead to problems in welding uniformity.

Secondly, due to the uneven maintenance level of the welding pipe machine from different manufacturers, the historical status of the second-hand equipment is also different, and some may be improperly maintained or not calibrated regularly before, further aggravating the phenomenon of uneven welding.
Finally, there is sometimes a big gap between the technical specifications of used tube mills and modern technology, and the technical performance may have lagged behind and cannot meet the current higher welding accuracy requirements.
Therefore, for those considering purchasing used tube mills, it is necessary to carefully assess the condition of the equipment and carry out the necessary maintenance and calibration to reduce the risk of uneven welding.
