The classification of welding roller stands is as follows:

Self-adjusting wheel stand: This wheel stand automatically adjusts the distance between wheels to accommodate workpieces of different diameters. No manual adjustment is required, making it suitable for handling workpieces of various sizes, especially those with significant diameter variations.

Adjustable Screw Wheel Stand: This wheel stand requires manual adjustment of the wheel position to accommodate different diameters of workpieces. It is more affordable but requires more manual intervention during operation. Suitable for applications where the size of workpieces changes infrequently.

Hydraulic Roller Stand: Adjusts the position of the rollers and supports workpieces through a hydraulic system. Offers greater control and more power, particularly suitable for heavy-duty and larger-sized workpieces.

Electric Walking Wheel Stand: This wheel stand allows for the movement of workpieces via an electric system, suitable for welding longer workpieces.

Team Rolling Stand: Allows for the welding of multiple workpieces together, suitable for mass production.
