1. The roller frame for girth welding of large containers refers to the equipment used to support and assist girth welding of large containers. Its characteristics are: high stability, wide applicability, strong durability and simple operation;

2. In order to prevent axial movement, the following measures can be adopted:

3. Adjust the roller frame and replace or repair worn parts. This can make the roller frame run more smoothly and avoid the axial movement of the container during welding;

4. Accurately locate the weld of the container. If the weld is not accurately located in the center of the roller frame, the container may move axially. Therefore, the location of the weld should be as accurate as possible to ensure the smooth and correct welding process;

5. Use appropriate adjustment mechanism. The adjusting mechanism on the roller frame can adjust the welding position according to the position and angle of the welding wire. By adjusting the adjusting mechanism, the position of the weld can be ensured to be accurate, thus avoiding axial movement.
