[0001] The invention relates to the technical field of roller processing and circumferential welding, and in particular to a cylindrical internal annular seam welding device. Background Art

[0002] When processing the cylinder, the inner and outer seams of the through plate need to be welded separately. Originally, when we processed the cylinder, we controlled the welding on the inside, used rollers to support the cylinder, and could adjust the angle of the cylinder. When the cylinder was adjusted to a suitable processing position, we rotated the cylinder for welding.

The rotation effect of the cylinder is not stable enough, and it is inconvenient to adjust according to cylinders of different sizes; 2. The method of adjusting the welding position by dual-axis feeding only infers the movement amplitude by calculating the driving time of the motor, which is inconvenient to directly measure and locate the welding point during the movement; 3. Lack of multi-axis adjustment of welding position function, large welding dead angle. Summary of the invention
