Welding · LPG cylinder production line

Both sides of the circumferential seam arc at the same time, balancing heat input so ovality change stays small and no re-rounding pass is needed.
The torch follows the joint in real time, so fit-up variation in incoming parts does not turn into weld deviation.
Each cylinder type and plate thickness has a stored program; a size change is a recipe call, not a manual setup.
