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.
Standard machine data below. Non-standard sizes can be tooled to your cylinder drawings.

The more specific your information, the more accurate the quote. Ideally include: cylinder size (1 / 5 / 12.5 / 15 / 25 / 50 kg), sheet thickness, target daily output, existing process and available floor area.
