Automatic Girth Welding Machine For LPG Gas Cylinder

This automatic girth welding machine is designed specifically for automated welding of longitudinal and circumferential seams on LPG gas cylinders. It utilizes PLC intelligent control, enabling simultaneous welding with two welding guns. It also features a roller support and an independent operating table. This automatic girth welding machine supports mainstream power supply brands such as Aotai, Panasonic, Lincoln, and Fronius, meeting the technical requirements of diverse customers. It is particularly suitable for the manufacture of high-strength pressure vessels and mass production of storage tanks.

Application:

This automatic girth welding machine is widely used for automated welding of circumferential and longitudinal seams on cylindrical workpieces such as liquefied petroleum gas (LPG) tanks, pressure vessels, air storage tanks, hot water boilers, and chemical reactors.

Advantage

Advantages of Automatic Girth Welding Machine:

1.Equipment Components: The machine integrates a welding gantry, workpiece positioner, welding power supply system, and welding gun control system.

2.Highly Automated Control: The machine utilizes a PLC and variable frequency drive system for precise speed regulation and constant torque output, ensuring smooth low-speed starts and stops.

3.Stable and Reliable Structure: The welding gantry is a custom-made steel structure with high strength and rigidity, ensuring long-term stable operation.

4.High Positioning Accuracy: The workpiece positioner features a self-locking function, ensuring the workpiece remains securely positioned at any angle.

5.Excellent welding consistency: The welding gun control system can be equipped with optional laser tracking to achieve automatic seam alignment and weld bead correction to ensure weld consistency and aesthetics.
