Automatic LPG Gas Cylinder Welding Line: Comprehensive Guide

MIDDLE EASTERN, Afghanistan - Sept. 4, 2024 - PRLog -- Working Principle of the Automatic LPG Gas Cylinder Welding Line

The Automatic LPG Gas Cylinder Welding Line consists of multiple machines that work together to automate the entire welding process for gas cylinders. Each machine is specifically designed to handle a unique part of the welding process, ensuring precise and consistent results. Here's a breakdown of the main machines involved in this line:

1. Automatic Socket Welding Machine
This machine is responsible for welding the upper cap socket to the cylinder body. Using a four-column hydraulic presser structure, the welding process begins by manually placing the socket into the upper cap center hole. The hydraulic system clamps the workpiece, and the automatic arc welding begins. At the same time, an inner polishing dish polishes the welded edges. The machine ensures simultaneous welding and polishing, providing a clean finish in one step.

Key Specifications:

• Equipped with Panasonic YD-350GL4 welder
• Motor power: 0.75KW (main shaft), 1.5KW (polishing motor)
• Water-cooled welding torch for continuous operation

2. Automatic Handle Welding Machine
This machine handles the welding of handles onto the upper cap of the cylinder. Three welding torches are used simultaneously, ensuring that the handle is securely welded in one pass. It operates using a PLC-controlled hydraulic presser system, with the mechanical arm assisting in loading and unloading the workpieces.

Key Specifications:

• Equipped with 3 sets of Panasonic YD-350GL4 welders
• Motor power: 0.4KW
• Grating security protection for safe operation

3. Automatic Bottom Base Welding Machine
The bottom base of the cylinder is welded to the lower cap using this machine. Similar to the handle welding machine, it uses multiple torches to weld the bottom base in one cycle, with hydraulic pressing ensuring a firm attachment between the components.

Key Specifications:

• Uses 3 welding torches, with up to 6 welders operating in two cycles
• Motor power: 0.4KW
• Fully automated loading and unloading

4. Automatic Circumferential Seam Welding Machine
One of the most critical stages in cylinder manufacturing is the circumferential seam welding. This machine is equipped with a welder vision tracking system that ensures precision during the welding of the cylinder's upper and lower caps. The system automatically tracks and adjusts the welding torch to follow the seam, ensuring a smooth and consistent weld.

Key Specifications:

• Panasonic YD-500GS high-speed welder
• Water-cooled welding torch
• Vision tracking system for precise welding
