Product Description

1. Equipment Overview
Introducing our state-of-the-art, specialized Foot-Ring Welding Machine for LPG Cylinders! Engineered with precision, this automatic welding marvel caters solely to the needs of LPG cylinder bases and bodies. Utilizing cutting-edge welding innovations and a sophisticated intelligent control system, it guarantees exceptional and unwavering welding quality. This equipment is crafted to align with the stringent standards of GB/T 5842-2023 'Liquefied Petroleum Gas Cylinders' and ISO 22991, making it an ideal choice for extensive, large-scale industrial operations.

2. Equipment Structure and Composition
This ingenious device is constructed with the following essential modules:
• Frame and Transmission System
Built on a robust high-strength steel frame, this equipment ensures unparalleled stability and exceptional resistance to vibration, delivering a smooth operational experience.
Outfitted with a high-precision rotating mechanism driven by a servo motor, the system allows seamless, uniform speed rotation of the gas cylinder, ensuring immaculate welding uniformity.
• Clamping Positioning System
Our adaptable pneumatic/hydraulic fixtures accommodate gas cylinders of varying sizes (15kg, 50kg, etc.), guaranteeing flawless base-to-cylinder alignment with an impressive error margin of ≤±0.15mm.
Fixtures are versatile and customizable for different gas cylinder specifications. By simply adjusting the fixtures, the machine can universally weld bases for a wide range of cylinder sizes.
• Superior Welding System
Choose from an array of welding methods: MIG (Metal Inert Gas Welding), MAG (Active Gas Welding), or TIG (Tungsten Inert Gas Welding), perfectly suited for welding carbon steel (Q235B) or stainless steel (304) shields.
Incorporating a digital inverter welding machine, this system boasts a stable output, precisely regulating current (100-350A), voltage (18-32V), and wire feeding speed (2-12m/min) for superior results.
o Welding Torch Mechanism: Featuring an air-cooled welding torch, it offers multi-angle adjustments to ensure comprehensive weld seam coverage.
• Automated Control System
o PLC + Touch Screen Interface: Store welding parameters, effortlessly invoke programs, diagnose faults, and seamlessly switch between multiple formula sets with this intuitive system.
Boasting a Human-Machine Interface (HMI), the visual operation panel provides real-time data displays, including welding speed, temperature, and gas flow rates, for an interactive user experience.
• Safety and Environmental Protection Systems
o Gas Protection: Equipped with a high-precision flowmeter, it guarantees a consistent Ar/CO2 mixed gas ratio (standard 80% Ar + 20% CO2), effectively preventing oxidation of the weld.
Safety measures are paramount, with protective covers, emergency stop buttons, and leakage protection to mitigate operational risks.

3. Workflow
• Feeding and Positioning: Manually or mechanically position the gas cylinder and base in the fixture. The system will automatically clamp and precisely correct their positions.
• Welding Execution: Governed by the PLC, the welding torch initiates, and the cylinder rotates at a steady pace, flawlessly completing the circumferential seam welding between the base and cylinder body, accommodating single or multiple welds.
• Cooling and Inspection: Post-welding, enjoy automatic air-blowing cooling. Conduct a preliminary inspection of the weld's appearance, checking for ideal height and continuity.
• Material Cutting and Sorting: Seamlessly transfer qualified products to the subsequent process, while marking and redirecting unqualified products for rework.
