Product Description

1. Equipment Overview
The liquefied petroleum gas cylinder base welding equipment is an innovative marvel engineered for the seamless automatic welding of LPG cylinder bases and bodies. This state-of-the-art equipment leverages cutting-edge welding technology and a sophisticated intelligent control system to deliver unwavering welding quality. It adheres to stringent global standards like GB/T 5842-2023 "Liquefied Petroleum Gas Cylinders" and ISO 22991, making it perfect for extensive industrial-scale production.

2. Equipment Structure and Composition
This advanced device is primarily comprised of the following pivotal modules:
• Frame and Transmission System
The equipment's design features a robust high-strength steel frame that ensures steady performance and exceptional anti-vibration capabilities.
It incorporates a high-precision rotating mechanism powered by a servo motor, facilitating uniform cylinder rotation and guaranteeing consistent welding results.
• Clamping Positioning System
Utilizing pneumatic/hydraulic fixtures, it adapts effortlessly to cylinders of varying specifications (15kg, 50kg, etc.), ensuring the base aligns with precision to the cylinder body (error ≤±0.15mm).
These fixtures are configurable as per cylinder specifications, allowing universal welding of various gas cylinder bases.
• Welding System
Select from MIG (Metal Inert Gas Welding), MAG (Active Gas Welding), or TIG (Tungsten Inert Gas Welding) for welding. The system accommodates welding of carbon steel (Q235B) or stainless steel (304) shields.
The welding power supply features a digital inverter welding machine providing stable output, with precise control over current (100-350A), voltage (18-32V), and wire feed speed (2-12m/min).
o Welding Torch Mechanism: The air-cooled welding torch offers multi-angle adjustments to guarantee comprehensive weld seam coverage.
• Automated Control System
o PLC + Touch Screen: This system facilitates welding parameter storage, program invocation, fault diagnosis, and supports multi-formula switching.
The Human-Machine Interface (HMI) features a visual operation panel displaying real-time data on welding speed, temperature, and gas flow rate.
• Safety and Environmental Protection Systems
o Gas Protection: Equipped with a high-precision flowmeter, it maintains a constant Ar/CO2 mixed gas ratio (typically 80% Ar + 20% CO2), preventing weld oxidation and ensuring optimal protection.
Safety features include protective covers, emergency stop buttons, and leakage protection to mitigate operational risks.

3. Workflow
• Feeding and Positioning: Gas cylinders and bases are manually or mechanically placed in the fixture. The system automatically clamps and precisely corrects their position.
• Welding Execution: The PLC initiates the welding torch while the cylinder rotates consistently, completing the circumferential seam welding between the base and cylinder body (single or multiple welds).
• Cooling Inspection: Post-welding, automatic air-blowing cooling occurs alongside a preliminary appearance check (e.g., weld height and continuity).
• Material Cutting and Sorting: Qualified products advance to the next stage, whereas those unqualified are marked for rework.

4. Technical Parameters
Project Parameters
This equipment is adept for standard LPG cylinders, accommodating specifications from 3KG to 50KG and beyond.
The welding speed is impressively adjustable, ranging from 200 to 600mm per minute, providing flexibility to suit various production needs.
Expertly handles welding thicknesses from 2mm to 6mm, adeptly accommodating both the base and the bottle body for a seamless finish.
Power is supplied through a robust 380V/50Hz system, utilizing a three-phase five-wire configuration to ensure reliable performance.
Exhibiting efficiency, the equipment power is rated at 0.55KW, adaptable to the specific demands of the welding process.
Production efficiency shines with the capability to produce 50 to 100 pieces per hour, depending on the intricacies of the weld requirements.

5. Quality Assurance
• Conducts weld seam inspections using advanced X-ray flaw detection (RT) or ultrasonic testing (UT), meticulously ensuring absence of defects like pores, slag inclusions, or incomplete fusion.
• Undertakes strength tests with precision, where tensile tests ensure the weld seam exhibits a tensile strength ≥ 90% of the base material, affirming durability and reliability.
• Executes air tightness tests through helium mass spectrometry leak detection or hydrostatic testing, ensuring a leakage rate of ≤0.1Pa·m³/s, signifying superior integrity.

6. Application Scenarios
• Ideal for LPG cylinder manufacturing plants, this machine excels at welding the base of new cylinders, ensuring high-quality production.
• Perfect for cylinder inspection stations, facilitating base replacement or repair welding with precision and ease.
• Versatile for special container production, adept at circular welding for other metal containers requiring meticulous craftsmanship.

7. Optional configuration
• Upgrade to a dynamic robot welding unit, featuring six-axis robot collaboration for simultaneous welding across multiple stations, enhancing efficiency.
• Employ a sophisticated laser weld seam tracking system, offering real-time corrections to the welding path, thereby improving the accuracy of complex structures.
• Maximize efficiency with a double-station design, allowing alternating loading and unloading, achieving a remarkable 40% increase in productivity.
