Automatic Laser Coiling Welding Machine

Product Overview

This machine seamlessly integrates automatic coil forming with laser welding technology, specifically designed for coiling metal sheets and welding longitudinal seams. Through the coordinated operation of a high-precision coiling mechanism and a fiber laser welding system, it achieves full automation from loading, coiling, welding to unloading. Widely used in industries such as can manufacturing, fire-fighting equipment, transformer casings, pressure vessels, and piping, it meets the demand for efficient, high-quality circular workpiece welding.

Features

– **Integrated Coiling & Welding**: Combines forming and welding in one process, eliminating secondary handling, reducing cycle time, and minimizing workpiece deformation.

– **Fully Automatic Operation**: Equipped with automatic loading/unloading systems and PLC control for unattended or minimal-operator production, ideal for mass manufacturing.

– **High-Precision Positioning**: Servo-driven coiling rollers and laser seam tracking ensure uniform joint gaps and precise weld placement.

– **Wide Adaptability**: Adjustable coiling diameter and material thickness accommodate various metals such as stainless steel, carbon steel, aluminum alloy, and galvanized steel.

– **Stable & Reliable**: Robust frame and precision guides guarantee long-term stability; the laser head automatically adjusts to different workpiece sizes.

Advantages

– **Superior Weld Quality**: Laser energy concentration results in narrow heat-affected zones, clean and strong welds, requiring little to no post-weld grinding.

– **High Production Efficiency**: Simultaneous coiling and welding drastically shortens processing time per part, boosting output.

– **Labor Cost Reduction**: Automation minimizes manual intervention, reduces labor intensity, and eliminates human errors.

– **Flexible Manufacturing**: Quick changeover features adapt to various diameters and lengths, supporting multi-specification, small-batch production.

– **Eco-Friendly**: Low energy consumption, no consumables, and no harmful fumes during welding align with green manufacturing trends.

Applications

– **Can Manufacturing**: Longitudinal seam welding of beverage cans, food cans, chemical drums, and other cylindrical containers.

– **Fire-Fighting Equipment**: Coiling and welding of fire extinguisher cylinders and gas bottles.

– **Electrical Equipment**: Production of transformer casings and reactor enclosures.

– **Pressure Vessels**: Welding of small air tanks and liquid storage tanks.

– **Automotive Industry**: Manufacturing of mufflers, exhaust pipes, and filter housings.

– **Home Appliances**: Welding of water heater inner tanks, washing machine drums, etc.

– **General Machinery**: Circular components such as fan housings, pipe joints, and lamp casings.
