Dual-Gun Centrifugal Fan Casing Laser Welding Machine

Altron’s dual-gun centrifugal fan casing welding machine realizes a control method without programming. The machine interface inputs the maximum and minimum radius, length and width of the straight edge of the centrifugal fan casing to start the welding process, and is equipped with a profiling function. The mechanical contour ensures stability and reliability, and can correct the weld deviation in real time to achieve the best welding effect.

Advantages of Dual-Gun Centrifugal Fan Casing Welding Machine

1. Automatic welding without programming, enabling automatic welding of volute workpieces without manual intervention.
2. Manual switching function available for manual control adjustments when required.
3. System controls crucial parameters like welding speed, with fault alarms and prompts for manual intervention in case of equipment failure.
4. Simultaneous welding on both upper and lower sides of the workpiece, eliminating the need to flip the workpiece.
5. Fan casing should be wrapped for convenient copying and positioning, with a minimum hemming size specified.
6. At least one side of the fan casing must be flat, featuring a round hole in the center for positioning and clamping.
7. Suitable for circular flange workpieces and similar components within the welding technical requirements.
8. Volute thickness should be a minimum of 1.5mm.
9. Workpiece materials: carbon steel, stainless steel.
10. Equipment supports a minimum welding diameter of 300mm, maximum welding diameter of 3000mm, and a distance of 64-500mm between upper and lower welds.

Structure Of Dual-Gun Centrifugal Fan Casing Welding Machine

1. Base Platform: Provides installation and positioning of each device component, ensuring stability and preventing excessive shaking during welding.
2. Mechanical Profiling Double-Gun Manipulator: Profiles the weld bead of the workpiece, accommodating deformations within a 50x50mm vertical plane centered on the welding point. Simultaneously welds upper and lower welds without the need for flipping or secondary positioning, significantly improving efficiency for large workpieces.
3. Rotating Bottom Bracket: Offers a flat surface for the workpiece to rest on and allows 360-degree rotation. Equipped with an outrigger top block, facilitating alignment of the workpiece’s bottom round hole.
4. Electric Control System: Includes a main control PLC, a user-friendly human-machine control interface, peripheral servo system, various sensors, and intelligent elements for efficient operation.

Dual-Gun Centrifugal Fan Casing Welding Machine consists of a 3-axis welding manipulator, a rotary table, a base, a welding tracking system, a control system, and a MAG welding power lamp. The welding track is set by the system to match the workpiece size, the welding gun automatically guides the workpiece to perform contact elastic profiling tracking, and the welding height is automatically adjusted by the welding voltage.
