Double-Gun Centrifugal Fan’s Casing 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.

Centrifugal Fan Housing Welding Range The automatic centrifugal fan housing welding machine is suitable for ordinary Carbon Steel and industrial Stainless Steel materials! Dimensions diagram： Minimum Radius of the Centrifugal Fan housing is 280mm,  Maximum Radius is 1700mm,  Width is 65-800mm, Thickness is 1.5-5mm, Weight is less than 500KG.

Altron‘s Centrifugal Fan Housing Welding solution adopts gas shielded welding technology and mechanical profiling welding (mechanical profiling requires that both sides of the centrifugal fan housing are flat and without reinforcement ribs). The equipment has a welding blind spot, and the mechanical profiling mechanism cannot enter, which will cause the last small section to be unable to be automatically welded.

Welding Steps For Centrifugal Fan Casing

Pre-operation debugging:

1. Input the required workpiece parameters, such as material thickness, minimum and maximum diameters, width and other information.
2. Adjust the parameters of the welding machine and wire feeding equipment.
3. Fix the workpiece to the rotating fixture on the spindle part! Two fixing methods:
① Pneumatic clamp  (for centrifugal fan housing with thicker wall thickness),
② Disc fixing  (for housing with thinner wall thickness or larger and heavier centrifugal fan).

Operation welding process:

1. After the centrifugal fan housing is fixed, press the start button, and the welding part automatically moves to the contour welding position according to the input workpiece parameters.
2. The equipment starts automatic welding according to the input data.
3. After welding is completed, remove the welded centrifugal fan housing and weld the next housing.
