How To Weld A Centrifugal Fan Impeller

The welding of impellers is an indispensable part of centrifugal fan manufacturing. With the development of society, traditional impeller welding methods can no longer meet the requirements of high output, high quality, and other demands. The development of robotic automatic Industrial fan welding will become a new direction in the future.

Common Assembly Methods Of Industrial Fan Impellers

Here are three welding methods for Impellers! Applicable to the production processes and production models of different industrial fan manufacturer factories

1. Laser Marking and Manual Spot Welding

First, index the blades to determine their positions on the impeller.
Then, manually input parameters (including start and end points) and generate a motion trajectory.

2. Traditional Automatic Welding Equipment

It requires ‘teaching programming’ and cannot achieve real-time tracking of the welding position or correct the welding trajectory—thus failing to realize a truly automatic welding process. Additionally, the assembly of the centrifugal fan impeller’s (front disk) shield and blades cannot be completely consistent. During welding, heat is generated, which causes impeller deformation. Applying the teaching-programming welding method to impeller welding will lead to reduced welding quality.

3. Principle of Laser Vision-Guided Automatic Welding Robot for Centrifugal Fan Impellers

Before welding, the robot uses a camera and laser to scan the welding position. The welding trajectory is automatically generated by software, eliminating the need for teaching programming.

1. ABB welding robot system
2. Dual-axis sensor
3. Laser vision guidance system
4. Welding system
5. Welding torch cleaning system
6. Safety protection system

Choose Altron And Start Your Automatic Welding Industrial Fan Project

1. Determine the welding scope and welding process of fan impeller accessories：

– Impeller diameter, height, and weight
– Welding process requirements (full welding or intermittent welding)

Google meetings can be used to quickly discuss welding details and techniques whit Altron‘s engineer.

2. Ask The Manufacturer To Analyze Relevant Information And Conduct Welding Verification

– STP format drawings (for the largest or smallest impeller by size)
– 3D models (Altron can conduct welding simulation based on these)
It enables automatic welding of centrifugal fan impellers, fan casings, and other fan components. Specific benefits include

3. Select different welding machines according to the type of impeller and welding process requirements.

According to the technical requirements of industrial fan manufacturers for Industrial fan welding, they should choose welding brands such as Fronius, Lincoln, Miller, ESAB, Kemppi, Panasonic, Otech, etc.;

It is also necessary to select different welding processes based on different materials of the impeller. For example：
