The sheet metal hood collected fumes around a robotic welding station while managing local heat and spatter.
The customer’s challenge
Poor collection allowed fumes to escape, while heat near the torch distorted the hood and spatter created a fire risk.
Material and fabrication route
1.5 mm galvanized steel; heat-resistant coating.
Process route: Laser cutting → bending → welding → heat-resistant painting → flange assembly → airflow testing.
Manufacturing changes
The hood opening and extraction flow were revised. Insulation protected hot zones, a spark screen was added, and removable sections enabled cleaning.
Engineering analysis
Fume capture depended on the relationship between the hood opening and extraction flow, while the nearby welding process also imposed heat and spatter exposure. Geometry and airflow changes addressed collection; insulation and the spark screen addressed the hot zone. The collection percentage and temperature result describe different checks on the installed arrangement. Serviceable sections mattered because deposits still needed to be removed during use.
Inspection and project results
The project achieved ≥95% fume collection without the observed hood distortion in the tested arrangement.
| Project measurement or production detail | Recorded value |
|---|---|
| Fume collection | ≥95% |
| Temperature test | ≥200°C |
| Airflow | ≥2,000 m³/h |
| Hood opening | 400 × 300 mm |
These figures describe the project configuration and production scope above. Dimensional, material and production details are identified separately from performance tests. For a new order, the inspection method and acceptance criteria should be agreed against the released drawings.
Planning a similar OEM component
A useful RFQ for this application should make the following interfaces and acceptance requirements clear:
- Torch and workstation envelope.
- Extraction flow and connection.
- Heat and spatter exposure.
- Collection-test and cleaning-access requirements.
Include the current drawing revision, mating-component information, quantities and required delivery sequence. Identifying unresolved requirements at quotation stage helps distinguish fabrication work from the equipment-level checks that the project needs.
