Laser vs. Flame Cutting — How to Choose
Laser cutting is not always the better option. The right choice depends on plate thickness, required tolerance, edge condition, and your application.
| Factor | Laser Cutting | Flame Cutting |
|---|---|---|
| Thickness range | 0.5–55mm | 30–200mm |
| Dimensional tolerance | ±0.1 ~ ±0.3 mm | ±0.5–1mm |
| Cut surface quality | Surface quality is controlled according to material, thickness and project requirements. | |
| Edge finishing needed | Minimal — deburring usually sufficient | Slag removal, grinding recommended |
| Complex shapes | Excellent | Better for simple profiles |
| Thermal distortion risk | Lower | Higher on long/narrow parts |
| Maximum panel size | 3500×26000mm | 5500×30000mm |
Choose laser cutting when:
- Plate thickness is within YUNCUT's published laser range (0.5–55mm) and the drawing is suitable for laser processing
- Critical dimensions are better matched to the published laser tolerance reference (±0.1 ~ ±0.3 mm), subject to geometry review
- Parts have complex shapes, tight holes, or intricate profiles
- Clean edge condition matters for welding, coating, or assembly
Choose flame cutting when:
- Plate thickness, material, and geometry are better matched to the published flame-cutting range (30–200mm)
- The project can accept the published flame-cutting tolerance reference (±0.5–1mm), subject to part geometry and measurement method
- Large format panels are required (up to 5500×30000mm)
- High volume heavy structural plate where cost efficiency matters
The 30–55mm overlap zone
Both methods may be viable in the published overlap range. Final selection depends on material, geometry, tolerance, edge condition, downstream operations, and commercial requirements. Share the drawing or finished-part requirement for review.
Summary
Cutting method selection is not about which is "better" — it is about matching the method to your thickness, tolerance, and application. When in doubt, share your requirements and we will advise.
