Our auger (screw conveyor) shafts are professionally manufactured with diverse welding options for spiral flights to match different working conditions.
### Welding Types for Spiral Flights & Shaft
We adopt multiple mature welding processes: continuous full welding, intermittent segment welding, and plug welding.
- Full welding: Strong bonding between flight and shaft, excellent resistance to heavy load and abrasion, suitable for high-density, coarse and abrasive materials.
- Spot welding: Reduce thermal deformation, save production cost, ideal for light, low-abrasion powder & pellet materials.
Spiral flights can be made from solid rolled flight or segmented plate flight, custom pitch and outer diameter available.
### Production Advantages
1. Precision machining: Shaft journals are finely turned to guarantee coaxiality, avoid vibration during high-speed operation.
2. Strict raw material control: Carbon steel, stainless steel, wear-resistant steel (Hardox optional) for selection.
3. Customization support: Custom length, shaft diameter, flight thickness, pitch, end connection structure according to your drawings.
4. Quality inspection: 100% weld visual inspection and straightness test before delivery.
### Product Performance
- High structural rigidity, anti-bending, stable rotation under continuous heavy-duty running.
- Good wear resistance; optional hard surfacing treatment for flights to extend service life when conveying abrasive materials.
- Smooth material conveying, low material blockage rate.
- Adapt to low and high temperature environments, anti-corrosion option for corrosive medium.
### Application Fields
Widely used in agriculture feed conveying, mining, metallurgy, cement, food processing, wastewater treatment, biomass energy, chemical powder transport, piling machinery and drilling auger equipment.
