The appropriate temperature for welding straight seam steel pipes depends on the material type and wall thickness. For low-carbon steel straight seam pipes, the welding temperature should typically range from 1250°C to 1460°C. This range ensures proper fusion while maintaining the integrity of the weld.
Key Considerations:
- Material Properties:
Low-carbon steel has a relatively low melting point, making the specified temperature range suitable for achieving a strong weld without compromising the material structure.
- Wall Thickness:
The 1250°C to 1460°C range is specifically appropriate for steel pipe wall thicknesses of 3 to 5 mm. Adjustments might be needed for thicker or thinner walls.
- Heat Input Balance:
Insufficient Heat: Edges may not reach the required welding temperature, leading to incomplete fusion or weak welds.
Excessive Heat: Overheating can cause structural damage, weld degradation, or formation of molten droplets.
Maintaining a consistent and controlled welding temperature within this range is critical for ensuring the durability and performance of straight seam steel pipes.
