The cutting of S355K2G1W weathering steel plate is very important, mainly because the application of S355K2G1W weathering steel plate can be guaranteed after the cutting is completed, which can meet the needs of subsequent production.
In fact, the cutting work of S355K2G1W weathering steel plate is very important. Before cutting, it is necessary to pay attention to the corresponding adjustment. The distance between the S355K2G1W weathering steel plate and the guide rail should be adjusted. If the distance difference is large, it will directly affect the cutting quality. Especially need to pay attention to the corresponding thickness problem. After finding a suitable position, cut again to ensure the cutting angle, etc., which can bring good results.
Processing & Cutting Guidelines for S355K2G1W Weathering Steel Plate
1. Cutting Methods\n• Plasma/Laser Cutting: Preferred for precision; may leave a heat-affected zone (HAZ) – grind edges if needed.
• Oxy-Fuel Cutting: Suitable for thick plates (>20mm); preheat to 150–200°C to avoid cracking.
• Shearing/Mechanical Cutting: Use hardened blades for clean edges; deburr to prevent stress concentrations.
2. Drilling & Machining\n• Tool Material: Carbide or high-speed steel (HSS) bits.
• Coolant: Required to prevent work hardening; maintain speeds ≤ 120 m/min.
• Chip Control: Clear chips frequently to avoid surface contamination.
3. Welding Precautions
• Preheat: 100–150°C for thickness >15mm.
• Filler Metal: Use matching weathering electrodes (e.g., EN ISO 14341-A G 46 4 M21 4Si1).
• Post-Weld Cleaning: Remove slag/spatter to maintain corrosion resistance.
4. Bending & Forming
• Minimum Bend Radius: 2× plate thickness to avoid cracking.
• Cold Forming: Anneal if >10% deformation is required.
5. Surface Protection\n• Post-Cutting: Remove slag/oxides with grinding or pickling.
• Storage: Keep dry to avoid uneven patina formation before installation.
