Why Our Welding Services Stand Out?
1. Advanced Process Control
Pre-heat & Post-weld Treatment:
Induction heating (up to 300°C) to prevent HAZ cracking.
Stress-relief annealing (AWS D1.1 compliant).
Seam Consistency:
Laser-guided robotic welders: ≤0.5mm bead deviation.
2. Uncompromising Quality
NDT Testing:
100% Visual (VT).
Magnetic Particle Inspection (MPI) for surface cracks.
Fatigue Life Validation:
Simulate 50,000+ operational cycles (ISO 12107).
3. Customization Flexibility
Low-Volume Expertise: Prototype batches (1-10 units) with full documentation.
Large-Scale Capacity: Monthly output 200+ tons for OEM contracts.
Industry Challenges We Solve
● Warpage Control:
Fixture-based jigging + intermittent welding sequence minimizes distortion on large plates.
● Corrosion Protection:
Post-weld galvanizing/zinc spraying (ISO 1461) for coastal/chemical exposure.
Certifications & Compliance
● Welder Qualifications: AWS CWI certified, EN 287-1 (ISO 9606).
● Material Traceability: Mill test reports (EN 10204 3.2) + heat number tracking.
Efficient Project Execution
1. Design Review: Optimize weld joints for manufacturability (DFM).
2. Process Planning: Select filler metals (ER70S-6, 309L) based on stress analysis.
3. Production: JIT delivery with real-time WIP tracking.
4. Documentation: Provide WPQR (Weld Procedure Qualification Record) + IWI (Inspection Report).
Key Differentiation
● Focuses on engineering-grade welding beyond basic fabrication.
● Quantifies performance metrics (fatigue cycles, scrap rates) for ROI clarity.
● All welding seams must meet customer specifications to reduce buyer risk.
