Precision Fabrication for Global Industries
1. Core Manufacturing Processes
Our stainless steel welding integrates advanced techniques to ensure corrosion resistance, structural integrity, and aesthetic excellence:
🔧 Key Welding Methods:
-
TIG (GTAW) Welding
-
For aerospace, medical & food-grade applications (e.g., pipes, vessels).
-
Argon shielding gas | Precision heat control | Autogenous welds possible.
-
-
MIG (GMAW) Welding
-
High-speed fabrication of structural components (racks, frames).
-
Pulsed MIG for thin sheets (<1mm) | Low spatter.
-
-
Laser Hybrid Welding
-
Automotive/exhaust systems | Seamless high-strength joints | ≤0.1mm precision.
-
-
Plasma Arc Welding (PAW)
-
Critical thickness control (e.g., pressure vessels).
-
⚙️ Ancillary Processes:
-
Post-Weld Treatment
-
Pickling & Passivation: Restore corrosion resistance using HNO₃/HF solutions.
-
Electrochemical Polishing: Mirror finishes for sanitary applications (ISO 9001/ASME BPE compliant).
-
-
Distortion Control
-
Jig/fixture optimization | Step-back welding sequence | Thermal stress simulation.
-
2. Critical Technical Challenges & Solutions
| Challenge | Root Cause | Our Solution |
|---|---|---|
| Heat-Affected Zone (HAZ) Corrosion | Chromium carbide precipitation | ▶ Low-carbon grades (316L) ▶ Laser overlay welding ▶ Interpass temp ≤150°C |
| Warping/Deformation | Uneven thermal expansion | ▶ Modular clamping systems ▶ Pre-set counter deformation ▶ Robotic pulse welding |
| Porosity & Cracking | Contamination (O₂, S, oils) | ▶ Triple-stage degreasing ▶ Ultra-dry shielding gas (dew point -60°C) ▶ Ferrite control (FN 4-12) |
| Weld Discoloration | Oxide layer formation | ▶ Back-purging (O₂ < 0.1%) ▶ Post-weld electropolishing |
| Thin-Gauge Burn-Through | Excessive heat input | ▶ Pulsed arc technology ▶ 0.3-1.0mm auto-gap compensation |
