Background
The door and window industry heavily uses galvanized steel tubes (1.2–2.0mm) and stainless steel tubes for frames and security grilles. Traditional TIG or MIG welding inputs too much heat, causing deformation that leads to poor fit and requires grinding. Laser welding solves this perfectly.
Solution Specs
| Item | Details |
|---|---|
| Machine Model | Zhijie MJ-10-BFL / MJ-15-BFL |
| Laser Source | 1000W / 1500W fiber laser |
| Wire Feeder | Standard auto wire feeder |
| Shielding Gas | CO₂ (galvanized) / Argon Ar (stainless) |
| Welding Material | Galvanized steel tube 1.2 – 2.0mm / stainless steel tube |
| Welding Type | Fillet joint, T-joint, butt joint |
Key Results
| Metric | Traditional TIG | Laser | Improvement |
|---|---|---|---|
| Heat Deformation | 0.5 – 1.5mm | ≤ 0.1mm | No grinding, install directly |
| Welding Speed | ~ 80 mm/s | ≥ 250 mm/s | 3x faster |
| Zinc Layer Burn-off | Significant, needs repaint | Minimal, mostly preserved | Less anti-corrosion work |
| Weld Appearance | Rough, needs grinding | Smooth, no grinding | 100% labor saved |
