The Role of Nitrogen in Laser Welding: Achieving Silver-Bright Welds with RIVOMACH PSA Technology
Maximize solderability and prevent re-oxidation. Discover the technical specifications and operational secrets of high-purity nitrogen generation.
1. Why Nitrogen is Essential for Professional Welding
In the precision world of laser welding, Nitrogen (N2) is one of the most critical reactive gases. Its primary function is to displace oxygen from the welding zone. By creating an inert atmosphere, it effectively:
- Prevents re-oxidation of the welding spot.
- Enhances solderability by ensuring clean surfaces.
- Works with flux to improve wetting conditions, creating a smooth, silver-bright bead.
2. Professional Technical Monitoring
RIVOMACH PSA Nitrogen Generators are equipped with precision gauges to ensure 24/7 stability. Understanding these values is key to high-quality output:
Air Pressure Gauge
Monitors intake air. Normal range: 0.6 – 0.8 MPa. Essential for the PSA cycle.
Tower A/B Gauges
Monitors Carbon Molecular Sieve tanks. Only one tower operates while the other depressurizes.
Programmable Time Relay: Pre-set at the RIVOMACH factory for optimal Tower A/B switching cycles. No user adjustment needed.
3. Operation Guide & Best Practices
A reliable machine requires correct operation. Follow the RIVOMACH standard protocol:
- Connect compressed air (must be water and oil-free).
- Ensure air pressure is within 0.6-0.8 Mpa.
- Switch on power; Tower A and B will begin alternating adsorption.
- Initial Purge: For the first run, discharge air for 40-50 minutes to ensure target purity.
- Shutdown Logic: Close all nitrogen valves first, then turn off power. This maintains peak pressure for a faster purity rise during next start-up.
IMPORTANT: Never exceed rated temperature or pressure. Always use an air dryer/filter before the nitrogen inlet.
