Overview of Application Fields of Nitrogen Generator
Nitrogen generators are widely used in various fields that require inert gas protection. Whether it is nitrogen blowing in laser welding, packaging protection of electronic components, or controlled atmosphere packaging in food preservation, nitrogen generators can provide stable and reliable nitrogen supply. Based on our export experience, the demand for nitrogen generators is mainly concentrated in six areas: laser welding, electronic components, automotive manufacturing, aerospace, chemical industry, and food and medicine. The requirements for nitrogen purity, flow rate, and pressure vary in each field.
laser welding
Laser welding is one of the main application areas of nitrogen generators. During laser welding, nitrogen serves as a protective gas, which can effectively prevent weld oxidation, improve welding quality and stability.
Technical requirements:
- Nitrogen purity: ≥ 99.999%
- Dew point: ≤ - 60 ° C
- Flow rate: adjusted according to welding power and speed
- Pressure: 0.3 - 0.6 MPa
High purity nitrogen can ensure that there are no impurities interfering with the welding process, the weld seam is purer, and the welding strength is higher. Our laser welding dedicated nitrogen generator adopts advanced pressure swing adsorption technology, which can stably output high-purity nitrogen gas.
