HANGZHOU NUZHUO TECHNOLOGY GROUP CO.,LTD.

Experts recommend nitrogen purity levels between 99.5% and 99.999% for laser welding applications. This high-purity nitrogen prevents oxidation, reduces porosity, and ensures a clean, smooth weld finish—advantages that compressed air simply cannot match. Unlike air, which contains oxygen and moisture that can degrade weld quality, nitrogen creates an inert environment that enhances both structural integrity and visual appeal.

Pressure Swing Adsorption (PSA) technology has become the industry standard for on-site nitrogen generation. These systems work by passing compressed air through a carbon molecular sieve (CMS), which selectively adsorbs oxygen and other impurities, allowing high-purity nitrogen to flow through. The process is energy-efficient, cost-effective, and capable of delivering a continuous supply of nitrogen tailored to specific welding requirements.

For over 20 years, Hangzhou Nuzhuo Technology Group Co.,Ltd. has been a global leader in nitrogen generation solutions, serving laser welding companies across multiple industries. With a strong reputation for reliability, our PSA nitrogen generators are backed by CE, ISO, and other international certifications, ensuring compliance with the highest industry standards. Our competitive pricing and extensive export experience—spanning numerous countries—make us a preferred partner for businesses seeking high-performance nitrogen solutions.
