Season's greetings 2015 - innovation nitrogen for in laser cutting

Nitrogen generation for laser cutting

Generating nitrogen on-site for laser applications can be cheaper and safer.

Why use nitrogen for laser cutting?

  • Prevents oxidation: Thanks to its inert properties, nitrogen allows the laser to operate in an oxygen-free environment without the risk of oxidation. When your application heats up and comes in contact with oxygen, a phenomenon known as oxidation occurs. This can cause a carbon layer to form on the cut edge resulting in issues such as poor product finish and adhesion problems for any coating or paint applied to the oxidised surface. 
  • Helps purge laser beam: To prevent the beam from distorting and to maintain power and intensity, the beam path needs to be kept clear of dirt particulates and any other contaminants that could cause it to diverge or lose power. Nitrogen is the ideal medium to use for beam guide-way purging as it is dry, clean, oil-free and has a very low contaminant content.

What are the benefits of using nitrogen generators for your laser cutting application?

  • Lower cost: Nitrogen assist and purge gas are some of the highest costs when it comes to laser cutting, particularly for fibre lasers . So any savings that will be made as a result of generating your own nitrogen will positively affect your bottom line. 
  • Higher productivity: By saving the time that is normally spent on changing tanks, you will ensure that your application runs continuously and without much attention from the operator. 
  • Better control:  Generating your own nitrogen means no more ordering, changing and running out of bottles. No more liquid deliveries interrupting production, and you no longer have to  deal with suppliers' unpredictable price increases.
  • Highest efficiency:  No oxide edge, high purity 99.999% gas available.
  • On demand nitrogen: This plug and play solution is sized to match your laser cutter, so you never need to  empty your bottles and  refill during valuable production hours
  • Plug and play solution: No need to buy separate compressors and equipment. Easily modified and upgraded if production increases as well as other benefits

What type of nitrogen generation packages are available to you ?

  • A cylinder filling system that is designed to produce a small amount of gas on a continuous basis and then compress it to high pressure (300 – 350 bar g) for storage in a high pressure storage bank(s). This type of system is ideal for intermittent usage or where demand can fluctuate from high to low flow requirements frequently. Typically, a contract laser cutting job shop would benefit from this type of installation.
  •  A gas on demand system that is designed to meet the maximum flow requirement of the application with a small buffer stored at 40 bar .
