لماذا يجب أن نستخدم الغاز الإضافي عندما نستخدم آلة القطع بليزر الألياف

لماذا نحتاج إلى غاز إضافي عندما نستخدم آلة قطع ألياف الليزر لقطع المواد المعدنية؟

There are 4 reasons.

1. Firstly.The auxiliary gas will start chemical reaction with the metal material.It will increases the working capacity.
2. Secondly.Blowing off the slag by air and clean the cutting seam.
3. Thirdly.The gas will cool the area around cutting seam.It can avoid shape change of the material.
4. Last but most importantly.To protect the Focus Lens from combustion products caused by high temperature of laser beam.

Normally,O2 ( Oxygen).N (Nitrogen) and Air will be used as auxiliary gas for fiber laser cutting machine.

وظائفهم هي كما يلي على التوالي.

N: نيتروجين is used for cutting nonferrrous metal.

For example stainless steel and Aluminum sheet.

It can cool and protect the material.As such materials are easy to be blackened with Oxygen.

Using Nitrogen can avoid this phenomenon of going black.

Aluminum.Aluminum Alloy.Stainless Steel.Galvanized Steel Sheet.Brass.

O2: الأكسجين يستخدم في قطع الكربون الصلب.

As there is many Carbonaceous impurities in carbon steel.

Using O2 can greatly increase the combusting speed.

It can also accelerat cutting speed.However.

There is a disadvantage.The cutting surface will be black.
