Today, again to share the day of the laser device instructions.
About optical fiber laser cutting machine for cutting the auxiliary gas, believe that you will use to the gas.
Why, then, using a gas?
And how to choose a gas?
Today, we would like to discuss together.
in figuring out how to choose fiber laser cutting machine auxiliary gas before, must first understand why want to use the function of auxiliary gas and auxiliary gas. On this point, China laser laser equipment factory give you concluded:
the use of optical fiber laser cutting machine auxiliary gas in addition to blow away the coaxial slotted in slag, can also cool processing surface, reduce the heat affected zone, cooling focusing lens, prevent dust from entering the lens holder in pollution lens and cause the lens overheating; In addition, some cutting gas can also protect the parent metal. Selection of gas pressure and the influence of cutting technology, choose the kinds of auxiliary gas to the cutting performance, such as cutting speed, cutting thickness have influence.
so, must be added in the process of laser cutting and tubing laser cutting machine cut the material for the auxiliary gases. Coaxial gas in addition to blow away the slot in the slag, can also cool processing surface, reduce the heat affected zone, cooling focusing lens, prevent dust from entering the lens holder in pollution lens and cause the lens to overheat. So, choose the kind of auxiliary gas optical fiber laser cutting machine for cutting performance, such as cutting speed, cutting thickness have influence.
so, to the auxiliary gases of different fiber laser cutting machine, and how should we choose? The following points, you may wish to taste slowly. A, oxygen O2
it is mainly used for laser cutting machine for cutting the carbon steel. Oxygen reaction heat can be large-format not only improve the efficiency of cutting, and the oxide film will improve the beam spectrum absorption factor of reflective materials. Incision face black or dark yellow. 【 Mainly used 】 Rolling steel, welding structure with rolled steel, mechanical structure with carbon steel, high tension, tool plate, stainless steel, galvanized steel, copper and copper alloy, etc.
2, nitrogen N2
some metal cutting when using oxygen, oxygen oxidation film formed on the surface of the cutting. With nitrogen can avoid the appearance of oxide film, no oxidation for cutting. So, it can directly for welding, daub, has the characteristics of strong corrosion resistance. Incision face pale.
【 Mainly used 】 Stainless steel, galvanized steel, brass, aluminum, aluminum alloy, etc. Three, air
due to the air can be provided directly by the air compressor, so the price is very cheap compared with other gases. Though we know, containing about 20% of the oxygen in the air, but the cutting efficiency is much less oxygen, cutting ability should be close to nitrogen. When cutting, the surface will appear trace of oxide film, but can be used as measures to prevent a coating layer falls off. Incision face yellow.
【 Mainly used 】 Aluminum, aluminum alloy, stainless steel, brass, galvanized steel and nonmetal, etc.
4, inert gas & ndash; — Argon Ar
argon gas is inert gas, can be used to prevent oxidation during laser cutting and the nitride, also can be used in the welding. However, it compared with other fiber laser cutting machine auxiliary gas, high prices, will increase the cost. Incision face pale.
【 Mainly used 】 Titanium and titanium alloy etc. See this,
do you have a feeling of suddenly?
laser equipment factory professional laser equipment manufacturer in China, in addition to the recommended today 3 d laser marking machine, and 1000 w laser cutting machine, laser marking machine, laser engraving machine, etc.
