carbon steel
As carbon is contained in carbon steel, the laser reflection is not strong and the beam absorption is very good. Carbon steel is suitable for laser cutting of all metal materials. Therefore, the position of carbon steel laser cutting machine in carbon steel processing is unshakable.
Carbon steel is used more and more widely. Modern laser cutting machines can cut carbon steel plates with a maximum thickness of 20mm. The slit of carbon steel can be controlled in a satisfactory width range through the oxidation melting cutting mechanism. To about 0.1mm.
stainless steel
Laser cutting stainless steel uses the energy released when the laser beam irradiates the steel plate surface to melt and evaporate stainless steel. Laser cutting stainless steel is a fast and effective processing method for the manufacturing industry with stainless steel sheet as the main component. The important technological parameters affecting the cutting quality of stainless steel are cutting speed, laser power, air pressure, etc.
Compared with carbon steel, stainless steel cutting requires higher laser power and oxygen pressure. Although stainless steel cutting achieves satisfactory cutting results, it is difficult to obtain joints without adhesive residues. The method of laser beam coaxial injection blows away the molten metal, so no oxide is formed on the cutting surface. This is a good method, but more expensive than traditional oxygen cutting. One way to replace pure nitrogen is to use filtered plant compressed air, which contains 78% nitrogen. When laser cutting mirror stainless steel, in order to prevent serious burns to the plate, laser film is required
Aluminium and alloys
Although laser cutting machine can be widely used for processing various metal and non-metallic materials. However, some materials, such as copper, aluminum and their alloys, are difficult to process due to their own characteristics (high reflectivity).
At present, laser cutting of aluminum plate is widely used by fiber laser and YAG laser. The two kinds of equipment, whether cutting aluminum or other materials, such as stainless steel and carbon steel, have good performance, but cannot process thick aluminum. Generally, the maximum thickness of 6000W can be cut to 16mm, 4500W can be cut to 12mm, but the processing cost is high. The auxiliary gas used is mainly used to blow the molten products away from the cutting area, which can usually obtain better cutting quality. For some aluminum alloys, care should be taken to prevent microcracks on the slit surface.
Copper and alloys
Pure copper (red copper) cannot be cut by CO2 laser beam due to its high reflectivity. Brass (copper alloy) uses higher laser power, and auxiliary gas uses air or oxygen to cut thinner plates.
Titanium and alloy
The laser cutting quality of titanium alloys commonly used in aircraft industry is good. Although there will be some sticky residue at the bottom of the gap, it is easy to clean. Pure titanium can be well coupled with the thermal energy generated by focused laser beam conversion. When the auxiliary gas uses oxygen, the chemical reaction is violent and the cutting speed is fast. However, it is easy to form oxide layer on the cutting edge. It can also cause excessive combustion inadvertently. For stability, it is better to use air as auxiliary gas to ensure cutting quality.
Alloy steel
Most alloy structural steel and alloy tool steel can obtain good trimming quality through laser cutting. Even for some high-strength materials, as long as the process parameters are properly controlled, a smooth and non viscous slag dressing can be obtained. However, for high speed tool steel and hot work die steel containing tungsten, corrosion and slag will occur during laser cutting.
Nickel alloy
There are many varieties of nickel base alloys. Most of them can be oxidized, melted and cut.
