Stainless steel PK carbon steel which metal is the most suitable for 1000w laser cleaning machine?

1000w laser cleaning machine  processing metal, the most widely used material is stainless steel and carbon steel, compared to aluminum alloy, brass and other high reflective metal, the two metal absorption of light is better, so the use of laser cutting is more widely.

Powerful metal laser cleaning machine, in the processing of stainless steel and carbon steel and what will be different, what is the most suitable material for laser cutting machine cutting processing? To battle ~

The cutting process is very different

Using a laser cutting machine processing stainless steel, stainless steel contains 10% to 20% of chromium, iron and chromium are prone to oxygen cutting the exothermic reaction, including chromium oxide have prevent oxygen into the internal features of molten material, and reduce the amount of oxygen the melt into the layer, incomplete melting layer oxidation, reduction reaction, to lower cutting speed.

Using a laser cutting machine processing of carbon steel, usually using oxygen as aided gas, more than 99% on the low carbon steel cutting is iron, iron oxide reflect also can produce a large amount of heat, using oxygen as auxiliary, can reduce the requirement for laser energy, and the oxide of low viscosity, melting point to adhere to the surrounding steel adhesion is low, Such slag is also easily blown apart by oxygen, leaving a smooth cut surface with no residue.

Different materials processing skills

Laser cutting mirror stainless steel, in order to prevent serious burns plate, need to stick laser film. Even though it's protected by film, there's still a little bit of scalding around the edges. At this point, the laser cutting process parameters need to be strictly controlled in the processing process to maintain good corrosion resistance of such materials. The most important process parameters affecting the cutting quality of stainless steel are cutting speed, laser power, oxygen pressure and focus.

With the improvement of cutting machine power, laser cutting machine can process more and more thick carbon steel, in the cutting of relatively thick low carbon steel plate, you need to use a larger diameter nozzle and low pressure oxygen pressure, so as to prevent cutting will burn the edge of the cut.

上料

Compared with low carbon steel, stainless steel cutting requires higher laser power and oxygen pressure, while stainless steel cutting to achieve a more satisfactory cutting effect, but it is difficult to obtain a completely non-sticky slagging. Using inert gas as auxiliary gas cutting stainless steel can be obtained without oxidation cutting edge, directly used for welding, but its cutting speed and oxygen as auxiliary gas compared to play reduced about 10%.

系统

Compared to the traditional processing methods, laser cutting machine machining efficiency is higher, can achieve mass production, and therefore application more and more widely in the processing of stainless steel, carbon steel, two kinds of metals are suitable for laser cutting processing, but presents the machining efficiency and machining quality, then you need to trial and error adjustment makes equipment to achieve the best state.
