Adapting Metal Cutting to Higher Power, Higher-Speed Lasers- minimum laser power to cut metal building ,Oxygen is a heat accelerant with the heat providing additional power. Nitrogen being a cold cut requires additional wattage and gas flow, according to Cotton. Cutting 1" (25.4 mm) mild steel with oxygen means using at minimum a 5 kW laser. Using nitrogen with a 5 kW laser limits the thickness to 5/16" (7.9 mm). “That is a big difference ... Laser Cutting Thickness Guide on Laser Power, Lens and ... - amGeneral speaking, the laser cutting machines require to achieve laser efficiency higher than 90% with laser beam travel distance less than 3 metres. #2 There is no absorption problem of laser light from either a Nd:YAG (1.06 microns) or CO2 (10.6 microns) laser in nitrogen, or in air without contaminants.
Carbon Steel. Carbon steel is an exceptionally strong, dense material that requires high energy to in order perform laser cuts. Suffice it to say that the thicker the steel sheet, the more power will be required. CO2 lasers have the capacity to achieve higher laser cutting power. With settings of 6000 watts, a CO2 laser can penetrate carbon ...
For the sake of naming a specific number, we can pair a high wattage laser — 6,000 watts — with a metal like stainless steel. In this case, the laser cutting maximum thickness would typically be about 2.75 inches. But that thickness is contingent on those particular variables. The same laser paired with carbon steel could probably only ...
It depends on the metal type, its thickness, and the power of the laser machine. For instance, the cutting speed of a 1000 W laser machine for carbon steel 0,5-8,0 mm thick will be around 0,6-15 m/min, for stainless steel 1,0-5,0 mm thick will be 0,8-18 m/min, for aluminum 1mm thick – 1,2-10 m/min, and for copper 1mm thick – 10 m/min. Power.
A possible solution for laser cut aluminum and laser cut steel, involves the use of a higher power setting coupled with compressed gas technology. Using gases in conjunction with cutting operations is fairly common. Nitrogen and oxygen assisted laser cutting machines can shape aluminum and stainless steel at relatively high capacities and with ...

We sell different types of metal laser cutter, include fully enclosure metal sheet laser cutter and auto sheet exchange for steels and aluminum laser cutter, and we have ...
Sheet metal cutting requires a power density of 10 6 watts/in 2 (source: Mike Klos @ laser mechanisms) Converting to millimeters, that' 1550 watts/mm 2. (using equation: 1in 2 = 645mm 2 ) A 100 watt laser can achieve a power density of 1550 watts/mm 2 in a spot size that is 0.6452mm 2 A spot size that is 0.6452mm 2 has a diameter of of .28mm or 280 micron (using area = pi * (d/2) 2 ) 280 micron!

The most important criterion when selecting the laser power of your laser machine is the application that you want to use most often with the laser. If the laser is primarily used for engraving, you will achieve good results with laser powers between 25 and 80 watts. For laser cutting or for very high speed applications, we recommend a laser ...
Cover the piece with vinyl foil (or nail polish, if it' small). Use laser to ablate the coating. Then do electro-etching in salt. If you want to directly engrave metal you'll need a crazy laser setup, 100W at least. 3. level 2. Op · 6 yr. ago. I was actually looking at 100w, but was hoping I could get away with something less.

The optimum laser power for cutting applications. High laser powers are the secret to achieivng quality cut results for thick materials. As a rule of thumb, acrylic requires 10 watts per millimeter (of thickness). So a 10mm thick acrylic sheet is best cut with a 100w laser or greater. A comparison of the cutting time for different sheet ...

Laser cutting power to penetrate one inch of stainless steel requires 4,000 watts. Aluminum However, it is a light-reflective and heat-conductive metal that requires proper mixture of compressed gases to achieve efficient laser cuts.
In other words, the maximum thickness that can be cut by the same power laser cutting machine is also different. For example, a 1000W laser cutting machine can cut 10mm thick carbon steel, but only 4mm stainless steel. Of course, when the laser power is fixed, the thinner the plate, the faster the cutting speed.
For instance, the cutting speed of a 1000 W laser machine for carbon steel 0,5-8,0 mm thick will be around 0,6-15 m/min, for stainless steel 1,0-5,0 mm thick will be 0,8-18 m/min, for aluminum 1mm thick – 1,2-10 m/min, and for copper 1mm thick – 10 m/min. Power.

The aluminum plate laser cutting machine has high precision, the laser cutting incision is narrow and smooth, and there is no fillet and common rough mouth of mechanical blanking; The heat affected zone, thermal stress and thermal deformation are small. 2. The laser cutting machine has fast cutting speed. 3.
These require high powers of 200 or 400 watts in order to be able to cut them cleanly even with a comparatively low thickness of 2 and 3 mm. The optimum laser power for cutting applications Even with a fiber laser, the main application is crucial when it comes to choosing the right laser power. High laser powers are required when engraving metals.
For example, a 1000W laser cutting machine can cut 10mm thick carbon steel, but only 4mm stainless steel. Of course, when the laser power is fixed, the thinner the plate, the faster the cutting speed. In this case, the laser cutting thickness and speed are inversely proportional.
To cut metal, you will need, at least, a 150 W machine with oxygen assist. It is also important to keep in mind that most CO2 lasers, can’t handle the laser being reflected back into the laser emitter. That’s why CO2 lasers in the 150-300 W range are good to work on steels that aren’t too reflective. Engrave better with Endurance lasers!
