Laser cutting


Laser cutting with laser melting cutting of the difference lies in the use of oxygen as a cutting gas. With the interaction between oxygen and the metal is heated, that initiates further heating of the material. Because of this effect, for the structural steel of the same thickness, using this method can obtain higher cutting rate than melting cut.


The other hand, the method of cutting and melting may cut quality is worse than. In fact it produces a wider slot, apparent roughness, increasing the heat-affected zone and edge quality. Laser cutting in machining precision model and sharp corners are bad (burn dangers of sharp corners). Laser pulse mode can be used to limit heating, laser power decided to cut speed. In the case of laser power, limiting factor is the oxygen supply and the thermal conductivity of the material.
