Laser Cutting

Description

Laser cutting is mainly a thermal process in which a focused laser beam is used to melt material in a localised area.
There are three major varieties of laser cutting: fusion cutting, flame cutting and remote cutting.
In fusion cutting, an inert gas (typically nitrogen) is used to expel molten material out of the kerf.
In flame cutting, oxygen is used as the assist gas.
In remote cutting, the material is partially evaporated (ablated) by a high-intensity laser beam, allowing thin sheets to be cut with no assist gas.
