What is laser cutting?
Laser cutting, which originated in the mid-1960s, is a cutting process characterized by the use of an amplified laser as a "tool" and the use of a computer-controlled program to perform cutting operations.
CO2 laser is mainly used in laser cutting, neodymium (Nd), yttrium aluminum garnet (Nd: YAG) and fiber laser, the laser has its own advantages and disadvantages, for example, CO2 laser is the ideal choice of the cutting and carving, Nd more suitable for laser cutting applications that need a lot of energy and fiber laser is replacing other lasers, get more and more widely used.
What is plasma cutting?
Plasma cutting originated in the 1950s and is another cutting method characterized by the use of plasma torches.A plasma torch produces a flow of plasma heat that can melt the hardest materials.
Plasma cutting does not use fire or flame, but instead USES electrically conductive ionized gas, also known as plasma.Plasma can reach very high temperatures, such as 20,000 degrees Celsius.
Plasma-cutting workers must wear appropriate personal protective equipment to prevent arc eyes, also known as photokeratitis or ultraviolet keratitis, which is an injury that occurs when workers' eyes are exposed to high doses of radiation.Because plasma torches emit radiation, workers have to wear goggles.
Both laser cutting and plasma cutting can cut metal workpiece in completely different ways.Laser cutting USES an amplified laser, while plasma cutting USES plasma.
