The plasma is a gas which is ionized and high heated in the
arc and therefore changed physical properties. For example it is used for cutting
of materials. The plasma jet which is necked through arc, produced at the plasma
torch, produces temperatures from 10000 up to 20000 Kelvin.
Non-ferrous metals and steels can be cut with the plasma (high cut speed and smooth
cut fugue). Hereby the material becomes melted and is blown out of the fugue. The
cutting device is water-cooled and operates with inert gas and direct current.
It becomes leaded from hand or it is moved from automatic controled devices. The
method is fundamental for all fusible materials applyable. Steels up to thickness
of 120 mm can be separated.
The examination contained in this report is made at a wire
rod with the material number 1.6582.
