Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, Stainless steel, aluminum, brass and copper, although other conductive metals may be cut as well. Plasma cutting is often used in fabrication shops, automotive repair and restoration, industrial construction, and salvage and scrapping operations. Due to the high speed and precision cuts combined with low cost, plasma cutting sees widespread use from large-scale industrial CNC applications down to small hobbyist shops.
After each piece is plasma cut it needs to be ground to remove rough edges and is also part of the artistic process creating unique effects.
An acetylene torch is used to heat the finished piece. Depending on how long heat is applied to an area, different colors are rendered.
