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 cutting each piece needs to be ground using a heavy duty grinding wheel to remove rough edges in both sides and all mill scale. Often directional grinding is used to produce more interesting patterns to enhance the design. Only after this will the piece by ready for color options.
An acetylene torch is used to heat the finished piece. Depending on how long heat is applied to an area, different colors are rendered.
