Tig Welding, otherwise known as GTAW, is generally used to weld exotic material like stainless steel, aluminum, copper, titanium and critical welds that must be flawless such as aircraft engine parts. Tig welding offers the user the greatest amount of flexibility to weld the widest range of material.
Powder coating is a type of coating that is applied as a free-flowing, dry powder. The main difference between a conventional liquid paint and a powder coating is that the powder coating does not require a solvent to keep the binder and filler parts in a liquid suspension form. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin". It is usually used to create a hard finish that is tougher than conventional paint.
Here at RCR we have put our water jet through it's paces cutting a multitude of different materials, metal being the most common, but also wood, paper, rubber, foam, fiberglass, acrylic, granite, marble, limestone, tool steel, tile and plastic. Pretty much the only things we can't cut are tempered glass, diamonds, and certain types of ceramic.
Welding is a fabrication or sculptural process that joins materials, usually metals, by causing fusion, which is distinct from lower temperature metal-joining techniques such as brazing and soldering, which do not melt the base metal. In addition to melting the base metal, a filler material is often added to the joint to form a pool of molten material (the weld pool) that cools to form a joint that can be as strong as the base material.
