Friction Welding                                           

The advantages are both metallurgical and physical. A bonded joint is formed using no filler metal, flux or shield gas. The process is environmentally clean; no arcs, sparks, smoke or flames are generated by clean parts. Surface preparation/cleanliness is not significant with most materials since the process burns through and displaces surface impurities. During the friction welding process there are narrow heat affected zones. The process is suitable for welding most engineering materials and is well suited for joining many dissimilar combinations. In most cases, the weld strength is as strong or stronger than the weaker of the two materials being joined. Operators are not required to have manual welding skills. Friction welding requires only simple integration into the manufacturing area. The process is easily automated for mass production. Welds are made rapidly compared to other welding processes. Plant requirements (space, power, special foundation etc.) are minimal for the friction welding process.
