1. Process description
This process applies to bead welding the thermal effect created by the friction of a tool consisting of a revolving metal rod (or tip) fitted with reliefs and driven in rotation at high speed. The heat generated locally brings the metal to a pasty state, allowing the tool to plunge into the material and then move along the joint where it progresses like the "keyhole" of a high-energy beam
This is a progressive welding process, as opposed to conventional friction welding, which is known elsewhere
It competes directly with all other continuous fusion welding processes (arc, high-energy...

Most of the data concerning the process can be found at the British Welding Institute, TWI, and the French Welding Institute, IS.
The process is currently the subject of numerous research and development programs financed by companies and institutes, some of which are French (aeronautics, railways, etc.). They cover all aspects of the process: scientific, technological, economic and practical. All...
