FRICTION WELDING: WHAT IT IS AND HOW IT WORKS

IN THEORY, ALL DUCTILE METALS COULD BE COLD PRESSURE WELDED BUT THE FORCES NEEDED WOULD BE PROHIBITIVE. THEREFORE MATERIALS WERE HEATED TO IMPROVE DUCTILITY, ALLOWING PRESSURE WELDS TO BE MADE WITH LOWER FORCES. SEVERAL HEATING METHODS ARE USED COMMERCIALLY SUCH AS FLAME HEATING, INDUCTION, RESISTANCE, AND MORE RECENTLY FRICTION. APART FROM BEING A VERY EFFICIENT HEAT SOURCE, FRICTION PROVIDES AN EFFECTIVE CLEANING ACTION, REMOVING THE SURFACE CONTAMINATION WHICH PREVENTS METALS FROM BONDING TOGETHER. WORK CARRIED OUT AT THE WELDING INSTITUTE AND BY MANUFACTURERS OF EQUIPMENT HAS DEMONSTRATED THAT FRICTION WELDING PROCESSES ARE IDEALLY SUITED FOR JOINING MANY MATERIALS IN SIMILAR AND DISSIMILAR COMBINATIONS AND IN NUMEROUS CONFIGURATIONS. AS WELL AS BEING TECHNICALLY SUPERIOR TO OTHER WELDING PROCESSES CONTINUOUS DRIVE FRICTION WELDING OFFERS MANY ECONOMIC ADVANTAGES, EVEN THOUGH EQUIPMENT COSTS ARE RELATIVELY HIGH. /AUTHOR/
