Boutet welding process for rail joints, which uses the "aluminothermie", has been advanced to a three piece mold, which permits the welding of joints, even over the ties without moving them aside, and the use of a small portable machine for making the molds. This makes possible the speedier welding of joints at the rate of a joint per man-hour or less. Technical advantages of being able to center accurately all parts of the mold around the joint, and the practical elimination of any bead under the flange. Limited preheating welding (a rapid process) has been developed to minimize the effect of rail movement during the welding preparations. The elimination of the bead has made possible a high quality joint, highly resistant to the drop and fatigue tests.
