The method typically used is called a “flash-butt process”. The process is done in a large welder that grips the ends of the rim in clamps to hold and guide the rim during welding. The rim blank is rolled and cut with extra length circumferentially. The rim is clamped in the welder dies with the ends of the rim protruding about ¼ from the die on each side. The welder then starts the “flash” part of the weld cycle. It passes very high amperage current through the clamp dies while slowly moving one die to bring the ends of the rim together. The current creates an arc between the ends of the rim, burning off the extra metal allowed in the cutting of the rim blank while heating the ends of the rim. After a precisely controlled flash time, the current is turned off and the “butt” part of the weld cycle is initiated. This consists of rapidly forcing the heated ends of the rim together with great force to complete the joint. There is weld flash left around the weld that is removed to smooth the joint and blend it in to the extrusion shape Buy Sun Ringle Wheels & Tyres from Chain Reaction Cycles, the World's Largest Online Bike Store.
