Title of Invention

A MACHINE FOR OVERLAY WELDING ON SHORT RADIUS ELBOW SURFACES

Abstract Special purpose welding overlay equipment comprising a turntable with a top plate, clamping fixture consisting of top and bottom claiming plates, said bottom clamping plates being placed on and tacked welded to the said top plate by matching its centerline with object's mean radius, the said top and bottom plates are then clamped together, the vertical pipe arm bolted to the said turntable, the pipe sleeve being sliding over said vertical arm, one end of horizontal pipe arm being welded to the said sleeve at right angle and the other end being welded to the curved pipe arm horizontally, at open end of curved pipe arm a swivel plate mechanism is welded and then welding torch mounted on it thereby making short radius elbows being tilted to any desired angle and thus making it possible to carry out overlay welding using submerged arc welding and flux cored arc welding process.
