发明名称 Apparatus and method for internally weld-cladding pipe elbows
摘要 The weld-cladding apparatus includes a turntable which is rotatably mounted in a yoke about a horizontal axis. An outrigger is mounted on the yoke and has a curvature coincident to the curvature of the torus-to-be-cladded and a center of curvature on the axis of the turntable. The weld-cladding means is rotatably mounted at the end of the outrigger in a vertical plane common to the plane in which the pivot axis of the turntable moves during rotation of the yoke. During use, the weld-cladding means remains vertical while the turntable pivots on the horizontal axis. In order to form a weld, the turntable is oscillated back and forth about the pivot axis over an arcuate length equal to the length of the torus. The turntable is tilted incrementally a distance equal to the width of a weld.
