ABSTRACT:
A weld sander for smoothing the surface of a weld which joins lengths of pipe. The weld sander has a carriage which travels around the pipe and movably mounts a head carrying a grinding belt, with the belt mounted for movement toward and away from the weld and also for tilting movement. Pipe followers, associated with the head, control the minimum distance of the belt from the pipe sections and, additionally, establish a minimum distance between an edge of the belt and a pipe to prevent engagement between the belt and a pipe when the belt tilts.
