ABSTRACT:
A tool for grinding irregular surfaces such as transition welds includes a base adapted to rest on the surface of the workpiece, a track on the base and a carriage which moves longitudinally of the weld with one end on the track and the other end of the carriage having a roll which contacts the top of the workpiece. A trolley is supported on the carriage for transverse movement and carries a grinding wheel and its motor. Guide tracks on the carriage cause the grindling wheel to move in a non-linear path. The base is placed in position and the grinding wheel is reciprocated transversely as the carriage reciprocates longitudinally. If the weld is longer than the carriage movement, the base is moved after the grinding is finished at the first position to a second position adjacent thereto and the operation is repeated until the weld is completely ground as desired.
