COMBINED INDUCTION HEATING AND COATING SYSTEM FOR PIPE WELD JOINTS Abstract of the Disclosure An apparatus and method for heating and coating a section of a pipe comprising a plurality of induction type heaters supported in spaced circum- ferential relation around the pipe section, the heaters having relatively flat and hollow induction coils therein, the coils of the induction heaters being oriented in a cylindrical surface adjacent to, and parallel with, the surface ofthe pipe, a coating dispenser mounted between a pair of induction heaters for dispensing a coating material on the surface of the pipe, the heaters and dispenser being rotated as a single assembly around the pipe while simultane- ously applying an alternating electric potential to the induction heaters to heat the pipe to a suitable application temperature for a coating material, the coating material being applied to the thus-heated pipe through the dispenser while continuing to rotate the assembly, water being passed through the copper coils to keep them cool during the heating of the pipe.
