<p>A normalizer for linear welds in continuous pipes, to travel along the side of a pipeline during operation. The normalizer comprises an induction heater supported on a mounting assembly. A controlled power source is provided for the induction heater. The elevation and lateral placement of the mounting assembly and induction heater as well as its lateral placement are continuously controlled with respect to the pipe to ensure proper placement of the induction heater over the weld to be normalized. A spacer permits adjustable spacing of the induction heater a predetermined distance from the pipe weld to be normalized, to provide a predetermined air gap between the induction heater and that weld. These elements of the normalizer are mounted on a carriage for moveably transporting these elements along the length of pipe to be normalized.</p> |
