A normalizer for linear welds in continuous pipes, to travel along the side a pipeline during operation. The normalizer comprises an induction heater supported on a mounting assembly. A power source is provided for the induction heater and an electrical control means controls the power from the power source to the induction heater. A mechanical means continuously controls the elevation and lateral placement of the mounting assembly and induction heater with respect to those of the pipe. A mechanical control means enables continuous control of the lateral placement of the mounting assembly and induction heater with respect to the pipe weld to be normalized and ensures proper placement of the induction heater over that weld. A spacer means 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 means for moveably transporting these elements along the length of pipe to be normalized. The carriage means has appropriate drive and steering means for the carriage means.
