    • This aims to provide a method for heating the welded portion of a steel pipe material so as to melt and pressure-weld the welded portion, and an apparatus for the method. When the moving steel pipe material is continuously induction-heated and welded as a heating object, the temperature of the welded portion, the shape of the welded steel and the welding frequency fluctuation are controlled highly precisely and highly efficiently irrespective of the shape of the heated portion of the heating object or the material of the heating object. The welded portion heating method comprises a first imaging step of detecting the spontaneous light of the welded portion by first imaging means (3) arranged to confront the welded portion of the end face of the steel pipe material, thereby to output a brightness image, a welded portion temperature-distribution computing step of treating the image on the basis of the brightness image, thereby to compute the thickness-direction temperature distribution of the welded portion by a radiant-light temperature measurement, a heating control step of deciding the frequency of an AC electric current on the basis of the thickness-direction temperature distribution by using an evaluation reference of the relation between the frequency of a preset AC electric current and a thickness-direction temperature distribution, and a step of feeding the AC electric current of the frequency decided at the heating control step, to the steel pipe material (10) by using an AC power source (1) of a variable frequency.
