PROBLEM TO BE SOLVED: To provide a post-heating apparatus for a welded part of steel sheets which is capable of properly post-heating the welded part, even in the occurrence on the steel sheets of various thermal deformations such as those in the direction of a weld seam and those orthogonal thereto, as the post-heating apparatus which performs the post-heating for the purpose of removing thermal effects of the welding after welding steel sheets to each other. SOLUTION: Even in the occurrence of various thermal deformations on steel sheets 1, for enabling smooth copying on the steel sheets 1 by a copying mechanism 4 connected with a burner 3, the apparatus is equipped with a total of four height following means 8 comprising two situated in the direction of the weld seam and two orthogonally thereto.
