Abstract

PURPOSE:To safely and easily positioning by monitoring a position having a welding strain to be corrected by pressing using a laser beam and a telecamera. CONSTITUTION:Since a strain is generated when a vertical stiffener 11 is welded to a steel plate 10 of a box girder for web, the strain is corrected by an upper metallic die 16 and lower metallic die 17. The upper metallic die 16 is remote controlled to be positioned seeing an image in the telecamera 19 so as to the laser beam S from a laser beam oscillator 18 is projected toward the center part of the vertical stiffener 11 in its width direction. Since the lower metallic die 17 is always positioned at the center part of the upper metallic die 16, the lower metallic die 17 is elevated when the laser beam S is projected on the center of the vertical stiffener 11 in its width direction. Thus, the steel plate 10 is horizontally corrected and the welding strain is eliminated.
