Abstract
A welded shaped steel manufacturing device for weld-connecting a butt portion of a web member having an end butting perpendicularly against a flange member and thereafter correcting in shape the flange member subjected to thermal deformation caused by heat input during welding, the device includes: a corrective device including flange-member correcting rollers arranged for respective ends of the flange member, each configured to press each end on a web-member side of the flange member so as to correct the thermal deformation over a range of the flange member from each end thereof to the butt portion thereof against the web member, and web-member supporting rollers configured to support a web surface of the web member, wherein the flange-member correcting rollers arranged for the respective ends of the flange member apply independent pressures to the respective ends so as to correct the thermal deformation.
