Abstract
Provided are a method and a device for producing a frame structure, in which influences of both a thermal distortion due to welding and a decrease in the accuracy of the frame member itself are eliminated and high geometrical accuracy is obtained. The method for producing a frame structure includes supporting both ends of a long frame member, temporarily fixing a connecting member to somewhere along a longitudinal direction of the frame member, and final-welding the connecting member to the frame member while keeping the frame member in an elastically deformed state by imposing a bending load on an intermediate portion along the longitudinal direction of the frame member.
