ABSTRACT:
A preventive method for thin-gage plate deformation in manufacturing flat plate welded structures, which are constructed by welding thin-gage plates and frames and are used for side-plates, etc. in rolling stocks. The said method comprises preheating the whole thin-gage plate in a heating box for thermal expansion, and welding the thin-gage plate and the frame as the plate is expanded.
