METHOD FOR MAKING WELDED STRUCTURE WITH CURVILINEAR SURFACE Russian patent published in 2005 - IPC

FIELD: plastic working of metals.

SUBSTANCE: method for making welded structure with curvilinear surface having metallic sheets with parts welded to them comprises steps of shaping by successive or rotary application of local bending efforts during one or several transitions along surface area of structure; initially welding sheets one to other and welding parts arranged on sheet surface to said sheets; then performing formation of structure while by-passing welded joints and starting such motion of upper deforming member that it is to be in position being the nearest relative to welded parts in edges and ends of sheet; using pressure roller or punch as upper deforming member; using roller or double-support beam as lower deforming member; welding parts adjoined to curved surface of structure.

EFFECT: enhanced accuracy of preset curvilinear surfaces of structure, simplified manufacturing process due to reduced number of transitions.
