METHOD AND TRAIN OF MANUFACTURING OF FLAT RIB STEELWORKS BY METHOD OF HIGH FREQUENCY WELDING Russian patent published in 2016 - IPC B23K13/00 B23K37/04 

FIELD: metallurgy.

SUBSTANCE: surface of blank and ribs are fit with creation of V-shape slit with top in point of convergence. Welded surfaces are heated by HF currents till melting in the point of convergence, and they are swaged to create welded joint. To the welding place flat plate blank and pre-bent ribs are supplied. The ribs are welded one-by-one is set sequence with specified spacing. Straightening of the welded ribs is performed just after welding. Device of ribs supply contains cartridge in form of space frame to arrange ribs with device of single-piece feeding to the place of welding with plate blank. Welding device has possibility of movement in horizontal plane. The train is equipped with devices to return the plate blank after each rib welding to the initial position.

EFFECT: manufacturing of flat rib steelworks with large dimensions with thick elements and with variable ribs spacing.
