FIELD: laser processing equipment, welding technology. SUBSTANCE: made on surface of lower sheet are longitudinal grooves, which are filled before explosion with easily removable rods with wire spirals wound thereon. After explosion rods are removed. Mass of material is decreased due to cylindrical hollows and presence of wire spirals adds rigidity of the material and facilitates its further rolling. EFFECT: decreased mass of material, its improved rigidity and capability for subsequent rolling. 2 dwg
