FIELD: manufacture of T-members of orthotropic plates used in machine engineering and in building.
SUBSTANCE: method comprises steps of placing on supporting bed of assembling stand board sheet and securing it along contour; with use of attachments mounting on said sheet in parallel to its lengthwise edges rigidity ribs; fixing one ends of rigidity ribs and mounting second ends of rigidity ribs with possibility of axial motion; applying to free ends of rigidity ribs tension effort whose stress is no more than limit yield of material of rigidity ribs; performing continuous-seam welding at side of fixed end of rigidity rib; releasing welded orthotropic plate from supporting bed of assembling stand.
EFFECT: simplified process for making orthotropic plate due to elimination of procedures for preliminary tack welding of ribs and for heat straightening of welded plate.
