It is shown that to increase the productivity of robotic fabrication of fragments of steel truss RHS (Rectangular Hollow Section) structures it is advisable to make workpieces by precision laser cutting with subsequent assembly of fragments by point tack and consumable-arc seam welding with current-carrying (hot) filler wire. Laser cutting with radiation power of ~1.0 kW and compressed air blowing at the pressure of 1.5 MPa allows obtaining ready for further welding elements of RHS structures with the accuracy of 0…0.1 mm. It is established that in the case of application of consumable-arc welding with hot filler wire, the speed increases by ~1.5 times compared to conventional consumable-arc welding 13 Ref., 6 Fig.
Keywords: laser cutting, welding, consumable electrode arc, current-carrying filler wire, angle joints, carbon steel, structures
