The paper deals with a study and comparison between welding with several wires in different shielding atmospheres and single-wire welding. The first part treats the equipment for multiple-wire electrode welding and a comparison between single-wire welding and multiple-wire welding. The second part deals with the melting rate as a basis for determining the productivity of welding processes, and the third one with the energy efficiency as a criterion of cost-effectiveness of welding. The fourth part states some results obtained regarding strength of submerged arc welded joints produced with a single wire electrode and those produced with a multiple-wire electrode. Finally some conclusions are drawn.
