Considering the operational differences between the process tubular electrode and GMAW process, two welding processes competitive in terms of quality and productivity, was evaluated a methodology to the productive capacity of each process under different aspects. It was realized a comparative study of melting rate, deposition rate and efficiency deposition, concluding with an analysis of the productive capacity of each wire in question. Welds beads were evaluated using the wire E71T-1 and ER70S6, under shielding gas 100% CO2 and Ar +25% CO2 at different current levels, using groove plates. For enable a good comparison with the practical reality of each consumable, were tried to work with every combination wire / shielding gas and appropriate conditions of contact-tip-to-workpiece distance and arc voltage (for the current range studied, solid wire was used in short-circuit, using a smaller DBCP). The volume of the weld beads per meter was made the same for each level of current.). In general, the tubular wire used showed a higher deposition rate than solid wire, but with a higher consumption of material to form the same weld bead. An economic analysis showed that with the tubular wire is possible to perform a bead in less time (higher productivity), and the higher cost may be the result of the price of products on time.
