“…Irrespective of the wire diameters, the relationships between the welding current and the deposition rate were almost the same, but the maximum deposition without formation of puckered bead was dependent on the wire diameter. The tandem-wire process achieved the highest deposition rate although the cross-sectional area of the 3.2-mm wires was two times the sum of the cross-sectional area 7 a wire with a large diameter could suppress the formation of puckered bead to a certain extent by reducing the arc pressure, but the multiple-wire welding was more effective than the single-wire welding using a large-diameter wire.…”

“…This is because of the formation of puckered bead, which is inevitable at high current using a thin welding wire. 3,[5][6][7][8] During this time, because of the limitations of control technology for welding power sources, the conventional welding equipment with a continuous wave (CW) output power was used along with a special control technology to improve the arc stabilization in CW mode. 9 In recent years, the rapid advances in digital inverter-based welding power sources have allowed the realization of pulse GMA welding, which achieves stable metal transfer even at low welding currents and thus reduces the heat input to the base material.…”

The recent rapid advances in digital inverter-based welding power sources have allowed the realization of pulse gas metal arc welding, which can achieve stable metal transfer even at low welding current and thus reduce heat input to the base material. Moreover, a tandem-wire process using two electrodes can dramatically increase welding productivity. In such a process, two pulse power sources are synchronized and the interference between the adjacent welding arcs is minimized. In this study, high deposition rate pulse welding for Al 5083 alloy was implemented by using Al 5183 wire of three different diameters-1.6, 2.4, and 3.2 mm. Unlike the single-wire process, tandem-wire welding was only implemented using 1.6-mm-diameter wire. The bead shape, deposition rate, process windows, and stability were evaluated for each process. The results indicate that large wire diameters and the tandem process are preferable for high deposition rates, and the penetration depth is dependent on the welding current and speed. The tandem process achieves a remarkably high deposition rate, but spatter generation at high-current levels needs to be addressed.

“…As high requirements of deposition and production rates in reality, single-wire welding cannot sufficiently satisfy the practical demands, the existing technology has been improved in various aspects. The multiplewire welding technology is one of such improvements which have been proposed to increase the deposition rate [3], so as to improve the productivity during the applications.…”

Recently, double-wire gas metal arc welding (GMAW) process is more and more prevalently employed in industrial applications and attracted many academic researches. This paper reviewed the recent trends of researches and applications of this process. Three main aspects were included in this paper. The first was the operational process analysis of the process, and the reviewing work was divided into two catalogues: twin-wire GMAW process and tandem GMAW process, which were two main energy delivery and control formations of the process. This part focused on some negative phenomena, such as arc interruption, during the welding process and their effects on the products quality and process stability. Some works about using different current waveforms combinations and their effects on the welding process were discussed. Also, the works of numerical simulation for this process were mentioned in this part. The second part was about process stability monitoring, and corresponding works focused on establishing quantitative process stability estimation model. The last was the improvement of process control method, and the works mainly focused on the adjustment and modulation of the current waveforms, in order to eliminate negative phenomena, improve the process stability and obtain the products with high quality. Finally, some suggestions about future works were presented. This paper can provide references and enlightens for current academic researches or actual industrial applications in the double-wire GMAW process relative areas.INDEX TERMS Double-wire GMAW process, arc interruption, process stability, current waveform.

“…However, because submerged arc welding employs granular materials as shield, it can only be applied in flat position of welding. To overcome this limitation, double-wire metal inert-gas (MIG) arc welding was then proposed, and increasingly employed in both of academic and practical industrial areas [2,3].…”

Abstract:To improve the energy efficiency and quality of the welding seam during the double-wire metal inert-gas (MIG) arc welding production, a new multi-frequency waveform control method was proposed in this paper. In this method, a multi-frequency modulation was added to the waveform in the peak stage of trailing wire current, under the situation that the two wires current waveforms had the same frequencies but inverse phases. This new action can benefit the stability of welding process and improve the quality of welding seam. Actual experiments were conducted to validate the proposed method. Orthogonal experiments and corresponding mathematical analyses were also employed to seek an optimal parameters combination. Finally, an optimal combination was confirmed and a welding seam with satisfactory quality was obtained, which showed that the proposed control method and corresponding analyses can well serve the double-wire MIG arc welding, and then benefit the actual production in the future.
