“…The problems of arc interruption and hump were also studied by Hua’s research group [ 19 , 20 , 21 , 22 ]. Fang et al [ 23 ] proposed a triple-wire indirect GMAW process, which consists of one main wire, two side wires and two power sources. In the system, the workpiece never needs to be plugged in, while the main wire and the two wires were connected with the negative pole and the positive pole of the two power sources, respectively.…”

Multi-wire welding has received much attention in the machinery industry due to its high efficiency. The aim of this study was to investigate a novel pulse gas metal arc welding (GMAW) that has circular triple-wire electrodes. The effect of the pulse phage angle on arc stability was particularly studied. Research showed that for typical phase angles the arc stability from low to high is 180°, 0°, and 120°, and the arcs are very stable at 120°. The triple-wire welding was used to weld a 9 mm thick Q960E steel, which is typically used for the arm of construction machinery. When the welding heat input was controlled at 1.26–1.56 kJ/mm, the weld zone was dominated by acicular ferrite, and the coarse-grained zone of the heat-affected zone was a mixed structure of lath martensite and lath bainite. The tensile strength of the welded joint reached 85% of the base metal and the impact toughness was above 62 J, which can meet the requirements of construction machinery. This indicates that the triple-wire welding has great potential to achieve efficient and high-quality welding for the construction machinery.

“…This situation is changed by the appearance of the cable-type welding wire (CWW) containing different composition metallic wires [35][36][37]. The research on CWWs has become an interesting research hotspot in new welding and additive manufacturing [38][39][40][41][42], but the research on the preparation of HEA/MEA coatings via CWW-GMAW has not been effectively carried out. The CWW makes it easy to prepare HEA/MEA coatings via GMAW.…”

The Mo–Fe–Ti–Ni–Cu medium-entropy alloy (MEA) coating was prepared based on a GMAW – Robotic Integrated Cladding System with the MoFe3TiNiCu cable-type welding wire (CWW) containing 1-Mo, 3-Fe, 1-Ti, 1-Ni and 1-Cu pure metallic wires. The produced MEA coating is composed of FCC major phase and BCC minor phase. The hardness of the produced MEA coating is between 400 HV and 450 HV, while the substrate is about 190 HV. The produced MEA coating can greatly improve the wear resistance of the substrate, and its friction coefficient is 0.4, which is far lower than that of the substrate (0.65).
