“…When welding current reached 220 A, intergranular corrosion resistance remained better than that of the MIG AM surface layer, indicating that BC-TWIAW can efficiently solve the intergranular corrosion problem. Results of the previous study [22,28] showed that there are more δ-ferrite phases diffusely distributed in BC-TWIAW deposition layer. These δ-ferrite phases not only distribute inside the γ-austenite grains, but also distribute on the grain boundaries of the γ-austenite phases.…”

“…The base material has no active spots, and arc heat is chiefly applied to melt twin wires. Thus, under the same welding current, Wu et al [22] proved that it could achieve a better deposition efficiency than MIG. Meanwhile, arc heat acting on the substrate is low, which helps abate heat input on the workpiece and suppresses thermal deformation.…”

This study investigates the application of bypass coupling twin-wire indirect arc welding (BC-TWIAW) in arc additive manufacturing of 18-8 stainless steel. It is found that the droplet transfer changed from short circuit mode to stable spray mode with the welding current rising. Droplet transfer was the most stable when welding current was 200 A. Compared with the conventional MIG welding arc additive manufacturing, the efficiency of BC-TWIAW additive manufacturing can be increased by more than 30%. Electrochemical tests show that the BC-TWIAW overlay has a lower reactivation rate, higher charge transfer resistance, and lower carrier concentration, indicating that the overlay has better resistance to intergranular corrosion and pitting corrosion.

“…In contrast, at low energy input (0.65 kJ/mm), the dilution percentage decreases to 14.37%. Figure 2a,b shows how a higher heat input allows for non-uniform dilution throughout the coating as the cooling rate increases [53,54]. These results help understand how the process parameters used influence coating thickness and provide a base for effectively tuning these parameters.…”

Within the drilling, petrochemical, construction, and related industries, coatings are used to recover components that failed during service or to prevent potential failures. Due to high stresses, such as wear and corrosion, which the materials are subjected to, industries require the application of coating between dissimilar materials, such as carbon steels and stainless steels, through arc welding processes. In this work, an austenitic stainless steel (ER308) coating was applied to an H13 tool steel substrate using the gas metal arc welding (GMAW) robotic process. The heat input during the process was calculated to establish a relationship between the geometry obtained in the coating and its dilution percentage. Furthermore, the evolution of the microstructure of the coating, interface, and substrate was evaluated using XRD and SEM techniques. Notably, the presence of martensite at the interface was observed. The mechanical behavior of the welded assembly was analyzed through Vickers microhardness, and a pin-on-disk wear test was employed to assess its wear resistance. It was found that the dilution percentage is around 18% at high heat input (0.813 kJ/mm) but decreases to about 14% with reduced heat input. Microhardness tests revealed that at the interface, the maximum value is reached at about 625 HV due to the presence of quenched martensite. Moreover, increasing the heat input favors wear resistance.

“…For example, Wang et al [8] achieved the process of depositing CuSi3 Cu alloy onto 30CrMnSi steel plate with consumable and nonconsumable electrodes indirect arc welding (CNC-IAW) technology. Wu et al [9,10] prepared the stain steel surfacing layer with twin-wire indirect arc welding (TWIAW) and investigated its corrosion resistance behavior. The result clarified that compared with MIG surfacing layer, that of TWIAW obtained a better intergranular corrosion resistance due to the faster cooling speed during TWIAW restraining Cr23C6 precipitation.…”

Continuous contact transfer mode in bypass coupling triple-wire indirect arc welding (BCTW-GIA) is proposed to pursue an optional way to ensure the high deposition rate and obtain stable depositing process. The arc behaviors, droplet transfer and process stability with different distance between the tips (d1) of the main wire and side wires and the feeding speed of main wire (FSM) were studied. With the increase d1 and FSM, the droplet transfer mode of main wire varied from explosive transfer to short-circuit transfer to bridge transfer. When the d1 was greater than 4 mm, the continuous contact transfer bypass coupling triple-wire indirect arc welding can be realized and the welding process stability was improved. With the d1 adjusted from 0 mm to 6 mm, the standard deviation of the current dropped from 123.8 to 53.8 and its variation coefficient from 117.33% to 39.24% at FSM= 1 m/min. The weld penetration and weld width reduced with the FSM increasing, while the weld reinforcement gradually increased.
