“…In addition, the cross-section shows that there are no defects such as porosity, incomplete fusion, crack, etc [28]. Table.4 gives the total wire melting rate, base metal penetration depth, and the weld bead dilution rate [29] of the above weld beads. From the table it is seen that with the same current, TW-GIA welding more than doubles the wire melting rate.…”

This paper proposes a novel triple-wire gas indirect arc welding process. The welding system consists of two power sources and three wires. The effects of the power source mode and the wire configuration on arc stability and behavior are studied. The metal transfer is analyzed and bead-on-plate welding is employed. Results show that two direct current power sources cannot produce a stable process, but the combination of a direct current with a pulsed direct current can produce a stable process. The reason is that the pulsed direct current can boost and stabilize the metal transfer. For the wire configuration, a smaller contact angle between the main wire and the side wire is more desirable.Compared with the traditional gas metal arc welding, this novel process has the advantages of high wire melting rate, low penetration depth, and low dilution rate. Compared with twin-wire gas indirect arc welding, it provides a broader range of applicable currents with sufficient heat input.

“…The dilution in PTAW process usually varies between 5% and 20% for high deposition rate and it can be reduced up to zero percent at low deposition rate [13,14]. It has also been observed that the dilution is more sensitive to arc current and scanning speed than to powder feed rate [15].…”

Experiments are conducted to deposit SS304 L powders on SS316 plates by plasma transfer arc welding process with varying four input process parameters, namely scanning speed, powder feed rate, stand-off distance, and current. The effects of these four input process parameters on deposition geometry, dilution, and bead continuity are investigated in this study. Attempts have been made to explain the experimental results with only two compound parameters, ''energy deposition per length'' and ''powder deposition per length'' instead of four independent input process parameters. It is observed that the variation of dilution is very little when the scanning speed increases from 100 to 600 mm/min and other process parameters remain constant. When the powder feed rate increases and other parameters remain constant, initially the dilution decreases rapidly and attains a minimum value which do not change further with increase in powder feed rate. It is also observed that the dilution remains almost constant around 6-9% as the stand-off distance changes from 7 to 11 mm and other process parameters remain constant. The formation of nonuniform bead is found to be due to insufficient energy deposition per length per mass of supplied powder.

“…Lakshminarayanan et al [10] and Barroi et al [11] have described that for high deposition rate, the variation of dilutions are in between 5 to 20% and for low deposition rate, the dilution may be reduce up to zero percent. Robert Jayachandran et al [12] have shown that the effects of scanning speed and current on dilution are more compare to powder feed rate. Xibao et al, [13] Sudha et al [14] and Kumar et al [15] have discussed the effects process parameters on micro-structural analysis of the deposited bead in the PTAW process.…”

The quality and geometry of deposited bead depend on their input process parameters and their interaction effects in fusion welding process. Minimum dilution and maximum bead size are the most desirable property in material processing applications. The effects of process parameters on dilution and bead geometry have been analysed during material deposition by Plasma Transferred Arc Welding (PTAW) process using the response surface method. The experimental data are used for modelling using three level factorial techniques. The mathematical models have been developed for bead height, width and dilution. The accuracy of the models has been checked using the analysis of variance. The effects of process parameters on bead geometry and dilution have been investigated.
