“…MAG welding is widely used in the petrochemical, shipbuilding, engineering machinery, and automotive industries due to its high welding efficiency, good welding quality, stable arc, low spatter, strong penetration, and ease of automation [1]. The gathering and processing of the product manufacturing process and quality information has grown in importance as a component of information technology in the welding manufacturing business because of the rise in demand for high-quality, efficient, and refined welded goods [2].…”

In this study, a platform for a welding experiment, used to collect input and output electrical signals, was constructed, and the algorithm for the input pulsating energy interpolation line (IPEI) was given. Experiments with MAG surface straight line welding were conducted at various voltages. Analysis of the IPEI in relation to the welding current was performed while combining real-world welding occurrences with high-speed camera images of droplet transfer. It was established that the IPEI can be employed as a characteristic parameter to assess the stability of the short-circuiting transfer process in MAG welding. The three criteria for assessing the stability were the spectrum, approximation entropy, and coefficient of variation. A comparative analysis was conducted on each of these approaches. It was determined that the most effective technique is approximation entropy. The approximation entropy of the welding current and IPEI are also highly consistent, with a correlation coefficient as high as 0.9889.

“…Laser cladding had a lower dilution and lower specific wear rate and they recommend laser cladding for the narrow HAZ with high hardness. Kumaran et al [14] mentioned that the gas metal arc welding produced cracks in the welding of aluminium, and used the CMT process to overcome such crack problems. The authors made butt joints for the comparative study on AA7475 alloy using normal and pulsed CMT processes.…”

In this work, Cladding was done on SS316L alloy through the CMT process using Stellite-6 filler wire. 31 experiments were done at different welding conditions as per CCD matrix. The cladding specimens were characterized by macro and micro-study, Vickers microhardness evaluation and corrosion resistance analysis. An optical microscope, SEM-EDAX, and XRD were used to predict the structural characterizations, presence and the distributions of the elements. Based on the study higher voltage & welding speed showed appreciable hardness at the interface & cladding regions. The thickness of the interface was noted at a maximum of 190 μm. The EDS spectra showed that Fe, Cr and Co were the major elements in the clad and interface regions. The Co-rich phase and the low content of element O are found in the low corroded regions on the specimen. The maximum hardness observed at cladding and interface were 378 Hv and 270 Hv respectively.
