“…Prior to actual experimentation, the sample was machined using the wire cut electric discharge machining (EDM) at the butt surface to avoid sharp edges and foreign particles. CO2 Laser beam welding [2,21,22] processes for the current experimentation is displayed in Figure 1. The controllable factors employed for joining dissimilar materials of SS321 and Hastelloy C-276 are given in Table 2, which refers to experimental input as per the L4 orthogonal array [23] with the matrix; each parameter (Laser power, welding speed and shielding gas) taken at two levels.…”

“…In multipass welding, the high heat input will affect the lattice spacing and affect the weld's mechanical and microstructural and results low joint efficiency. The use of lasers for joining and cutting metals is rising in industrial applications and other engineering components because of its concentrated high-power density at a localized area, resulting in a very narrow heat-affected zone [1,2]. By using the laser beam welding process, increased productivity can be achieved with improved structural and mechanical properties.…”

The laser beam welding process is a promising technology because of its reliability and ability to automate the process easily. This study aims to analyze distortion for dissimilar laser weld joints. Hastelloy C276 and SS321 plates are joined by using the CO2 Laser beam welding. Welding current, welding speed and shielding gas flow are chosen as process parameters for preparing butt joints. Each of the factors has two levels to control the parameters of the output. Experimentation was conducted with four trails by using an L4 orthogonal array. The quality of the welds and bead geometry are verified through macrostructure examination. The Vernier height gauge was used for the measurement of distortion in the weldments. Lower the better-quality characteristic is chosen for the response. ANOVA studies identified laser power at 81%, the weld speed at 16% parameters is a contribution with a statistical of about 95%. Full penetration was observed for all the experimental trails.

“…In terms of dissimilar welding, the pulsed weld effect on a combination of Hastelloy C-276 and Monel 400 Ni-Co alloys (typically used for nuclear applications) developed a complete penetration joint (Figure 16J) [113]. The FZ was composed of columnar dendritic grains near the Hastelloy interface and fine dendritic grains in the Monel interface, with austenitic phase γ, chromium-rich carbide (Cr 23 C 6 ), and nickel-rich oxide (NiCuO 3 and NiFe 3 O 4 ) precipitates.…”

Joining metallic alloys can be an intricate task, being necessary to take into account the material characteristics and the application in order to select the appropriate welding process. Among the variety of welding methods, pulsed laser technology is being successfully used in the industrial sector due to its beneficial aspects, for which most of them are related to the energy involved. Since the laser beam is focused in a concentrated area, a narrow and precise weld bead is created, with a reduced heat affected zone. This characteristic stands out for thinner material applications. As a non-contact process, the technique delivers flexibility and precision with high joining quality. In this sense, the present review addresses the most representative investigations developed in this welding process. A summary of these technological achievements in metallic metals, including steel, titanium, aluminium, and superalloys, is reported. Special attention is paid to the microstructural formation in the weld zone. Particular emphasis is given to the mechanical behaviour of the joints reported in terms of microhardness and strength performance. The main purpose of this work was to provide an overview of the results obtained with pulsed laser welding technology in diverse materials, including similar and dissimilar joints. In addition, outlook and remarks are addressed regarding the process characteristics and the state of knowledge.
