“…Test runs were first conducted to establish the parameters ranges to be used. It is widely known that welding Current is the most important welding factor in welding procedures because it affects its Currentdensity and, as a result, the melt filler and the base material [19][20][21][22][23]. Three sets of arc welding parameters were selected.…”

Welding is a type of manufacturing method that offers greater advantages than riveting for combining metals or sheets. By adjusting the welding process parameters to predict welding strength, a higher quality of joint can be achieved. In this study, the weld processing parameters welding current (WC), electrode angle (EA), and root gap (RG) were taken into account. We performed destructive testing, such as tensile and hardness tests, to evaluate the metal piece's weld strength after it had been joined. Stainless steels and carbon steels, two unrelated materials, were used in this project. The Taguchi method was used to carry out joint processes in arc welding (AW), and nine samples were produced by altering the input parameters. Steel alloy 308L has been used as the electrode for forming connections.

“…Fig( 5): (a) single V butt, and (b) double V butt joints [11] Patil. U.S., and et al [12] investigated the effects of welding current, welding speed, electrode angle, and root gap on performance parameters, such as welding strength, metal deposition rate, and microstructure, when manually(shielded) metal arc welding stainless steel 304 to mild steel 1018. The primary concern when welding these two materials is carbon transfer, which can lead to carbide precipitation and failure of the welded connection.…”

The mechanical and metallurgical properties of dissimilar joining of 304 stainless steel (SS) and other alloys have been extensively studied in recent years. Stainless steel is a widely used material in various industries such as aerospace, chemical processing and transportation. The austenitic Chromium-Nickel stainless steel AISI 304 provides the best balance of corrosion resistance, endurance, and ductility. Due to the low carbon content, carbide precipitation during welding is less likely. The dissimilar welding of AISI 304 austenitic stainless steel using various welding techniques with various materials was thoroughly reviewed in the current paper. According to the review, the optimum material to use when intergranular corrosion is a concern is AISI 304 austenitic stainless steel. It is also among the best materials usually utilised in the production of components that cannot be heated.

“…The overlay-welding process is tedious and costly. The heat input is large and easily produces lots of welding slag and flying chips [5][6][7]. The thermal-spraying processes, such as HVOF, are mature technology and have benefits such as unrestricted workpiece size and high efficiency; however, due to the high process temperature, metallic elements are easy to oxidize, the coating porosity is relatively high, the microstructural uniformity is poor due to local corrosion, and thick deposits are difficult due to large residual stresses [8][9][10][11][12].…”

Aluminum target material is an important target material and is widely used in preparations of semiconductor films, integrated circuits, display circuits, protective films, decorative films, etc. In this study, pure aluminum coatings were deposited on stainless steel substrates by cold-spray technology as part of an overall project to produce large-size pure aluminum sputtering target materials. The results show that pure aluminum coatings exhibit high adhesive strength (~98 MPa), high deposition efficiency (~95%), and low porosity (~0.3%) on stainless steel substrates. The bonding mechanisms of pure aluminum coatings on stainless steel are a combination of metallurgical and mechanical interlocking. The evolutions of microstructure and mechanical properties of pure aluminum coatings under different heat treatments were also studied. With the increase of heat treatment temperature, it is found that cold-sprayed aluminum coatings become more homogenous in microstructure, the microhardness is reduced, and the adhesive strength seems to be slightly reduced. Overall, this study demonstrates significant advantages of cold-spray technology in depositing high-performance pure aluminum coatings on stainless steels.
