“…At present, the industries are aiming to minimize the cost together weight with a compromise between of high performance and safety. The welding process was achieved by an enormous electric current flow through touching the sheet metals to heat up and compose a molten nugget [3][4][5] . Regularly, the steel body of the vehicle usually contains about 5,000 spot welds to join sheets of various thickness, and the spot welds quality dramatically influence the reliability and safety of an automotive structure 6,7 .…”

The purpose of this research is to analyze the mechanical properties and corrosion resistance of spot welding of stainless steels AISI 316L using the process of resistance spot welding varying welding parameters with three level for each of welding parameter; welding current (A.), electrode Pressure (bar), squeeze time (s.), and welding time (s.). The welding current was (4500, 5500 and 6500) A, the electrode Pressure was (20, 30 and 40) bar, the squeeze time was (0.6, 0.8 and 1) Sec., and the welding time was (0.3, 0.6 and 0.9) Sec. The specimens were inspected by a tensile-shear test, corrosion test and the inspection of scanning electron microscope (SEM). The technique of design of the experiments (DOE) was utilized to examine the influence of the welding process parameters on the joint tensile-shear force. The results were analyzed by the DOE method to determine the optimum tensile-shear force, where can be obtained by utilizing the welding parameters by welding current 5500A, electrode pressure of 30 bar, squeeze time 0.8s., and welding time of 0.3s. The examination of SEM indicated that the increment of welding current and electrode pressure leads to increment pitting and corrosion rate.

“…Near contact between the polymer and metal was acquired by mechanical interlocking, chemical bonding and physical happening at the interface. By using a hot press process to join a hybrid form of aluminium alloy AA6061-T6 together with polyamide, the aluminium sample was pre-holed with a 5 mm diameter of two holes [15,16].…”

A hot press process was used as a technique to pound a polyamide type of polymer of a thickness (2mm) to stainless steel AISI 316L of the thickness (1mm). A hybrid joint of dissimilar material was accomplished by a hot press bonding process. During the joining process, three different parameters of process were used: processing temperature of 175, 170 and 165°C, processing pressure of 3, 6 and 9 bar and time of 1.5, 3 and 4.5 min. The surface of stainless steel was prepared and treated by a mechanical treatment (surface grinding) to improve the wettability to increase the shear strength. A shear tensile, scanning electron microscope (SEM) and energy dispersive spectrometry (EDS) tests were used to investigate and examine the joint (bounding) specimens. The Minitab program was used to analyze the effect of the parameters of the joining process on the joint properties. The maximum and minimum values of shear force are exhibited at a processing temperature of 165°C, applied pressure of 6 bars and processing time of 1.5 minutes; the minimum shear force was found to be 675 N, while the maximum shear force was 2182 N at a processing temperature of 175°C, applied pressure of 6 bars and processing time of 3 minutes. The tested joints failed by an interfacial shear and necking in the polymer side with a ductile fracture. The joining process occurred through a mechanical interlocking between the molten polymer and the treated surface of the steel specimen. The average thickness of the joining line for the tested specimens was 8µm.

“…Most importantly, the properties of additively manufactured components using 3D printing technique are affected by the filling factor, print and raster direction, and layer-to-layer thickness [30]. There is a great deal of studies [31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47][48][49] analyzing the effect of various variables on mechanical characteristics, especially tensile characteristics. Camposeco-Negrete [50] analysed the impact of layer print size, infill shape, raster direction of 3D-printed parts using Taguchi and ANOVA methods.…”

One of the most cost-effective additive manufacturing (AM)/3D printing techniques for complicated geometry components is fused deposition modeling (FDM). FDM is a method of fabricating parts by depositing successive layers of material in accordance with computer-aided design file. The properties of the finished products manufactured with FDM are sensitive to the process parameters used. Most FDM items still lack adequate mechanical characteristics when compared to those produced using conventional methods. This investigation seeks to address this knowledge gap by fabricating tensile specimens from Polyethylene Terephthalate Glycol (PETG) filament in a variety of geometries, including grids, octets, triangles, and hexagons. To verify this claim, samples studied was printed with varying infill percentages (25, 50, 75, and 100) % to see how this impacted the mechanical characteristics such as tensile strength and fractured strain. Although the best results for tensile stress and hardness were achieved with a 100% infill percentage in all four printing situations, the triangles orientation consistently produced the best results.
