“…The mechanical properties are improved by using the acceptable current range and suitable conditions to increase the spot weld size [24]. In the present study, Minitab was utilised to analyse the effects of the technique parameters on the joint properties, considering that the surface treatment can significantly affect the shear strength [25,26]. RSW was conducted to weld alloy materials according to the "AWS/ANSI C1.1M/C1.1:2012 standard", while accounting for the "welding current, pulses, squeezing time, and welding time" [27].…”

Resistance spot welding (RSW) is an important fusion welding process used in many applications, including storage tanks, pipes, and medical tools. For this, should be improved the joints and developing the process parameters and through this research will be discussed the results and concept development. Herein, 1 mm-thick AISI 316 austenitic stainless steel was welded by RSW, and the effect of the welding process parameters, such as “welding current, pulses, squeeze time, and welding time”, on the mechanical properties, nugget diameter (ND), and microstructure of AISI 316 were investigated. As a result, there was a direct relationship between shear-tensile force and ND. The maximum shear-tensile force (12.5 kN) was obtained using 7500 A, 3 pulses, 1.8 s squeeze time, and 1 s welding time. The ND was maximized using 7500 A, 3 pulses, 1.6 s squeeze time, and 0.8 s welding time. The DOE analysis gives an indication about the relation between the parameters and ND on the hand and the parameters and shear strength on the other hand. The microstructure was investigated by optical microscopy, revealing the presence of martensitic, widmanstatten austenite, and ferrite structures.

“…This type of joining is called hybrid joint, and the engineering applications for it biological and medical industry, automobile, and aerospace are constructed from hybrid components of dissimilar lightweight materials, such as copper, stainless steel, aluminium, or magnesium alloys and polyamide, polyvinyl chloride, polyethene and fibre reinforced polymers [3]. Hybrid joints are given combines the ductility and strength of metals with the resistance of physicochemical and polymers' high specific stiffness in these parts, which are hybrid welded [4]. Many processes of hybrid joints for bonding metal to a polymer, such as the hot press bonding method [5].…”

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.

“…The treatment of the surface of the aluminium should be done to increase the wettability of it. Hybrid joining of materials is very important because it provides many properties which aren't found in one material [1]. Hybrid joining is necessary to produce a lightweight of dissimilar materials having high strength, corrosion resistance, toughness and conductivity [2].…”

The friction spot welding process is used to join the hybrid joint of aluminium to polymer. AA 1050 Aluminum alloy and polyethylene polymer (type of plastic) were used for joining. Aluminium surface treatment was done to increase the wettability of it. The surface treatment was done by electrochemical treatment. Two parameters of the joining process were used: (1, 1.5 and 2) min. (920, 1340 and 1500) rpm for time and rotational speed, respectively. Many tests for the joint are done: shear test and Scanning electron microscopy (SEM). Using the Minitab program, the effect of the parameters on the joint was analysed. The maximum value of the shear force was (1587 N) at 1.5 min. time and 1340 rpm rotational speed. The minimum shear force was (589 N) at 1 min. time and 920 rpm rotational speed. The joints which were tested failed by an interfacial shear with a ductile fracture of the polymer side. The process of joining mechanism occurred through a mechanical interlocking between the molten polymer and the surface of the AA 1050 aluminium specimen, cohesive and adhesive. The average thickness for the joint of the tested specimens was 4µm.
