“…For low carbon steel, the inhibitory effect of inorganic glass composed of (50% K 2 O, 25% P 2 O 5 and 25% CaO) in 1 M HCl shows that the optical structural analysis provides a good protection for the surface 1 . The experimental results show that when the forging pressure increases, the hardness of the welding interface will increase when the tensile strength decreases 9 . The electrochemical and microstructural behaviours of "A106—Gr.B" and 316L welded pipes with nickel based alloys were studied.…”

The main purpose of this study is to elaborate anticorrosive coatings for the welded steel 316L, since this later is widely used in industrial field. Hence, within this work we have studied the electrochemical behaviour of different zones of the welded steel 316 in 1 M HCl media. The macrography study of the welded steel has revealed the different areas with a good contrast. We have stated three different zones, namely; melted zone (MZ), heat affected zone (HAZ) and base metal zone (BM). Impedance studies on welded steel 316L were conducted in 1 M HCl solution, coating of Epoxy/Alumina composite was applied on different zones, in order to reveal the anti-corrosion efficiency in each zone. Scanning electron microscopy (SEM) analysis was undertaken in order to check how far the used coating in such aggressive media protects the studied zones and these findings were assessed by water contact angle measurements. The choice of this coating is based on the cost and the safety. We concluded that the Epoxy/Alumina composite has a good protecting effect regarding welded steel in aggressive media.

“…For example, a discontinuous layer that formed at the joint interface during the friction welding between the pure Al./Fe metals caused the failure almost at their joints when the load applied [10]. Similarly, Gawhar and Sherko [11] joined the SS316L steel to AISI1045 steel and found the failure nearby the thermo-mechanically affected zone (TMAZ), also the author informed that the forge pressure is responsible to increase the hardness. The dissimilar joints are made successful only if there is mutual solubility of the two metals.…”

This work describes the effect of newly introduced faying surfaces on the microstructure and the mechanical properties of dissimilar weld joints of AA6063 and AISI304L alloys that fabricated through the rotary friction welding process (RFW). The experiments were done as six different experimental methods ('A' to 'F') at 1300 rpm rotation, 18 MPa friction pressure (FP), 24 MPa upset pressure (UP) and 5 sec friction time (FT) with the faying surfaces of hemispherical bowl and thread of 1 mm pitch on the weld specimens. The fabricated joints and the weld zones were characterized by macro and micro-study, Energy Dispersive X-ray Spectroscopy (EDS) spectrums, tensile properties, Vickers microhardness, impact toughness and fractography. The results showed that these faying surface modi cations strengthen the bonding between the weld specimens and in uences the performance of the joints. The hemispherical bowl showed better results than the threaded surfaces. Axial shortenings were within the acceptable limit in the range of 20-27 mm. Macro and microstructural studies showed the defect-free weld joints and the strong bonding between AA6063 and AISI304L alloys. The hemispherical faying surface on AISI304L alloy formed a U-shaped weld interface (WI) in the dissimilar joints. EDS proved the formation of the Fe-Al intermetallic and the element 'O' at weld zone. The joint e ciency for all the methods was around ≥ 100%. Maximum tensile strength was recorded as 238 MPa for method 'F'. The threaded surface showed good hardness property nearby WI and method 'A' yielded maximum impact toughness for the joint.

“…Studies on microstructures and mechanical structures obtained by combining two different materials with arc welding are also available in the literature [21]. In addition, the investigation of both microstructure and mechanical properties of structures obtained by combining different materials with friction welding is another study subject [22][23][24][25][26][27][28][29][30][31][32][33]. In [34,35], microstructure properties of materials of the same type are studied.…”

In recent years, with the development of welding methods, using these methods in manufacturing industry and in advanced engineering has become more popular. In this study, mechanical properties of rods obtained by friction welding and electric arc welding are compared. Hence, three specimens with different material properties are manufactured, two of which are welded by friction welding and one of which is welded by electric arc welding. These three specimens are adapted to the ASTM E8-04 standard with the help of a universal lathe. Moreover, the tensile stress values and the elasticity modulus of all these specimens are obtained as a result of tensile tests. Accordingly, the effects of the type of welding and material properties used in manufacturing on the mechanical behavior of the specimens are examined. In addition, specimens taken from the cracked surfaces of the pieces broken from the specimens as a result of the tensile test are examined with SEM (scanning electron microscopy). These examinations reveal the microstructure of the specimens. The elemental distribution data obtained as a result of examinations with SEM and the mechanical property data obtained as a result of tensile tests support each other. Furthermore, effects of a heat affected zone (HAZ) on the mechanical properties of the rod are investigated as a functionally graded material.
