“…Stellite-6 is excellent in erosion, corrosion and wears properties [25,26]. A low carbon SS316L stainless steel is having good weldability and suitable for cladding applications, where the alphabetical letter 'L' in suffix is meant for low carbon content [27]. The cladding of stellite-6 filler wire of size ϕ1.2 diameter on the metal 316L sheet of size 420 mm length and 20 mm width was performed using the CMT method which is an advanced process of MIG/gas metal arc welding (GMAW).…”

Thisarticle discusses the welding parameters optimization to find the quality of stellite-6 cladding on AISI304L austenite alloy using a new optimization method called Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). The experiments(31 nos.) were carried out with the cold metal arc transfer welding method (CMT) based on the central composite design (CCD). The cladding material is the stellite-6 alloy which is appreciated for its corrosion and wear resistance. Four factors (welding current, voltage, welding speed and torch angle) and five levels were considered for the experiment and the optimization. It is necessary to find the optimized parameters for the industrial applications as a huge number of experiments are not recommended. The optimization results showed that the 2nd experiment had the 1st rank with high relative closeness and the 19th experiment was in the last rank. Higher current and low welding speed yielded good results and a low corrosion rate of 0.004582 mm/yr. Furthermore, the Micro-structural, Corrosion study and the SEM-EDS of the specimen produced by the 2nd experiment are discussed here. Cr and Co elements were most abundant, according to an EDS study, in the cladding region.

“…The maximum value of 15 kN was recorded for the methods 'E' and 'F', which means that a hard effort was given by the joints of methods 'E' and 'F' against the pulling load during the tensile test. It is mandatory to measure the weld joint e ciency to identify the effectiveness of the experimental welding methods and the quality of the joint considering the tensile strengths of both the joint and the soft base metal in the weld joint [25,26]. Here, the joint e ciency of the methods is calculated based on the ratio of tensile strength of the fabricated dissimilar joint to the tensile strength of the AA6063 base metal (Table 2).…”

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.

“…Impact strength determines the energy absorbed by the welded joints in a crosssectional area. Generally, Charpy impact was used to measure how easily a crack would initiate in a test specimen and how fast it would propagate once it was started [30]. The 'V' notch was positioned on the weld interface, as shown in Fig.…”

Welding dissimilar metals by fusion welding process is a tough task, as both metals have different thermomechanical properties. In this study, experiments are carried out to join aluminium AA6063-T6 and steel AISI304L dissimilar alloys with different faying surface modifications through a continuous drive friction welding process (CDFW). This study aims to introduce the joining methods and evaluate the performance of their fabricated joints through microstructure and mechanical characterisations. Here, friction time (3, 5, and 7 s) is varied, whereas friction and upset pressures are kept constant. The faying surface-modified specimens are welded at constant chuck rotational speed 1300 rpm. The surface of the AISI304L specimen is buttered with pure aluminium and welded with an AA6063-T6 specimen. Similarly, the faying surface of the AISI304L specimen is tapered and welds with AA6063-T6 specimens having different modifications like a flat, tapered, and internal groove on their faying surfaces. Thus, different welding trials with different friction timings are conducted for each modification. The results of such joining methods like axial shortening, microstructures, EDS spectrums, tensile properties, impact strength, fractography, and Vickers microhardness are discussed and compared in this paper. The surface modifications with friction time improved the strength and 108.8 % joint efficiency.
