Karakteristik Sifat Mekanik Hasil Pengelasan Gesek Aluminium dengan Tembaga Menggunakan Variasi Kecepatan Putar dan Kekasaran Permukaan Kontak

Friction welding is a type of welding that is used for a variety of materials. Friction welding is a method of joining two materials by swiping them together until they reach some of the melting points of the materials to be joined, then applying constant pressure. Aluminum and copper are the materials to be joined in this study. Using rotational speed and contact surface roughness variations. The purpose of this research is to determine the mechanical properties of friction welding results between aluminum and copper. The speed settings are 1230, 1500, and 2500 rpm. Use sandpaper grades #100, #800, and #1500 to achieve different levels of surface roughness. According to the results of this study, the rotational speed with the highest tensile strength and hardness values is 1230 rpm, namely 59.6 MPa and 54.6 HVN (Al), 112.1 HVN (Al) (Cu). In terms of surface roughness variations, the surface roughness using grade #1500 sandpaper has the highest value, namely 54.18 HVN (Al), 112.1 HVN (Cu). And #100 sandpaper with a value of 52.48 Mpa. The results of the microstructure test in the weld joint area at a magnification of 1000x indicated that the friction welding of aluminum and copper was successful, as evidenced by the diffusion of aluminum and copper in this area.

Optimization of friction welding process parameters for Joining Al6082 and mild steel using RSM

The goal of this research is to evaluate the improvement of solid state joints made of different materials, Al6082 Aluminum and Mild Steel. Rotary friction welding was used to create the joints (RFW). The process parameters of friction welding machine was optimised using response surface methodology (RSM) to achieve the maximum tensile strength of the joint. Dissimilar welding of metals is being a difficult process due to its variance in mechanical properties, co-efficient of thermal expansion, thermal conductivity and other properties. There is a big mismatch between the metals when welded. In this case the friction welding is found out be a better process than other conventional welding. The friction welding of Aluminium and Mild steel was a challenging one due to its difference in mechanical and physical characteristics. One more problem is the formation of intermetallic compounds at the interface. This intermetallics may lead to brittleness at the weld center and giving way for failure. So this should be reduced. In this study the optimization of welding parameter is done by using RSM. Various combinations of parameter has been set and welded. Their tensile properties and characterisation has been analysed.

Analysis of bend angle variation in aluminium – copper friction welding in the presence and absence of nickel interlayer

Friction welding of Aluminium with Copper without interlayer and with Nickel interlayer were performed. Friction welding parameters were Friction pressure, upset pressure and burn-off length. Three levels were chosen for each of these parameters and Taguchi analysis was done, with bend angle as the output parameter. Burn off length followed by friction pressure and upset pressure were found to be the significant parameters for friction welding without interlayer. Friction pressure followed by burn off length and upset pressure were found to be significant parameters for friction welding with Nickel interlayer. The results were analyzed and possible analysis for the results obtained have been given based on friction welding theory.

Friction Welding of Aluminium and Aluminium Alloys with Steel

The paper presents our actual knowledge and experience in joining dissimilar materials with the use of friction welding method. The joints of aluminium and aluminium alloys with the different types of steel were studied. The structural effects occurring during the welding process were described. The mechanical properties using, for example, (i) microhardness measurements, (ii) tensile tests, (iii) bending tests, and (iv) shearing tests were determined. In order to obtain high-quality joints the influence of different configurations of the process such as (i) changing the geometry of bonding surface, (ii) using the interlayer, or (iii) heat treatment was analyzed. Finally, the issues related to the selection of optimal parameters of friction welding process were also investigated.

Linear friction welding of aluminium to magnesium

Joining of an aluminium alloy to a magnesium alloy (AA 6082-T6 to AZ31) has been carried out by linear friction welding. The joining of this material combination is of particular significance for automotive components. Results show that welds with reasonable strength (comparable to the yield strength of the parent materials in O temper) can be produced. Weld microstructures were characterised by backscattered scanning electron microscopy, hardness testing and laboratory based X-ray diffraction. A particular emphasis was placed on determining the effects of welding parameters on the relative amounts of detrimental intermetallic phase at the weld line.

Friction Welding of A 6061 Aluminum Alloy and S45C Carbon Steel

Many researches for friction welding of aluminum with either carbon steel or stainless steel have been carried out. From those results, it is concluded that the greatest problem is the formation of brittle intermetallic compounds at weld interface. However, it is not clearly demonstrated the effect of friction welding parameters on the formation of intermetallic compounds. This research purposes are to evaluate the formation of intermetallic compounds and to investigate the effect of friction welding parameters on the strength of welded joint. For these purposes, A6061 aluminum alloy and S45C carbon steel were used with a continuous drive vertical friction welding machine. Tensile test results revealed that the maximum tensile strength was achieved at extremely short friction time and high upset. The joint strength reached 92% of the tensile strength of A6061 base metal. Tensile strength of friction welding was increasing with increasing upset pressure when friction time 1sec. However, tensile properties were deteriorated with increasing friction time. It was observed that the amount of formed intermetallic compound was increasing with increasing friction time at weld interface. Partly formed intermetallic compound on weld interface were identified when friction time 1sec. However, intermetallic compound layer were severely developed with longer friction time at weld interface. It was concluded that intermetallic compound layer deteriorated the tensile properties of weld joints.
