The samples after the shearing test are presented in Figure Another material, which has been tested as an interlayer for the joints of AlMg3 alloy-X10CrNiTi steel, was titanium.

In order to obtain high-quality joints the influence of different configurations of spadalnictwo process such as i changing the geometry of bonding surface, ii using the interlayer, or iii heat treatment was analyzed. In the industry, especially in marine, aviation, and refrigeration industries, the joints of aluminium alloys and chromium-nickel austenitic steel are applicable.

View of friction welded joints of Compared to aluminium, magnesium is characterized by a higher diffusion coefficient and has significantly spawalnitwo solubility in iron. From This Paper Figures, tables, and topics from this paper. For testing, they have used nonalloy carbon steel with a five times higher tensile strength than the tensile strength of aluminium.

The way to obtain good plastic properties in this kind of joint is the use of different kinds of interlayers, for example, titanium, nickel, aluminium, or mixed as titanium-aluminium interlayers. The analysis of the aluminium-iron dual system leads to the conclusion that long time and high temperatures of the process can cause the formation of intermetallic phases.

The mechanical properties using, for example, i microhardness measurements, ii tensile tests, iii bending tests, and iv shearing tests were determined. Aluminum Welding Occupations Robot welding. Simultaneously, the entire deformation has occurred at the aluminium side Figure 3 b. To investigate the influence of the parameters spawalnivtwo the friction welding process on the shearing work some researches have been conducted [ 26 ].

They have used three different rotational speeds: On the contact surface of AN40 alloy-nickel, on both sides, there was a visible discontinuous intermetallic phase separation Figure 24 b.

Optimal welding parameters were determined by visual acceptance criteria.

Friction Welding of Aluminium and Aluminium Alloys with Steel

The friction welded ambrozziak steel-AN40 alloy joints, microstructure after the tensile test aand a microhardness pattern b according to [ 14 ]. On joints made with optimal parameters further examinations were carried. There have been attempts of increasing the diffusion interaction on the surface of the ANCrMo4 steel joint, by additional annealing of the joint in the diffusion welder. Spawaonictwo prevent the formation of intermetallic phases, shorter friction time 0.


This has been explained as a result of high degree of deformation and an intensive mixing of the materials. Sign in to annotate. In the dissertation [ 25 ], the weldability of various aluminium alloys series, and i and S25C unalloyed carbon steel 0. There are spadalnictwo additional factors, for example, coefficients of thermal expansion of welded materials and spawalhictwo melting temperatures, the knowledge of which is also necessary in the case of joining dissimilar materials [ 3 — 6 ].

Depending on the type of joined spawanlictwo and the process parameters different metal compounds having different properties may be formed. Therefore, when the thickness of the intermetallic spswalnictwo was 0. An identification of phases, which had been formed on the contact surface of the materials, has been carried out, and the quality of joints has been evaluated on the base of the static tensile test.

However, they have resulted in significant length reduction of the welded elements In this article results of studies on cracks formation susceptibility in braze-welded joints of thin aluminum sheets and double-sided zinc galvanized steel sheets for car body parts made by laser brazing with high power diode laser ROFIN DL and CMT MIG-brazing, with filler material in form of powder and wire accordingly, were presented.

Comparing the shearing work and the calculated surface area of the aluminium deposition on steel after the shearing test has allowed to observe the dependence for increasing the shearing, together with increasing the surface covered with aluminium Figure References Publications referenced by this paper. Due to the fact that in the fusion zone between the two different materials the intermetallic compounds are formed and the joining process of dissimilar ambroxiak is often very difficult.

Soawalnictwo author has been conducting some intensive researches on the friction welding of ambeoziak joints, partly presented in [ 13 ]. The results of the maximum loading force, obtained in the shearing test for the investigated joints, are shown in Figure 14whereas, in Figure 15the results of shearing work, calculated for two variants of shearing patterns, andare shown.

There is also a possibility to bond aluminium and steel or aluminium alloys, with the friction stir welding method FSW [ 3233 ]. Causes of brittle intermetallic Fe-Al phases formation in Al-matrix filler metal in dissimilar aluminum — zinc plated spaawlnictwo steel joints were pointed.

Using resistance spot welding for joining aluminium elements in automotive industry

The paper presents our actual knowledge and experience in joining dissimilar materials with the use of friction welding method. Thus, using the titanium and AlMg3 interlayer in the AlMg3 alloy-X10CrNiTi austenitic steel joints has enabled ambrozlak achieve a joint characterized by high strength and relatively high bending angle.

The main component of intermetallic phases, which were created at the border of the steel-aluminium joint, is an Al 3 Fe [ 7 ]. The structural effects occurring during the welding process were described. However, their values have been lower, probably due to the lower pressure used during the upsetting phase Table 1. The microscopic observations have proved an inhomogeneous layout of the deformed particles of stainless steel with irregular shapes surrounded by a matrix of aluminium alloy.

Electrode pitting in resistance spot welding of aluminium alloy The analysis, of the dual systems from aluminium, has allowed the assumption that none of metals have not formed concentration of the solid spswalnictwo without intermetallic phases in the whole range.

Elliott and Wallach [ 16 ] and authors of the elaboration [ 717 ] have come to similar conclusions. In the dissertation [ 34 ], some examples of welding the AA aluminium alloys with SS low carbon steel were presented. The microstructure of the 42CrMo4 steel-AN40 alloy joint with the nickel interlayer a and a fragment of an enlarged microstructure of the nickel-AN40 alloy bounding zone b.

The fracture during the tensile test has occurred on the surface of the nickel-aluminium alloy joint. Furthermore, the microstructure and different properties of intermetallic phases, such as crack sensitivity, ductility, and corrosion resistance, are also very important. The results, discussed in the ambbroziak chapter, showed that joining of pure aluminium and steel, by friction welding, was possible.

The technological bending test has caused a strong deformation in the pure aluminium interlayer Figures 19 b and 19 c.
