However, in the technological bending tests, bending angles within few degrees have been achieved, with a small dependence on the diameter of the bending mandrel.

Welding processes are classified as solid-state joining methods because the melting of joined materials does not occur these processes [ 1 — 3 ]. However, their values have been lower, probably due to the lower pressure spawalnictw during the upsetting phase Table 1. The authors declare that there is no conflict of interests regarding the publication of this paper.

The suitability of aluminium as an alternative material for car bodies. 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. A big attractiveness of these joining methods results from many technical and economic advantages, such as high efficiency and stability of the process or better conditions of occupational safety and spawalnoctwo than in the case of spawaknictwo welding technologies.

Simultaneously, the entire deformation has occurred at the aluminium side Figure 3 b. Pfeifer, Biuletyn Instytutu Spawalnictwa 6 For testing, they have used nonalloy carbon steel with a five spawalnicto higher tensile strength than the tensile strength of aluminium. The results of the butt welding of X5CrNi austenitic steel and Al aluminium alloy were presented in [ 35 ].

The microstructure in the bonding zone of spawlanictwo friction welded AlMg3 aluminium alloy-X10CrNiTi austenitic steel, together with a measurement of microhardness a and a bending test b.

If the period to the highest shearing force value was analysed, then the shearing work was, respectively, for the welding parameters J; J; and J Figure View at Google Scholar M. Xpawalnictwo 9 presents the microstructure of the bonding zone of the friction welded AlMg3 aluminium alloy-X10CrNiTi austenitic steel joint, together with a microhardness measurement. Gawrysiuk, Biuletyn Instytutu Spawalnictwa 3 Effect of Cu-Ag-O electrode on resistance spot welding of aluminium alloy sheet.

Sign in to annotate. The ductility may be evaluated using the technological bending test.

View at Scopus T. For this purpose different process parameters have been used: The intermetallic phases had width of 3. 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. The results, discussed in the previous chapter, showed that joining of pure aluminium and steel, by friction welding, was possible.

The presented review summarizes our actual knowledge about the friction welding of aluminium and aluminium alloys with different types of steel. The deformation was observed behind the titanium layer on the AlMg3 side Figure 20 c. It has turned out that the rough turning of the front surfaced at the nickel side, instead of an accurate turning, has increased the strength of the joint.

The author has been conducting some intensive researches on the friction welding of such joints, partly presented in [ 13 ]. In the case of welding steel to aluminium, the excessively fragile intermetallic compounds lead to the joint degradation.

The joints, analysed in the researches, have been formed with friction times of 1. View of friction welded joints of The welding schedules, electric parameters of welding, electrodes materials and electrodes life time by resistance spot welding aluminium were described. The results of the investigations on the microhardness of such joints are shown in Figure The comparison of shearing work of the friction welded AlMg3 aluminium alloy-austenitic steel joints and the surface area of the aluminium sediment on steel according to [ 26 ].

Another material, which has been tested as an interlayer for the joints of AlMg3 alloy-X10CrNiTi steel, was titanium. The fracture during the tensile test has occurred on the surface of the nickel-aluminium alloy joint. From This Paper Figures, tables, ambroizak topics from this paper. On the edges, this layer has occurred in minor amounts, while in the middle of the joint it did not occur at all, which was related to the lowest rotational speed in this area.

For these reasons, on the welding surface of aluminium alloys that include magnesium, the intensive heterodiffusion and reaction-diffusion processes take place and cause the formation of the intermetallic phases.

An occurrence of a narrow diffusion layer at the joining bound has been stated too. Advances in Materials Science and Engineering. The technological bending test has caused a strong deformation in the pure aluminium interlayer Figures 19 b and 19 c. As it was presented in chapter 2. View of friction welded joints of AlMgSi0.

Aluminum Welding Occupations Robot welding. In this article the comprehensive summary concerning technology of resistance spot welding of aluminium alloys was presented. The researches on the shear energy of the joints have determined its dependence on the thickness of the intermetallic phases. Issue 4 First Online: In the dissertation [ 25 ], the ambfoziak of various aluminium alloys series, and i and S25C ambrozizk carbon steel 0. The top surface of the steel samples has been formed with accurate sample no.

Joining with the welding methods of the pairs ambrozoak materials, such as aluminium alloys-steel, still brings many problems. Topics Discussed in This Paper.

The mechanical properties using, for example, i microhardness measurements, ii tensile tests, iii bending tests, and iv shearing tests were determined. Their forming has influenced the various forms of the flash but has not caused an elimination of the intermetallic spawalnictwi, on the surface aambroziak the materials being bonded Figure
