If the period to the highest shearing force value was analysed, then the shearing work was, respectively, for the welding parameters Spawalniictwo J; and J Figure Topics Discussed in This Paper. The chemical compound of the tested materials according to [ 14 ]. However, their values have been lower, probably due to the lower pressure used during the upsetting phase Table 1.

Seli and coauthors [ 10 ] have tried to model the heat distribution during the friction welding of aluminium and structural steel and connect it with the formation of intermetallic phases.

Abstract PDF References Article Recommendations Abstract In this article results of studies on cracks formation susceptibility in braze-welded joints of thin aluminum sheets and double-sided zinc galvanized spawalnixtwo 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.

The view of the joint after the friction welding of 42CrMo4 steel-AN40 alloy with nickel interlayer, directly after the welding aafter removal of the flash band the macrostructure of the joint c. Equilibrium diagram for the aluminium-iron system according to [ 15 ].

The view of the joint after the friction welding is presented in Spaealnictwo 23 aand the view spawxlnictwo the joint after removal of the flash with a visible interlayer from nickel can be seen in Figure 23 b. During the friction welding of pure aluminum with austenitic steel intermetallic phases are formed, but the mechanical properties of the joints strength and the plasticity are still good and breaking occurs on the aluminum side.


From This Paper Figures, tables, and topics from this paper. The author has been conducting some intensive researches on the friction welding of such joints, partly presented in [ 13 ]. Comparing the shearing work spswalnictwo 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 Such joint was supposed to replace the previous mechanical bonding of the shaft and rotor, produced from these materials and used in some types of turbo boost in large turbo diesel engines.

Showing of 6 extracted ambrozaik. However, in the technological bending spawanictwo, bending angles within few degrees have been achieved, with a small dependence on the diameter of the bending mandrel.

In the case of welding steel to aluminium, the excessively fragile intermetallic compounds lead to the joint degradation. The author stated that lack of the intermetallic phases probably indicated the spawalnitcwo joining process, and too high thickness of the fragile intermetallic phases caused the reduction of the shear energy value.

The structural effects occurring during the welding process were described.

Using resistance spot welding for joining aluminium elements in automotive industry

Despite the short time of the welding process and the high pressure during the upsetting sample no. Pfeifer, Biuletyn Instytutu Spawalnictwa 6 On joints made with optimal parameters further examinations were carried.

Wherein, the highest values average of The results of the investigations on the microhardness of such joints are shown in Figure 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. Skip to search form Skip to main content. The surfaces of the samples for friction welding have been prepared with turning and washed in ethyl alcohol, directly before welding.

This has been explained as a result of high degree of deformation and an intensive mixing of the materials. References Publications referenced by this paper.

Thus, using the titanium and AlMg3 interlayer in the AlMg3 alloy-X10CrNiTi austenitic steel joints has enabled to achieve a joint characterized by high strength and relatively high bending angle.

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. Therefore, when the thickness of the intermetallic phases was 0.

The microstructure spawalnictwl the joint is shown in Figure However, they have resulted in significant length reduction of the welded elements Using of such high diameters of the samples has been determined by the desire to achieve the most accurate approximation of the research for their utilitarian purpose. The samples after the shearing test are presented in Figure To obtain high-quality joint it is necessary to know and analyze phase diagram of the two welded materials.

In the dissertation [ 34 ], some examples of welding the AA aluminium alloys with SS low carbon steel were presented.

Friction Welding of Aluminium and Aluminium Alloys with Steel

The view of a bond zone of friction welded AlMg3 aluminium alloy-austenitic steel joints light microscope, nonetched specimen, sample no. Strength properties of the steel-aluminium joint, welded at various parameters according to [ 17 ]. The friction welded 42CrMo4 steel-AN40 alloy joints, microstructure after the tensile test aand a microhardness pattern b according spawalnitwo [ 14 ].
