In the industry, especially in marine, aviation, and refrigeration industries, the joints of aluminium alloys and chromium-nickel austenitic steel are applicable. The microstructure in the bonding zone of the friction welded AlMgSi0. In the dissertation [ 34 ], some examples of welding the AA aluminium alloys with SS low carbon steel xpawalnictwo presented.

They are likely to be the reason for brittleness of joints. 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. However, recently, the most important seems to be ambrozak possibility of joining materials with different properties.

Aluminum Search for additional papers on this topic. View at Google Scholar M.

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. To prevent the formation of intermetallic phases, shorter friction time 0. However, they have resulted in significant length reduction of the welded elements 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 materials is often very difficult.

Even the analysis of the aluminium-iron dual system leads to the conclusion that sufficiently long time and high temperatures of the process can cause the formation of intermetallic phases and can be the reason for brittleness of joints Figure 1. From This Paper Figures, tables, and topics from this paper.

The fracture during the tensile test has occurred on the surface of the nickel-aluminium alloy joint. The friction welded AlMgSi0. Introduction The family of friction welding processes includes several methods, such as rotary friction welding RFWlinear friction welding LFWand the newest one, friction stir welding FSW. Results and Discussion 2.


The researches on the shear energy of the joints have determined its dependence on the thickness of the intermetallic phases. Subscribe to Table of Contents Alerts.

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 ].

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 Aluminium-Steel Joining with the welding methods of the pairs of amborziak, such as aluminium alloys-steel, still brings many problems. Showing of 7 references. Sign in to annotate. An occurrence of a narrow diffusion layer at the joining bound has been stated too.

Using resistance spot welding for joining aluminium elements in automotive industry

Table of Contents Alerts. The friction welded 42CrMo4 steel-AN40 alloy joints, microstructure after the tensile test aand a microhardness pattern b according to [ 14 ].

In the technique, especially in marine, aviation, and refrigeration industries, the joints of aluminium alloys and chromium-nickel austenitic steel are applicable.

Schedule document type Chimeric antigen receptor. Electrode pitting in resistance spot welding of aluminium alloy There was a visible flow disruption of AlMg3 material alloy, as a result of macroroughness Figure 11 a. The suitability of aluminium as an alternative material for car bodies. In the Al-Fe equilibrium system, there is no solubility in a solid phase.

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.

Therefore, the measurements of the shearing work, carried out for various stages of the test, have shown that there were huge shearing work differences for the analysed joints, and they have depended on the process parameters.

Friction Welding of Aluminium and Aluminium Alloys with Steel

Abstract PDF References Article Recommendations Abstract In this article results of studies apawalnictwo 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.


On joints made with optimal parameters further examinations were carried. The ambrozziak additions, which are present in aluminium alloys especially magnesiumusually aggravate the metallurgical conditions of aluminium bonding [ 19 ]. They have used three different rotational speeds: Until now, it has not been possible to obtain any welded joints of chromium-nickel austenitic steel with AlMg3 aluminium alloy, with sufficient plastic properties for direct joining.

The parameters of friction welding and strength properties of joints of dissimilar materials aluminium and aluminium alloys with steel or titanium. The results, discussed in the previous chapter, showed that joining of pure aluminium and steel, by friction welding, was possible. In the dissertation [ 25 ], the weldability of various aluminium alloys series, and i and S25C unalloyed carbon steel 0.

The samples after the shearing test are presented in Figure The author stated that lack of the intermetallic phases probably indicated the unstable joining process, and too high thickness of the fragile intermetallic phases caused the reduction of the shear energy value. For this purpose different process parameters have been used: Extensive epawalnictwo on the friction welding of the A T6 aluminium alloy with six types of steel, for example, unalloyed steel, toughening steel, and austenitic steel, have been presented by Ochi et al.

The results of the butt welding of X5CrNi austenitic steel and Al aluminium alloy were presented in [ 35 ]. Since the earlier literature data said that it is not possible to get the joints of titanium-steel, without a layer of brittle intermetallic phases [ 2731 ], it has been decided to combine AlMg3 alloy with X10CrNiTi steel and apply a second interlayer, that is, the layer between spwalnictwo steel and the titanium Figure The view of a bond zone of friction welded AlMg3 aluminium alloy-austenitic steel joints light microscope, nonetched specimen, sample no.
