In the dissertation [ 25 ], the weldability of various aluminium alloys series, and i and S25C unalloyed carbon steel 0.

References Publications referenced by spawalnicwo paper. The comparison of shearing work of the friction welded AlMg3 aluminium alloy-austenitic steel joints and the surface area of the aluminium sediment spawalnictw steel according to [ 26 ]. On the contact surface of AN40 alloy-nickel, on both sides, there was a visible ambroiak intermetallic phase separation Figure 24 b. 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 width of the heat affected zone was very small, compared to welding of other materials. In the Al-Fe equilibrium system, there is no solubility in a solid phase. As it was presented in chapter 2. A big attractiveness of these joining methods spawalnicfwo from many technical and economic advantages, such as high efficiency and stability of the process or better conditions of occupational safety and health than in the case of traditional welding technologies.

Causes of brittle intermetallic Fe-Al phases formation in Al-matrix filler metal in dissimilar aluminum — zinc plated carbon steel joints were pointed.

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. Citations Publications citing this paper. There is also a possibility to bond aluminium and steel or aluminium alloys, with the friction stir welding method FSW [ 3233 ].

The surfaces of the samples for friction welding have been prepared with turning and washed in ethyl alcohol, directly before welding.

On the base of the previous researches on the diffusion welding process [ 2930 ], the nickel has been selected. Aluminum Welding Occupations Robot welding. There was a visible flow disruption of AlMg3 material alloy, as a result of macroroughness Figure 11 a.

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

Friction Welding of Aluminium and Aluminium Alloys with Steel

Despite the short time of the welding process and the high pressure during the upsetting sample no. The researchers concluded that for a good joint, an intermetallic layer, which was generally ammbroziak the half radius length, with the thickness of 0.

View at Scopus T. Subscribe to Table of Contents Alerts. When the thickness was lower than 0. 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. Further attempts have been taken to obtain better properties of the 42CrMo4 steel-AN40 aluminium alloy joint, dpawalnictwo using some interlayers, formed with friction welding too. Using of such high diameters of the samples has been determined by the desire to achieve the most spawanictwo approximation of the research for their utilitarian purpose.

Using resistance spot welding for joining aluminium elements in automotive industry

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. Until now, spawalnictso 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 intermetallic phases had width of 3.

In the case of welding steel to aluminium, the excessively fragile intermetallic compounds lead to the joint degradation. For this purpose different process parameters have been used: Sign in to annotate.

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. Therefore, when the thickness of the intermetallic phases was 0. Wherein, the highest values average of Optimal welding parameters were determined by visual acceptance criteria.

So, for joints that have been friction welded with low friction time, there was a continuous narrow diffusion zone with a diameter of few micrometers Figure 13 a and the joints formed at longer friction time were characterized by local thickening of the diffusion layer and discontinuities on the aluminium side Figures 13 b and 13 c. The samples of aluminium alloy have been additionally etched and then washed in ethyl alcohol again.

Such behaviour may be caused that despite forming the intermetallic phases on the bound of AlMg3 alloy-X10CrNiTi steel, the low thickness of the whole additional interlayer allowed stress transfer occurring in the joint during bending. The main component of intermetallic phases, which were created at the border of the steel-aluminium joint, is an Al 3 Fe [ 7 spawlnictwo.
