The view of a bond zone of friction welded AlMg3 aluminium alloy-austenitic steel joints light microscope, nonetched specimen, sample no. The suitability of aluminium as an alternative material for car bodies. Their formation has depended on the diffusion processes that were accelerated by magnesium and their thickness has depended on the welding parameters especially on the friction time.

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. Elliott ambroaiak Wallach [ 16 ] and authors of the elaboration [ 7zpawalnictwo ] have come to similar conclusions.

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. When the thickness was lower than 0. However, their values have been lower, probably due to the lower pressure used during the upsetting phase Table 1.

Effect of Cu-Ag-O electrode on resistance spot welding of aluminium alloy sheet. However, they have resulted in significant length reduction of the welded elements The researches on the shear energy of the joints have determined its dependence on the thickness of the intermetallic phases. The xpawalnictwo of the joint after the friction welding is presented in Figure 23 aand the view of the joint after removal of the flash with a visible interlayer from nickel can be seen in Figure 23 b.

Despite the short time of the welding process and the high pressure during the upsetting sample no.

Advances in Materials Science and Engineering

Electrode pitting in resistance spot welding of aluminium alloy Results and Discussion 2. 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. Aluminum Welding Occupations Robot welding. For testing, they have used nonalloy carbon steel with a five times higher tensile strength than the tensile strength of aluminium.

Showing of 6 extracted citations. But the alloying additions, which are present in aluminium alloys especially magnesiumusually aggravate the metallurgic conditions of aluminium bonding. Pfeifer, Biuletyn Instytutu Spawalnictwa ambrozziak The quality of the joints has been evaluated on the base of static tensile test and microhardness measurements.

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. Spawalnictqo friction welded AlMgSi0.

The view of the joint after the friction welding of 42CrMo4 steel-AN40 alloy with nickel interlayer, directly after the welding aafter spawalnictqo of the flash band the macrostructure of the joint c. The welding of aluminium and its alloys. To prevent the formation of intermetallic phases, shorter friction time 0.

In the industry, especially in marine, aviation, and refrigeration industries, the joints of aluminium spawalnnictwo and ambfoziak austenitic steel are applicable. The results of shearing work of the investigated AlMg3 aluminium alloy-X10CrNiTi, austenitic steel joints, determined for two variants of shearing pattern according to [ 26 ]. 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.

Braze-welding ; Intermetallic compound phase ; high power diode laser ; brazing. 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 ]. 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 different research issues that can occur during friction welding of dissimilar materials were described in this paper. By clicking accept or continuing to use the site, you agree to the terms outlined in our Privacy PolicyTerms of Serviceand Dataset License.

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. 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 welding schedules, electric parameters of welding, electrodes materials and electrodes life time by resistance spot welding aluminium were described.

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

Gawrysiuk, Biuletyn Instytutu Spawalnictwa 3 The ductility may be evaluated using the technological bending test. 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.

For the material of this layer the pure Al 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.

The alloying additions, which are present in aluminium alloys especially magnesiumusually aggravate the metallurgical conditions of aluminium bonding [ 19 ]. 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.

In the dissertation [ 25 ], the weldability of various aluminium alloys series, and i and S25C unalloyed carbon steel 0. However, recently, the most important seems to be the possibility of joining materials with different properties. Another material, which has been tested as an interlayer for the joints of AlMg3 alloy-X10CrNiTi steel, was titanium.

The samples of aluminium alloy have been additionally etched and then washed in ethyl alcohol again.
