“…Pengelasan gesek ditinjau dari sisi cara mentransfer energi mekaniknya, dapat diklasifikasikan secara praktis menjadi pengelasan gesek continuous drive, dan pengelasan gesek inersia [5]. Pengelasan gesek continuous drive merupakan metode pengelasan gesek yang digunakan untuk menyambungkan logam berbentuk selinder dimana terjadi pembangkitan panas akibat gesekan pada permukaan kontak [6].…”

Friction stir spot welding-FSSW has been suggested as effectual process to welding difficult materials such as dissimilar materials and thin sheet of metal alloys. In this study, using dissimilar materials were welded carbon steel-1006 on upper plate and aluminum alloy AA2024-T3 on lower plate. Macrostructure, micro-structural analysis and mechanical properties of the joints are done. The effect of penetration depth, dwell time and spindle speed on tensile shear load are investigated with invariable of other parameter during welding process. The maximum tensile shear load (3.31KN) was occurred when using 0.4mm of penetration depth, 10 sec of dwell time and 1400 rpm of spindle speed. Also, two type of failure shape was observed interfacial fracture of carbon steel sheet and pull-out fracture of AA2024-T3 sheet.

“…[6][7][8] In addition to the parameters of the welding process (time, pressure and speed), a significant impact on the quality of the achieved connection between Al and Cu is also made by the contact surfaces. 9,10 The preparation of the bonding surfaces is of special importance since each type of surface impurities may disturb the required quality level of the joint. 11 Due to the tendencies of Al and Cu to oxidize under ambient conditions, [12][13][14] it is recommended that the cleaning of the contact surfaces of these metals should be performed immediately before the welding procedure.…”

The objective of this research is to consider the effects of certain parameters of the friction-welding process on the morphology of an aluminum/copper joint. The effect of the following parameters was monitored: the operating time, the operating pressure, the forging time and the forging pressure. The speed was constant during the binding process and reached 1500 min -1 . The preparation of the welding materials was performed in accordance with the industrial production conditions. With the SEM-EDS analysis, it was found that the morphology of the Al/Cu interface slightly changes when we change the distance from the rotation axis, irrespective of the combination of the friction-welding parameters. Apart from this, the joined effects of the operating pressure of 48 MPa and the forging pressure of 160 MPa caused a morphological change of the Al/Cu interface, while the forging time at the moment of the combined pressurizing effect significantly influenced the modification of the Al/Cu interface shape within a very narrow time interval of only a few seconds. Keywords: friction welding, bimetallic joint, interface, aluminum, copper, SEM-EDS Cilj te raziskave je obravnava vpliva nekaterih parametrov procesa tornega varjenja na morfologijo spoja aluminij/baker. Pregledan je bil vpliv naslednjih parametrov:~as delovanja, tlak pri obratovanju,~as kovanja in tlak pri kovanju. Hitrost 1500 min -1 je bila med spajanjem konstantna. Priprava materialov za varjenje je bila izvr{ena skladno s pogoji industrijske proizvodnje. S pomo~jo SEM-EDS analiz je bilo ugotovljeno, da se morfologija spoja Al/Cu rahlo spreminja s spreminjanjem razdalje od rotirajo~e osi, ne glede na kombinacijo parametrov procesa tornega varjenja. Poleg tega je skupni u~inek delovnega tlaka 48 MPa in tlaka pri kovanju 160 MPa povzro~il morfolo{ke spremembe spoja Al/Cu, medtem ko~as kovanja, v trenutku kombiniranega stiskanja mo~no vpliva na spremembo oblike Al/Cu spoja v zelo ozkem temperaturnem intervalu samo nekaj sekund.
