“…The advantages of this process are, among others, no melting, high reproducibility, short production time and a low energy input. [10][11][12][13][14][15][16][17][18][19] Welding technology is commonly used in many areas. Because it is aimed to provide high and constant quality in manufacturing sector and in products, the importance of non-destructive is the testing methods in quality-control strategies.…”

In this study, X-ray radiographic tests of friction-welded AISI 4340-AISI 2205 steels were investigated. AISI 4340 tempered steel and AISI 2205 duplex stainless steel, each of 12 mm diameter, were used to fabricate the joints. The friction-welding tests were carried out using a direct-drive-type friction-welding machine for different parameters. After this process, the radiographic tests of the welded joints were examined by X-ray diffraction. The experimental results indicated that the AISI 4340 tempered steel could be joined to the AISI 2205 duplex stainless steel using the friction-welding technique and for achieving a weld with sufficient strength. The result of the radiographic tests indicated that by increasing the rotation speed, the friction pressure and the forging pressure, the amount of flash increased for all the specimens. In contrast, when increasing the friction time the amount of flash decreased. The best properties for steels AISI 4340-2205 were observed for the specimens welded at a rotation speed of 2200 min -1 , a friction pressure of 40 MPa, a forging pressure of 80 MPa, a friction time of 6 s and a forging time of 3 s.Keywords: AISI 4340, AISI 2205, friction welding, radiographic test V tej {tudiji so bili rentgensko pregledani spoji jekel AISI 4340-AISI 2205, zvarjeni s trenjem. Spoji so bili izdelani s popu{~e-nim AISI 4340 jeklom in AISI 2205 dupleks nerjavnim jeklom, vsako premera 12 mm. Preizkus varjenja s trenjem je bil izvr{en z uporabo neposredno gnanega stroja za varjenje s trenjem, pri razli~nih parametrih. Po tem postopku so bili zvarjeni spoji pregledani z rentgenom. Rezultati preizkusov so pokazali, da je z varjenjem s trenjem mogo~e spojiti AISI 4340 popu{~eno jeklo in AISI 2205 dupleks nerjavno jeklo in da je mogo~e dobiti zvar z zadostno trdnostjo. Rezultati rentgenskih preiskav so pokazali, da pri nara{~ajo~i hitrosti vrtenja, tornega tlaka in tlaka pri kovanju dele`zmeh~anega roba nara{~a pri vseh vzorcih. Nasprotno pa se pri podalj{anju~asa trenja zmanj{a koli~ina zmeh~anega roba. Najbolj{e lastnosti pri jeklih AISI 4340-2205 so bile opa`ene pri vzorcih, varjenih z rotacijo 2200 min -1 , tornim tlakom 40 MPa, kova{kim tlakom 80 MPa,~asom trenja 6 s iñ asom kovanja 3 s.

“…On Figure 2 distinct regions are seen in the heat-affected zone and the interface of the S1 joint. As reported in the references, the evaluation of the microstructures of the joints revealed different zones in all the samples that were identified as the base metal (BM), the partially deformed zone (PDZ), the deformed zone (DZ) and the fully plasticized deformed zone (FPDZ) 13,15,17 . In S1, some disconnected regions and gaps were observed with SEM.…”

Couples of AISI 304L and AISI 1040 steels were welded using the continuous-drive friction-welding process. The welded joints were manufactured using three different rotational speeds ((1300, 1500 and 1700) r/min), three different frictional pressures and three different frictional times. To determine microstructural changes, the interface regions of the welded samples were examined by scanning electron microscopy (SEM), X-ray diffraction (XRD) and energy dispersive spectrometry (EDS). Microhardness and tensile tests of the welded samples were conducted. The results show that the properties of the microstructures are significantly changed and the interface temperature increased with the frictional time. An excellent tensile strength was observed for the joint made at a rotational speed of 1700 r/min and a frictional time of 4 s. Keywords: friction welding, AISI 1040 steel, AISI 304L steel Jekli AISI 304L in AISI 1040 sta bili zvarjeni z uporabo kontinuirnega tornega procesa varjenja. Zvarjeni spoji so bili izdelani pri treh razli~nih hitrostih vrtenja ((1300, 1500 in 1700) r/min), treh razli~nih tornih tlakih in treh razli~nih tornih~asih. Za dolo~itev mikrostrukturnih sprememb je bilo sti~no podro~je zvarjenega vzorca preiskano z vrsti~nim elektronskim mikroskopom (SEM), z rentgensko difrakcijo (XRD) in z energijsko disperzijsko rentgensko spektrometrijo (EDS). Izvr{eni so bili preizkusi mikrotrdote in natezni preizkusi varjenih vzorcev. Rezultati ka`ejo, da se mikrostruktura omembe vredno spremeni in da se temperatura stika povi{uje s~asom trenja. Odli~na natezna trdnost stika je bila ugotovljena pri spoju s hitrostjo vrtenja 1700 r/min in pri tornem~asu 4 s.

“…When a certain amount of flash metal has occurred, the rotation stops and the compressive force is maintained or slightly increased to consolidate welding [10]. Several studies have been conducted to understand the influence of direct drive friction welding parameters on both microstructure evolution and mechanical properties of post-forging joints such as friction time [11][12][13][14][15][16], friction pressure [10][11][12][13][14][15][16][17], forging phase [18,19] and finally rotation speed [20,21]. This process as mentioned in the literature has two phases.…”

During direct drive friction welding could relatively predicting the micro-structural and mechanical properties of friction-welded joints by controlling the welding conditions; friction time is an important coefficient that effects on these properties, present study focused on the effect of that time on micro-structural and mechanical phenomena during that process. The process achieved in different friction time, while welding joints investigated by macroscope, microstructure, scanning electron microscope, tensile, compression and micro-hardness tests. The micro-hardness tests were performd along the interface and axial direction. Thus, the tensile tests carried out on the standardized test piece with effective diameter of 6 mm and compression tests were extracted at welded center in three angles of 0°, 45° and 90° with test specimen of 4 mm diameter and 6.5 mm length. The results showed that with increasing friction time could be found hard zone at the interface of welded joint because of extended of high plastically deformation zone, which will responsible on decreasing some useful mechanical properties such as ultimate tensile strength and yield compression strength. However, tensile fracture position occurred adjacent to the interface at the thermo-mechanical deformation zone in the rotating side for all welding pieces, where the micro-hardness attenuated at that region.
