St-Cu (stainless steel and copper) parts were friction welded with the aim to optimize the process parameters in the present study. The joints obtained with various process-parameter combinations were subjected to a tensile test. Empirical relationships were developed to predict the strength of the joints using RSM (the response-surface methodology) and the coherency of the model was tested. The tensile properties, microhardness variations, SEM, the EDS analysis and X-ray diffraction (XRD) analysis of the welded specimens were evaluated. It was found, with an ANOVA analysis, that the friction pressure/friction time relation has the largest influence on the tensile strength of the joints followed by the rotational speed. However, it was also found that the formation of intermetallics at the interface is responsible for a higher hardness and lower tensile strength of the friction-welded stainless steel-copper joints. Keywords: friction welding, metallurgy, response-surface methodology, tensile strength V predstavljenem delu so bili deli St-Cu (nerjavno jeklo in baker) torno varjeni z namenom optimizacije procesnih parametrov. Spoji, dobljeni z razli~nimi procesnimi parametri, so bili preizku{eni z nateznim preizkusom. Razvite so bile empiri~ne odvisnosti za napovedovanje trdnosti spojev s pomo~jo RSM (Metodologija odgovora povr{ine) in izvr{ena je bila koherenca modela. Ocenjene so bile natezne lastnosti, spreminjanje mikrotrdote, SEM, EDS analiza in rentgenska difrakcija (XRD) zvarjenih vzorcev. Iz ANOVA analize je bilo ugotovljeno, da ima torni tlak/~as trenja najve~ji vpliv na natezno trdnost spojev, sledi pa mu hitrost vrtenja. Ugotovljeno je bilo, da je ve~ja trdota in manj{a natezna trdnost torno varjenih spojev posledica nastanka intermetalne zlitine na stiku nerjavno jeklo-baker. Klju~ne besede: torno varjenje, metalurgija, metodologija odgovora povr{ine, natezna trdnost

UNS S 32205 duplex stainless steel specimens were joined by continuous drive friction welding process. The experiments were conducted as per the Taguchi (L16 orthogonal array) method. The friction welding process parameters such as heating pressure, heating time, upsetting pressure, upsetting time, and speed of rotation were fixed with low, medium, and high levels of range based on the machine capacity, and the required knowledge was acquired from the preliminary experiments. The joint characterization studies included micro structural examination and evaluation of mechanical properties of the joints. Microhardness variation, impact toughness, and tensile strength of the joints were evaluated. Neither a crack nor an incomplete bonding zone was observed. The tensile strength of the joints was higher than the strength of the base material, and the friction and upsetting pressures were found to influence the joint strength. The tensile strength of all the welds was observed to be increasing with an increase in the rotational speed. The toughness of the friction welds was evaluated at room temperature and also at subzero (cryo) temperature conditions. The toughness for friction welds was found to be superior to the fusion welds of duplex stainless steel at room temperature and cryo conditions. Weldments exhibited better corrosion resistance than the parent material.

“…Friction welding is one of the methods with a large share among the other conventional welding methods. The most important parameters in friction welding are friction time, friction pressure, forging time, forging pressure and rotational speed (Uzkut 1999;Şahin and Akata 2003).…”

In this study, different welding parameters were applied to two different steels with high alloys and mechanical and metallographical investigations are performed. Thus, the optimum welding parameters were determined for these materials and working conditions. 12⋅30 diameter steel bars made up of 1⋅4871 (X53CrMnNiN219) and 1⋅4718 (X45CrSi93) steel were used as experimental material. The material loss increased with increase in friction and rotating pressure. No fracture at the welding region was observed and the highest fracture energy was identified in B5 group. Based on micro hardness investigation; the hardness profile reached its minimum value at the welding region.
