Friction Stir Welding (FSW) is a superior metal joining technique for joining similar and dissimilar metals. The various materials acceptable for the FSW techniques were magnesium alloys, mild steel, stainless steel, copper alloys, titanium alloys, aluminium alloys, etc. In this method, the frictional heat generated by the tool on metal workpieces was used for joining, and the workpieces were joined below the upper critical temperature. The substantial benefit of this technique is that it is capable of welding unweldable alloys by the conventional fusion welding method. The welding tool was rotated, traversed, and penetrated into the joint between two base plates. A suitable tool design with appropriate process parameters will result in high-quality welding on workpieces. In these experiments, the tools were designed with different pin profiles. The welding tools required for FSW are designed using SOLIDWORKS, and temperature distributions across the weld regions were analyzed using Ansys software. The fixture needed for FSW is fabricated according to machine requirements. The tool material used was hardened H13 steel, and the base plates were aluminium alloy 6101 and copper alloy C11000. The temperature distributions are noted in each trial during FSW of Al-Cu joints along the weld line region. Due to maximum temperature at weld joints, high ultimate tensile strength and impact strength were obtained at 1200 rpm tool rotational speed and 20 mm/min feed rate with the square pin profile of a hardened H13 steel tool. The obtained ultimate tensile stress (UTS) at joints was less than that of the base plates Al and Cu. The microhardness value was higher at the nugget zone than at the base plates, giving high strength at the joint area and unevenly distributed.

“…Their study evaluated the effects of cutting parameters on material removal rate, surface roughness, and ovality [8]. Kanagaraju et al investigated the drilling performance of super duplex stainless steel used in the marine, petrochemical, and petroleum industries and numerous industrial applications under the conditions of a minimal amount of lubrication technique based on environmentally friendly liquid carbon dioxide and biodegradable coconut oil [9]. Amrit et al investigated the drilling performance of AISI 321 stainless steel using various cooling strategies (dry, wet, and 6 MQL conditions).…”

Vanadis 4E is a versatile powder metallurgical tool steel widely used in today's market with high wear resistance and excellent yield properties. Drilling operations applied to materials are one of the operations commonly used in the machining industry. In drilling operations, coated or uncoated drills are used, which may vary according to the material used. This study applied drilling operation to Vanadis 4E powder metallurgical steel with TiN-coated HSS drills. In the study, Drills with diameters of 5, 8.5, and 10.5 mm, cutting speeds of 22, 23, and 24 m/min, and feed rates of 0.10, 0.12, and 0.14 mm/tooth was used. Nine experiments were carried out using the Taguchi L9 orthogonal array. After the experiments, the material was cut from the holes, and the roughness values were measured from the inner surfaces of the holes. In addition, hardness measurements were made from the material surfaces around the holes. The wear conditions of the drills used in the experiments were examined with an optical microscope after the experiment. The formations after each experiment were also examined. The best roughness value was obtained with the 5 mm diameter drill in the 1st experiment, the best roughness value was obtained in the experiments carried out with the 8.5 mm diameter drill in the 6th experiment, and the best roughness value was obtained in the 7th experiment for the 10.5 mm diameter drill. When the wear in the drills was evaluated, it was observed that the side surface and radial wear occurred.
