Abstract Double-sided friction stir welding (FSW), performed with a pair of rotation tools, was studied in an attempt to increase the joining speed when applied automotive advanced high-strength steels (AHSS). The experiments were on butt joint 1.6-mm-thick 1180 MPa grade steel sheets, and sound welds obtained travel no more than 4 m/min, fairly comparable laser beam (LBW), one conventional pro...

The solid-state welding method known as friction stir (FSW) bonds two metallic work parts, whether the same or different, by plastically deforming base metal. frictional resistance between both workpieces causes them to produce heat, which produces plastic deformation and welds them. However, weldability strength of FSW joints mainly depend on parameters. This review highlights previous researc...

Alternative methods for dissimilar metal joining particularly aluminium and copper have gain interest in manufacturing sectors. Friction stir spot welding was carried out on the AA6061 C11000 wires of 2 mm diameter. This research paper reported results microstructures mechanical properties spot-welded joints, also special attention is provided electrical resistivity welds. The reveal informatio...

The current work was carried out to characterize welding of AISI 310 austenitic stainless steel to Inconel 657 nickel-chromium superalloy. The welds were produced using four types of filler materials; the nickel-based corresponding to Inconel 82, Inconel A, Inconel 617 and austenitic stainless steels 310. Of the two joints involved, this paper describes the choice of welding consumables for the...

The height of the unwelded root part in T and X welds whose length exceeds the sound-beam width at the contact point between the sound and the reflector can according to methods known today only be estimated by applying the tandem technique with two ultrasonic transverse probes from one single access area, or two access areas, the latter usually not possible in practice. However, with sheets ha...

The safe-end of a steam generator (SG) nozzle dissimilar metal weld (DMW) for pressurized water reactors (PWRs) is the weakest point failure which crucial safe operation nuclear power station. Related to materials micro-structures, uniaxial stress–strain relationship basic input parameter plant design, safety evaluation, and life management. In this paper, micro-structure tensile mechanical pro...

The influence of titanium alloy (Ti–5Al–2.5Sn) and commercially pure (cpTi) as fillers on dissimilar pulsed tungsten inert gas weldments Ti–5Al–2.5Sn/cpTi was investigated in terms microstructure, mechanical/nano-mechanical properties, residual stresses. A partial martensitic transformation observed the for all welding conditions due to high heat input. microstructure evolved FZ/cpTi interfacia...
