Surface cracks in butt-welded joints usually occur places with increased stress concentrations. The concentration factor (SCF) can be calculated using an empirical equation, five geometric parameters of a joint (thickness the base material, toe radius, weld angle, width, and reinforcement height). However, industrial environment, it is impractical sometimes even impossible to measure all suffic...

An analysis was made of the application Stud Welding hardware welding technologies depending on welded structures used, duration process, shape stud butt and consumables used. The use CD technology for metalware to thin-sheet panels is substantiated. essence process formation a joint described, which consists in explosive evaporation protrusion at end during discharge capacitor banks, excitatio...

In order to ensure high weld qualities and structural integrity of engineering structures, it is crucial detect areas stress concentrations along seams. Traditional inspection methods rely on visual manual geometry measurements. Recent advances in the field automated measurement techniques allow virtually unrestricted numbers inspections by laser measurements profiles; however, compare differen...

Tungsten Inert Gas (TIG) welding is a widely applied manufacturing process. Angular distortion is a major problem and most pronounced among different types of distortion in the butt welded plates. This angular distortion is mainly due to nonuniform transverse shrinkage along the depth of the plates welded. Restriction of this distortion by restraint may lead to higher residual stresses. However...

PURPOSE This study was conducted to evaluate the influence of the implant-abutment connection design and diameter on the screw joint stability. MATERIALS AND METHODS Regular and wide-diameter implant systems with three different joint connection designs: an external butt joint, a one-stage internal cone, and a two-stage internal cone were divided into seven groups (n=5, in each group). The in...

Abstract The joining process of bainitic rails is significant in terms their industrialization high-speed and heavy-loaded railways. This paper demonstrates the microstructure changes critical zone welded joint, which responsible for greatest deterioration mechanical properties. Extensive progress decomposition retained austenite ferrite occurs low-temperature heat-affected (LTHAZ) flash-butt j...

Welding parameters for pipe joint friction stir welding (FSW) have been identified based on L-9 orthogonal arrays used in the Taguchi Method. Different parameters, such as rotation speed, travel speed and axial force, to produce several quality welded AA6063 butt joints. The reliability of products obtained FSW process can be improved through identification optimum combination parameters. Weld ...
