This study investigates an analytical beam model to improve the analyses of welded thin plates with welding-induced curved distortions. The addresses rigidity a butt-welded joint and its effect on plate bending structural stress by including rotational spring at end. stiffness, ka, is replaced fixity factor, ?a. validity based assumption small displacement moderate rotation mid-plane plate. Usi...

This study investigates four different joints under fluctuating tension cycles in the low-cycle fatigue (LCF) regime. The selected material was S960 ultra-high-strength steel, manufactured via direct-quenching manufacturing route. Based on typical engineering solutions, following were chosen to be investigated experimental tests: metal active gas and laser welded butt joints, fillet-welded load...

This paper presents a study on optimization of process parameters using particle swarm optimization to minimize angular distortion in 202 grade stainless steel gas tungsten arc welded plates. Angular distortion is a major problem and most pronounced among different types of distortion in butt welded plates. The process control parameters chosen for the study are welding gun angle, welding speed...

This study reports the welded joint of a novel 590 MPa V-N microalloyed wheel steel on microstructure and mechanical properties after flash butt welding. The welding parameters were current 48°/582.0 A, upsetting 44°/516.6 workpiece clearance 1.5 mm. evolution in occurred as follows: seam (ferrite side plate + acicular ferrite +martensite)→coarse-grained zone (acicular granular bainite)→fine-gr...

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...
