Determination of Coined-Bead Geometry in the V-Bending Process
Advances in Mechanical Engineering, 2014 The coined-bead technique is commonly applied in the V-bending process to eliminate the spring-back feature and to achieve the required bending angle. In the present research, which is based on a stress distribution analysis, the effects of a coined-bead

Effect of the Metal Transfer Mode on the Symmetry of Bead Geometry in WAAM Aluminum [PDF]
Symmetry, 2021 The symmetrical nature in the case of wall fabrication by wire arc additive manufacturing (WAAM) has been observed in the literature, but it has not been studied as a source of knowledge. This paper focuses on the comparative study of three drop transfer methods employing Gas Metal Arc Welding (GMAW) technology, one of the most reported for the ...

Impact of the beam shape and process parameters on bead geometry in WLAM
Additive Manufacturing Letters, 2023 Wire laser additive manufacturing (WLAM) is an emerging process to build rapidly metal parts of low complexity. In this paper, single beads of low alloy carbon steel, ER120, were welded with a filler on a S355J2 substrate to reproduce the conditions met in WLAM. The impact of the process parameters (power, wire feedrate, travel speed, spot size) on the

Automatic Control of the Weld Bead Geometry
, 2021 Automatic control of the welding process is complex due to its nonlinear and stochastic behavior and the difficulty for measuring the principal magnitudes and closing the control loop. Fusion welds involve melting and subsequent solidification of one or more materials.

Prediction and Optimization of Weld Bead Geometry
International Journal of Innovative Technology and Exploring Engineering, 2019 Bead geometry plays very important role in predicting the quality of weld as cooling rate of the weld depends on the height and bead width, also bead geometry determines it’s residual stresses and distortion. Weld bead geometries are outcomes of several welding parameters taken into consideration. If arc travel is high and arc power is kept low it will
