Submerged arc welding also known as sub arc welding has become a chief welding process because of its ability to deposit large amounts of metal with high penetration. The quality of weld depends on bead geometry of the weld which in turn depends on the process variables. This paper deals with the application of factorial design approach for optimising four submerged arc welding parameters viz. ...

The final mechanical and physical properties should be predicted in tandem with the bead geometry characteristics for effective additive manufacturing (AM) solutions processes such as directed energy deposition. Experimental approaches to investigate are costly, simulation time-consuming. Alternative artificial intelligent (AI) systems explored they a powerful approach predict properties. In pr...

The ability to predict the geometry of weld bead plays a key role in accurate path planning and determination welding parameters wire arc additive manufacturing. However, little attention has been paid its prediction when deposition is not straight. Thus, this work focuses on 3D reconstruction based path. One main findings paper that shape changes from symmetrical cross-section straight portion...

The prediction of the weld bead geometry parameters is an important aspect welding processes due to it related strength welded joint. This research focuses on using statistical design techniques and a deep learning neural network predict shape shielded metal arc (SMAW), inert gas (MIG), tungsten (TIG) processes. With techniques, experiments were carried out obtain data for generating regression...

Wire and arc-based additive manufacturing (WAAM) is a rapidly developing technology which employs a welding arc to melt metal wire for additive manufacturing purposes. During WAAM of thin-walled structures, as the wall height increases, the heat dissipation to the substrate is slowed down gradually and so is the solidification of the molten pool, leading to variation of the bead geometry. Thoug...
