Purpose: This study aims to examine the interaction between process parameters and bead geometry, to perform the research to predict optimal bead geometry (bead width, reinforcement height, left leg length, right leg length) through the analysis of experimental data. For this, not only linear and the curvilinear equations were developed to predict bead geometry, but also interactions between pr...

The lightweight titanium alloys possess good resistance to corrosion and temperature. They are used in turbine engines aircraft structures. strength of weld joint is dependent on thermal history the zone bead geometry. quality can be improved by specifying optimal welding parameters. Trial-and-error experimental methods time-consuming expensive. This paper deals with Computational Fluid Dynamic...

Welding is a reliable and effective metal fabrication process which is widely used in industries. High heating at a one location during welding and further rapid cooling generates residual stress and distortion in the weld and base metal. In last few decades various research efforts have been directed towards the control of welding process parameter aiming at reducing residual stress and distor...

A number of welding parameters are responsible for the quality of welds. The modeling of weld bead shape is important for predicting the quality of welds. In this paper, an attempt has been made to develop a back-propagation neural network (BPNN) model for the prediction of reinforcement height and width of bead in GTA bead-on plate welding process. The experimental results were used as testing...

Abstract Additive manufacturing with steel opens up new possibilities for individual parts or complex supply chains. The direct energy deposition process DED-arc, also known as wire arc additive (WAAM), is particularly suited large structures a high degree of geometrical freedom. design freedom makes WAAM ideal creating force-flow-optimized nodes and spaceframes use in the construction industry...

Numerous GMAW processes have appeared for one-pass welding of medium to high thickness. This concept originated in the 1980s with T.I.M.E. technique and 1990s 2000s saw emergence Rapid Arc, Melt Buried Arc techniques. These did not include any special control features, but rather parameter combinations improve bead geometry. A new interpretation factors that are critical achieving performance (...

Submerged arc welding (SAW) is an important metal fabrication technology specially applied to join metals of large thickness in a single pass. In order to obtain an efficient joint, several process parameters of SAW need to be studied and precisely selected to improve weld quality. Many methodologies were proposed in the past research to address this issue. However, a good number of past work s...
