A detailed microstructural characterisation of the emerging weld-line grain structure, for bead-upon-plate welds in Ti-6Al-4V (Ti64) differing plate thickness, was performed. The microstructure studied formed during both steady state and non-steady sections within weld path, with portion being taken from end as bead heat source overhang edge plate. This allows effects welding process conditions...

This paper presents a modeling method of weld bead profiles deposited on uneven base metal surfaces and its application in multi-pass welding. The robotized tungsten inert gas welding requires precise positioning the beads to avoid defects achieve desirable join since shapes depend surface previously beads. proposed model consists fuzzy systems estimate coefficients profile function. characteri...

The symmetrical nature in the case of wall fabrication by wire arc additive manufacturing (WAAM) has been observed literature, but it not studied as a source knowledge. This paper focuses on comparative study three drop transfer methods employing Gas Metal Arc Welding (GMAW) technology, one most reported for manufacture aluminum alloys. modes are well-known pulsed GMAW, cold arc, and newer AC. ...

Abstract Gas metal arc welding (GMAW) process is one of the most important in industry, so different efforts have been made to anticipate parameters convert this into a stable capable joining parts with minimum human interference. In sense, controlling essential for automated applications because properties such as weld mechanical strength are defined by composition, microstructure, and bead ge...

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...

The present paper describes fuzzy logic simulation of shielded metal arc welding (SMAW) process to predict the Quality of weld joint. It describe the quality of weld joint & effect of welding current, voltage and welding speed on tensile strength of shielded metal arc pipe welded mild steel joints. An ERW Mild steel pipe I S 1239 of 6 mm thickness and 150 mm diameter were used as the base mater...
