Corrosion Fatigue Behaviour of Aluminium 5083-H111 Welded Using Gas Metal Arc Welding Method

Pulsed metall inert gas (MIG) welding and its effects on the microstructure and element distribution of an aluminum matrix reinforced with SiC composite material

“…Gas metal arc welding (GMAW) is the most widely used process in aerospace, pipeline, pressure vessel, automotive, and structural industries for welding a wide variety of ferrous and non-ferrous materials. How-ever, some undesirable outcomes can occur when welding aluminum matrix composites reinforced with ceramic particles using those methods [6]. The most important problem in aluminum welding is poor fusion, as a consequence of the oxide layer that forms in the welding region [7].…”

“…If these undesirable situations occur, differences in hardness distribution, brittle welding areas, and porous microstructure can be formed. Precautions should be taken to avoid or minimize these situations [6]. Choosing a proper welding technique and welding parameters is significant in order to obtain optimum properties and good-quality welding structures.…”

“…Aluminum matrix composites require new-generation welding machines to obtain high efficiency. As a consequence of using advanced technological welding machines, low-cost mass-production planning can be performed [6]. Therefore, conventional fusion welding methods have taken place of solid-state welding techniques recently [7,10].…”

“…Metal inert gas technique is one of the subcategories of conventional gas metal arc welding. For heating and melting, an electric arc occurs on be- tween a consumable wire electrode and the workpiece used in gas metal arc welding [6]. The electric arc and the molten weld pool are to be protected from atmospheric contamination.…”

Multiattribute Assessment of Consumables for TIG Welding of Aluminum Alloys

“…Dissimilar aluminum alloys combinations are widely used in aerospace and automobile applications such as inner body panel, heat shields, structural components, ladders, and space frames [1]. Several welding processes such as friction stir welding (FSW) and laser welding are gaining popularity for welding aluminum but TIG welding is still most widely used process for joining aluminum because of its heat control ability (narrow heat affected zone) and eco-friendly nature (no spatter and smoke).…”
