Gas metal arc welding (GMAW), sometimes referred to by its subtypes metal inert gas (MIG) welding or metal active gas (MAG) welding, is a semi-automatic or automatic arc welding process in which a continuous and consumable wire electrode and a shielding gas are fed through a welding gun. A constant voltage, direct current power source is most commonly used with GMAW, but constant current systems, as well as alternating current, can be used. There are four primary methods of metal transfer in… Expand
Welding by Metal-Electrolyte Discharge
A new welding method by using metal-electrolyte discharge has been demonstrated. This method that needs only a common 220 V power supply and a common salt solution, can be used to weld metal wiresExpand
Heat Input Reduction in Fillet Welding Using Bypass and Root Opening
Submerged arc welding (SAW) is a widely used process. Similar to conventional gas metal arc welding (GMAW) (Refs. 1, 2) and flux cored arc welding (FCAW) (Refs. 3, 4), it melts a continuously fedExpand
Gas Metal Arc Welding By Taguchi Technique
MS-1018 is non-hardened ductile steel belonging to low carbon steel groups. It has been extensively used for machining applications such as machine parts, rods, bolts, studs, etc. It indicates thatExpand
Observation of weld pool profiles in short-circuiting gas metal arc welding
Short-circuiting gas metal arc welding (GMAW), a main joining process for light-weight steel structures, is a complex, strongly non-linear, dynamic, and multi input/output process. It is essential toExpand
Low oxidation potential shielding gas instability in GMA welding
Abstract Gas metal arc (GMA) welding is one of the most important processes for joining metals. However, this process is characterised by a relatively large number of variables and high sensitivityExpand
Design and realization of a welding oscillator
Welding is one of the most popular methods to combine metal pieces in manufacturing processes. Arc welding, among all welding techniques, is the most commonly used in manufacturing due to its costExpand
Study of Mechanical Properties and Weldability of Aluminium Alloy and Stainless steel by Gas Metal Arc Welding
Abstract Aluminium-Steel joints which find application in the area of aerospace, automotive and shipbuilding industry aims to reduce the weight of structure thereby enhancing the efficiency. WeldingExpand
Usability of arc types in industrial welding
Arc behaviour is a significant factor in all arc welding processes. Understanding of arc types and their inherent properties can help enhance weld prediction and weld quality and reduce welding costExpand
Welding Distortion Can be Mitigated if Welding Current and Traveling Speed Vary Optimized Along a Weld Path
Typically, the distortion from welding is mitigated with the use of fixtures, clamps, tack welds and so on. Also the welding current and traveling speed are normally set constant during welding alongExpand
Measurement and calculation of arc power and heat transfer efficiency in pulsed gas metal arc welding
Abstract This study investigates the heat transfer efficiency of the pulsed gas metal arc welding (GMAW-P) process. The arc power and heat input were calculated from arc current and voltageExpand
