In recent years, ultra-high-strength structural (UHSS) steel in quenched and tempered (Q+T) conditions, for example, S960QL has been found wider application areas such as structures, cranes, trucks due to its extraordinary material properties acceptable weldability. The motivation of the study is investigate unique capabilities electron beam welding (EBW) compared conventional gas metal arc (GM...

Consumable DE-GMAW is an innovative welding process, which can significantly increase the deposition rate without raising the base metal heat input to an undesired level. To be qualified as a practical manufacturing process, feedback control is required to assure the presence and stability of the bypass arc. To this end, the bypass arc voltage was selected to monitor the state of the bypass arc...

The oscillating phenomenon of the weld pool has a direct physical correspondence with its penetration state, which broad application prospects in monitoring states. This article studied characteristics short-circuiting gas metal arc welding (S-GMAW) different states based on high-speed photography system. results show that form liquid bridge electric explosion impact is “surface impact” S-GMAW....

The weld penetration under different plasma welding currents was compared in the plasma-gas metal arc (GMAW) hybrid of aluminum alloy. When current lower than 150 A, greater sum single and GMAW penetration. reached 130 with increase current, advantage gradually weakened, that welding. above change mechanism is revealed from heat source energy distribution molten pool stress. results show when 1...

In industries and research organizations most widely used welding methods are shield metal arc welding (SMAW), gas metal arc welding (GMAW), gas tungsten arc welding (GTAW) and submerged arc welding (SAW). The SAW process is often preferred because it offers high production rate, high melting efficiency, ease of automation and low operator skill requirement. This review will be very helpful for...

Abstract The study presents a data-driven framework for modelling parameters of hardfacing deposits by GMAW using neural models to estimate the influence process without need creating experimental samples material and detailed measurements. GAS Metal Arc Welding (GMAW) does sometimes create non-homogenous structures in not only deposited material, but also heat-affected zone (HAZ) base material...
