In circuit breakers, short-circuit breaking involves extreme conditions linked to the presence of an intense electric arc. This requires the use of specific electrical contacts consisting of a contact tip and its support. SCHNEIDER ELECTRIC uses the resistance sintering technique for the ... Read More
The use of plasmas for the treatment industrial effluents provides a new alternative to the decontamination of wastewater. The strong oxidizing species (O,O3, OH) generated by the plasma, at room temperature, can oxidise organic pollutants present in the water. Our simulation deals with ... Read More
Plasma Arc Welding (PAW) is one of the important arc welding processes commonly used in electronics, medical, automotive and aerospace industries due its high accuracy, finishing, and ability of welding any hard materials. It is an extension of Tungsten Inert Gas welding (TIG or GTAW). ... Read More
Accurate measurement of electrode loads is crucial for the optimal operation of a large 3-phase electric melting furnace. Generally, measurements are made by combining electrode current and voltage drop between the top of the electrodes and the core of the furnace. For this purpose, the ... Read More
Friction stir welding (FSW) is a revolutionary technique for joining high-strength materials, offering superior mechanical properties compared to traditional fusion welding methods. However, achieving optimal surface quality in FSW of Inconel 718 is challenging due to the material's ... Read More
COMSOL Multiphysics® is used to simulate the transport phenomena in arc welding of Nickel to 304SS. Electric Currents (ec) and Magnetic Fields (mf) are used to solve for the Lorentz force which is one of the volume forces. Laminar Flow (spf) is used to simulate flow field. The Lorentz ... Read More
In the development of advanced welding torches, a significant challenge lies in optimizing design and performance while minimizing costs and environmental impact. Traditionally, this has involved extensive physical testing, which is both time-consuming and resource-intensive. To address ... Read More
