Arc discharge is a form of electrical breakdown of a gas that produces a sustained electrical discharge, characterized by a luminous plasma arc between two electrodes. This phenomenon is utilized in various applications such as welding, lighting, and plasma cutting due to its ability to generate intense heat and light.

Electrical breakdown is a phenomenon where an insulating material becomes conductive due to the application of a sufficiently high voltage, leading to a sudden increase in current. This process can result in permanent damage to the material and is critical in designing electrical systems to ensure safety and reliability.

Applications of arc discharge

Welding is a fabrication process that joins materials, usually metals or thermoplastics, by causing coalescence through high heat and sometimes pressure. It is a critical technique in manufacturing and construction, offering strong, permanent bonds that are essential for structural integrity.

Lighting is the deliberate use of light to achieve practical or aesthetic effects, influencing mood, visibility, and perception of space. It encompasses various sources, techniques, and technologies to enhance functionality and ambiance in environments ranging from residential to commercial and theatrical settings.

Plasma cutting is a process that uses a high-velocity jet of ionized gas, or plasma, to cut through electrically conductive materials, such as steel, aluminum, brass, and copper. It is favored for its speed, precision, and ability to cut complex shapes with minimal heat distortion.
