Analysis of the Principle, Applications, Advantages and Disadvantages of Plasma Arc Welding

2025-06-12

Analysis of the Principle, Applications, Advantages and Disadvantages of Plasma Arc Welding Plasma Arc Welding (PAW) is an advanced technology that creates high - temperature plasma by compressing an arc and uses its high energy density to melt metals for welding. This process originated from Gas Tungsten Arc Welding and, after optimization, has been widely applied in industrial fields involving refractory metals and high - precision requirements. The following provides a detailed explanation from aspects such as principle, application scenarios, advantages, and disadvantages. Technical Principle The core of plasma arc welding lies in the arc compression effect. During welding, the arc generated between the tungsten electrode (cathode) and the workpiece (anode) undergoes mechanical compression, thermal contraction, and electromagnetic contraction through a special nozzle to form a plasma arc with a temperature exceeding 30,000°C. The energy density of this high - temperature plasma beam can be more than three times that of a conventional arc, which can instantly melt through the material and form a stable weld. A shielding gas (usually argon or an argon mixture) surrounds the plasma stream to prevent oxidation of the molten pool and ensure welding quality. Appli...
