Mechanism of arc welding

In arc welding, the electrical phenomenon of "arc discharge" is utilized. Arc discharge is a kind of gas discharge phenomenon, which is a current generated in the air. A voltage is applied to the two electrodes that are spatially independent of each other, the insulation of the air is broken, and a current is generated between the two electrodes, and strong light and high heat are emitted at the same time. Arc-like light generated at this time is called "arc", and a welding method using arc heat as a heat source is "arc welding". In arc welding, a positive voltage is applied to an electrode (welding rod or welding wire), and a negative voltage is applied to a base material. Thus, an arc is generated from the base material to the electrode. The output current of the arc is about 5 A to 1,000 A, and the output voltage is about 8 to 40V. The temperature of the arc is about 5,000°C to 20,000°C. The melting temperature of iron is about 1,500°C. The base material and the electrode become high temperature, after the fusion of bonding.

Analysis and Application Exploration of Plasma Surfacing

Plasma surfacing is a commonly used welding technology, which uses the high temperature and high energy characteristics of arc plasma to heat the material to a molten state and realize welding. Compared with traditional welding methods, plasma surfacing has the advantages of high weld quality, small heat input and small deformation, so it is widely used in aerospace, automobile manufacturing, electronic equipment manufacturing and other industries.

Measurement and inspection of welding quality

Measurement and inspection after welding are divided into inspection of the surface of the welded portion and inspection of the inside of the welded portion. In the inspection of the welding interior, ultrasonic waves or rays are generally used. The inspection of the welding surface is "magnetic particle inspection (MT)" using magnetic particles and "penetrant inspection (PT)" using special liquids ". In recent years, with the innovation of technology, in the factory automation industry, which has higher requirements for mass production speed and quality, the trend of non-contact detection is becoming more and more intense by using "laser displacement sensor" which can carry out high-speed and high-precision automatic detection online.
