Development of thermit welding technology

In the late 19th century, the German began to use thermit welding technology. Aluminum was used as reducing agent of iron oxide to make castings and repair castings;

At the beginning of the 20th century, Germany, Britain, the United States and France also began to use thermit welding technology, which is welding on rails;

In the 1950s and 1960s, it has become a relatively common technology, which is mainly used in the wireless welding technology of rail joints;

In 1958, China began to study the thermit welding technology in cathodic protection;

In 1960, the thermit welding technology can be widely used in the welding of rail joints;

In 1966, batch production of thermit flux for rail began in China.

This technology has many advantages: the equipment required is relatively simple, the investment required is relatively small, the welding operation speed is relatively fast, the power demand for the power supply is not very large, and the operation is not very complex. Because of these advantages, thermit welding technology is widely used in the field construction, so the development speed is very fast.
