Benardos and Poton invented in 1800 in Russia. After 30 years in 1830 opened the first institute in Ukraine, the name was “Poton”. Such us the first welder students graduated in this institute. This institute was only high education in Europe. And then over 1900 new welding processes invented in USA, France, and Germany. In 1930 USA, France, and Germany scientists invented gas, plasma and LASER welding types. Plasma and LASER welding processes are young welding processes in welding engineering. And there is 30 000-40 000° calcium temperature in plasma welding process. Electricity and gas ions use plasma welding process. It’s very high temperature inside all welding processes.
