![]() The transition to practical application took place at the end of the 19th century. After that, scientists around the world, including such well-known names as Michael Faraday of Great Britain, conducted various electric arc experiments, which for decades were limited to theoretical studies. In 1802, the Russian physicist and electrical technician Vasily Petrov was the first to put forward the idea that the high temperatures produced by an electric arc could be used to melt metals. When did electric metal welding appear?Īt the turn of the 18th and 19th centuries, the electric arc was discovered, and studies of its practical application started. ![]() Such connections were neither strong nor reliable.īut with steel increasingly finding its way into different areas of life and the economy, scientists and technologists faced more and more theoretical and practical questions about metal processing and joining.Īnd the result was a new method of joining metal products! What is metal welding? In this process, parts are joined together by inter-atomic bonds through heating and plastic deformation. After that, the craftsmen waited for the structure to solidify. Foundry welding was also used: the parts to be joined were immersed in molten metal. This was overcome using physical strength and one of the few metal working processes known at the time: forging (cold and high-temperature hammering). But because of many technological limitations, the process was flawed. This made it possible to increase their size, create complex shapes and rectify casting defects. Since time immemorial, mankind has tried to join together fragments of metal articles and metal ingots of natural origin. What is Paton’s role in the global evolution of electric welding, and what is metal welding? This engineering wonder was designed under the direct guidance of the outstanding scientist Evgeny Paton, whose name was given to the bridge that is now used by the residents of Ukraine’s capital city. ![]() For the first time in the history of engineering construction, all its welds were made by means of automatic welding. The construction of one of them started in 1940 and lasted until 1953.Īt the time of its construction, it was the largest all-welded bridge in Europe. There are five active road bridges in Kyiv today that connect the banks of the country’s largest river, the Dnipro. ![]()
