The ancient Greek historian Herodotus states in The Histories of the 5th century BC that Glaucus of Chios "was the man who single-handedly invented iron welding". [6] Forge welding was used in the construction of the Iron pillar of Delhi, erected in Delhi, India about 310 AD and weighing 5.4 metric tons. [7] Forge welding in 1904 [8]
During the middle of the century, many new welding methods were invented. Submerged arc welding was invented in 1930 and continues to be popular today. In 1932, a Russian, Konstantin Khrenov successfully implemented the first underwater electric arc welding.
A modern underwater welding. Khrenov dedicated his entire career to the development of welding techniques and equipment. He invented methods of electric welding and cutting metals under water, designed power sources for arc and spot welding, ceramic fluxes, electrode coatings, methods of cold pressure welding, diffusion welding, plasma cutting and many others.

During the early 20th century, before the development and availability of coated arc welding electrodes in the late 1920s that were capable of making sound welds in steel, oxy-acetylene welding was the only process capable of making welds of exceptionally high quality in virtually all metals in commercial use at the time.
Nikolay Gavrilovich Slavyanov (Russian: Никола́й Гаври́лович Славя́нов; 5 May [O.S. 23 April] 1854 – 17 October [O.S. 5 October] 1897) was an inventor from the Russian Empire who in 1888 introduced arc welding with consumable metal electrodes, or shielded metal arc welding, the second historical arc welding method after carbon arc welding invented earlier by ...
It was not until the 1880s that the technology became developed with the aim of industrial usage. At first, carbon electrodes were used in carbon arc welding. By 1890, metal electrodes had been invented by Nikolay Slavyanov and C. L. Coffin. In 1920, an early predecessor of GMAW was invented by P. O. Nobel of General Electric. It used direct ...
1974: The lithium-ion battery is invented by M. Stanley Whittingham, and further developed in the 1980s and 1990s by John B. Goodenough, Rachid Yazami and Akira Yoshino. It has impacted modern consumer electronics and electric vehicles. [507] 1974: The Rubik's cube is invented by Ernő Rubik which went on to be the best selling puzzle ever. [508]
Welding is the joining of the same or similar kind of metal. Blacksmith, 1606. A modern blacksmith has a range of options and tools to accomplish this. The basic types of welding commonly employed in a modern workshop include traditional forge welding as well as modern methods, including oxyacetylene and arc welding.
