When was welding discovered?

Welding has ancient origins, with evidence of its practice dating back to around 3000 BC in Mesopotamia, where blacksmiths used techniques like forge welding to join metals. However, the modern process of welding as we know it began to take shape in the 19th century, particularly with the invention of electric arc welding in the 1880s. The development of various welding techniques continued throughout the 20th century, significantly advancing industrial manufacturing.
