History of Welding

Summary

The history of welding dates back to 4000 BC, with Egyptians using copper and later advancing to bronze during the Bronze Age. Over time, techniques like forge welding and pressure welding emerged. Major milestones include the creation of the electric arc in the 1800s, oxy-acetylene welding, and the use of welding in WWI. The 20th century saw innovations like spot welding, gamma-ray inspection, and NASA's use of TIG welding for space exploration. Modern welding now includes robotics and advanced technology, revolutionizing the field.
