Welding Processes
A Brief History of Welding
Late 19th Century
Scientists/engineers apply advances in electricity to heat and/or join metals (Le Chatelier, Joule, etc.)
Early 20th Century
Prior to WWI welding was not trusted as a method to join two metals due to crack issues
1930’s and 40’s
Industrial welding gains acceptance and is used extensively in the war effort to build tanks, aircraft, ships, etc.
Modern Welding
the nuclear/space age helps bring welding from an art to a science
