Facts About Welding
1. Welding has a history going back thousands of years
In "forge welding", two metal parts are joined by heating them up and then striking them together. This process originated in the Bronze and Iron Ages in both Europe and the Middle East; It could be as early as 3200 BC. to have been used.
2. Modern arc welding
Originated in the early 19th century. Today's modern welding process was created by Sir Humphry Davy in 1800 and by the Russian scientist Vasily Petrov in 1802. These men discovered the continuous arc, which is still used in welding today. In 1881 and 1882, Nikolai Benardos and Stanislaw Olszewski created “carbon arc welding”, the first modern arc welding process, which led to the use of metal electrodes and other advances in the late 19th and early 20th centuries.
3. World War 1 & 2 was decisive for the further development of welding technology.
During World War I, welding was studied by many military powers to determine which methods would give the best results for military machinery and equipment, leading to the first welded ships and airplanes and advancements in bridge building and more. Welding technology continued to advance in the 1920s with the advent of shielding gas. Like World War I, World War II saw many advances in automated soldering, AC power, and soldering fluxes that led to advances in soldering technology. Gas Tungsten Arc Welding (GTAW) was perfected in 1941.
4. Welding is also important for plastics
Welding is not only used to join metal. It can also melt and join plastics and is used in the automotive and electronics industries. Ultrasonic welding is a common technique in plastics: it uses high-frequency sound waves that heat the plastic molecules, forcing them to bond to form a tight, seamless bond.
5. Welding plays an important role
In our daily lives The art of welding is vital in our society and is used in many industries. It is estimated that half of all products require welding as part of the manufacturing process! From cars to buildings to computers, soldering is an integral part of for many of the products we use today.
How important is welding in production? The first robot used in manufacturing was built by General Motors in 1961 to tack weld automobiles using step-by-step instructions built into a large 2-ton magnetic drum attached to the machine.
6. The first industrial robot was developed for welding
7. Welding in space
This was first done by the Russians in 1969. Russian cosmonauts from the Soviet Union welded the first metal in space on Soyuz 6 in 1969 using electron beam welding, plasma arc welding and electric arc welding. They reported that these welds were "as strong" as terrestrial welds.
