Development History Of Welding

- Aug 30, 2017-

By the end of 19th century, the only welding process was the blacksmith's hundreds of-year metal Forge. The earliest modern welding technology appeared at the end of 19th century, first arc welding and oxygen gas welding, and later the Resistance welding appeared.

In the early 20th century, in the First World War and the Second World War, the demand for military equipment was great, and the corresponding inexpensive and reliable metal connection technology was paid attention to, which promoted the development of welding technology. After the war, several modern welding technologies emerged, including the most popular manual arc welding, as well as automatic or semi-automatic welding technology such as arc welding, submerged arc welding (submerged arc welding), Flux cored wire arc welding and electroslag welding.

In the 20th century century, welding technology developed rapidly, laser welding and electron beam welding were developed. Today, welding robot has been widely used in industrial production. Researchers are still studying the nature of the weld, continue to develop new welding methods, and further improve the quality of welding.

The history of metal connections dates back more than thousands of years, when early welding techniques were found in the Bronze Age and iron ages in Europe and the Middle East. Thousands of years ago, the two rivers of Babylon civilization has begun to use soft brazing technology. In the 340 BC, welding technology was used when manufacturing the iron pillars of the ancient Indian Delhi, weighing up to 5.4 tonnes.
