Welding is the process of joining two pieces of metal together by heating their surfaces to the point that they melt. Once the surfaces cool, the two pieces fuse together in a chemical bond. The method has been used to fabricate metal for thousands of years. This guide offers a look at the history of welding and some of the important developments that have occurred since the Bronze Age.

How Did the Welding Process Develop Over Time?

Origins

Historians believe the ancient Egyptians developed welding about 6,000 years ago. The first welded artifacts were made of copper, though other welded metals—like bronze, silver, and gold—appeared in archeological records over the next 1,000 years. Welded items were used in jewelry, clothing, tools, and even armor. By about 3,000 B.C., Egypt had started using charcoal to generate enough heat to weld iron.

Middle Ages

Few technological developments in welding occurred for thousands of years. During the Middle Ages, blacksmiths used forge welding—a combination of high temperature and pressure. 

They'd heat metal in a forge and stoke the flames with oxygen from a pair of bellows. Then, they would pound the two pieces of metal until their molecules bonded together. The hammering process helped the metals meld together while shaping them into the desired final product.

Modern Day

During the 19th Century, welders began using acetylene gas—a colorless, flammable gas—to create the necessary heat to turn metal molten. By the 20th Century, numerous developments were in store. The harnessing of electricity permitted the creation of arc welders. This method utilizes an electric arc that heats metal to its melting point. More recently, welders have used friction and pressure to create the necessary heat, as well as laser technology.
