The History of Welding

Welding has been used for centuries to join metal components together. However, the techniques of welding had significant changes over the years due to advances in technology. In this blog post, we will travel through the history of welding technology.


Early Welding Techniques

The earliest form of welding dates back to the Bronze Age, when gold boxes were assembled using pressure welding. Ancient Egyptians, Greeks, and Romans used forge welding, a process where two pieces of metal were heated and hammered together until joined. This method was later replaced by blacksmithing, a process of heating metal and hammering it into shape.

In the 19th century, oxyfuel welding was developed. This is where a flame produced by mixing oxygen and acetylene gas is used to melt the edges of two metal pieces. These pieces were then fused together. This technique was used to build ships, bridges, and other large structures.


Electric Arc Welding

In 1881, the first electric arc welding process was developed by Nikolai Benardos and Stanisaw Olszewski. They used a carbon electrode to create an electric arc. This method was later improved by Auguste De Meritens in 1889, who used a metal electrode instead of a carbon one.

During the 20th century, several revolutionary arc welding methods were developed, including Submerged Arc Welding (SAW), Gas Metal Arc Welding (GMAW), and Gas Tungsten Arc Welding (GTAW). These techniques allowed moreprecise and efficient welding.


Laser and Electron Beam Welding

In the 1960s, laser welding was developed, which used a high-energy laser beam to melt the metal edges and join them together. This technique was particularly useful for welding thin sheets of metal, and it led to the development of other laser-based techniques such as Laser Beam Welding (LBW), Laser-Hybrid Welding (LHW), and Laser-Gas Welding (LGW).

In the 1950s, electron beam welding was developed, which used a beam of high-speed electrons to melt the metal edges and join them together. This technique was particularly useful for welding metals that are difficult to weld with traditional methods. Electron beam welding was later improved by the development of Plasma Arc Welding (PAW), a process that uses a plasma arc to melt the metal edges and join them together.


Robotic Welding

In the 1970s, robotic welding was developed, which uses computer-controlled robots to perform welding tasks. This technique is particularly useful for welding in hazardous environments, such as nuclear power plants, and in hard-to-reach places. Robotic welding also allows for more precise and efficient welding, as robots can perform the same weld repeatedly with high accuracy.



Welding has come a long way since its early days. Today, there are many welding techniques available, each with its own advantages and disadvantages. With the continued development of technology, we can expect more advances in welding techniques in the years to come.
