Evolution Of Arc Welding
Approximately in 1900, a British inventor named Strohmenger introduced a coated metal electrode, which significantly improved the stability of the welding arc. This innovation was a step forward in enhancing the reliability and precision of welding operations.
During the period between 1907 and 1914, Swedish inventor Oscar Kjellberg revolutionized welding by inventing a covered or coated electrode. This invention marked a significant turning point in the history of welding, as Kjellberg’s coated electrode improved the stability of the arc, increased weld quality, and made the process more accessible.
Parallel to these advancements, various resistance welding processes such as spot welding, seam welding, projection welding, and flash butt welding were developed. Each of these techniques provided unique solutions for welding different types of joints.
Introduction Of Coated Electrodes And Gas Metal Arc Welding
In 1903, German inventor Goldschmidt made a significant contribution to the field of welding with the invention of thermite welding. This groundbreaking process involved using a chemical reaction to generate the necessary heat for joining metals. Despite the requirement for careful handling and controlled conditions, thermite welding marked a major advancement in the field at that time.
During World War II, another welding technique called gas tungsten arc welding (GTAW), later known as Heliarc welding, gained prominence in 1941. GTAW was especially important for welding non-ferrous metals, stainless steel, and aluminum, as these materials were in high demand during the war.
The year 1948 marked the beginning of a new era in welding with the introduction of gas metal arc welding (GMAW). This technique revolutionized the process by utilizing a continuously fed electrode wire, offering a more efficient and versatile method of welding. GMAW, also known as MIG welding, enabled faster and more cost-effective welding in various industrial applications.

Advancements In Welding Technology
Over the years, significant advancements in welding technology have emerged, enhancing the capabilities and efficiency of welding processes. In 1953, welding with consumable electrodes in a carbon dioxide gas atmosphere became popular due to its cost-effectiveness and ability to produce high-quality welds.
In the late 1950s and early 1960s, various variations of gas metal arc welding were introduced, including short-circuiting transfer, globular transfer, and spray transfer. These variations provided welders with more options to suit different requirements and materials.
The 1950s also witnessed the introduction of the electroslag welding process, announced by the Soviets in 1958 and perfected by the Paton Institute Laboratory in Ukraine and the Welding Research Laboratory in Czechoslovakia. This method involved using a consumable electrode and a flux to create a molten slag, allowing for high-quality welds in a relatively quick timeframe.
Additional welding techniques have since emerged, including electron beam welding, which originated in France. It utilizes a focused beam of electrons in a vacuum chamber and has found applications in the automotive and aircraft engine industries in the United States.
Friction welding is another specialized process that uses rotational speed and upset pressure to create friction heat, enabling the welding of various challenging-to-join materials using traditional welding methods.
Furthermore, laser welding, initially developed by Bell Telephone Laboratories, has revolutionized the industry. It utilizes a highly focused and intense beam of light to heat and join metals and nonmetals. This technique has found widespread applications in automotive metalworking operations, providing greater precision and reducing heat-affected zones.
In conclusion, the history of welding spans from ancient techniques employed during the Bronze Age to the modern innovations that continue to shape the industry today. From the early use of heat and hammering to the discovery of arc welding and the emergence of techniques such as coated electrodes, gas metal arc welding, and laser welding, welding has gone through remarkable advancements over the centuries.
