Welding, as a method of joining metals, has a history stretching back thousands of years. Early forms of welding date back to the Bronze Age and Iron Age.

Early History:

• Bronze and Iron Ages: The earliest examples of welding come from the Bronze and Iron Ages. Pressure welding, where metals are heated and hammered together, was used to create items like gold boxes and tools.
• Middle Ages: During the Middle Ages, blacksmiths and other metalworkers continued to use forge welding to create tools, weapons, and armor. This involved heating the metals in a forge and then hammering them together.

19th Century Developments:

• Arc Welding: The 19th century saw significant advancements in welding technology. Sir Humphry Davy developed the first arc welding system in the early 1800s, using an electric arc to generate heat.
• Resistance Welding: Elihu Thomson invented resistance welding in 1885. This process involves passing an electric current through the metals to be joined, generating heat at the joint.

20th Century Innovations:

• Shielded Metal Arc Welding (SMAW): Developed in the early 20th century, SMAW, also known as stick welding, became a widely used process due to its simplicity and versatility.
• Gas Metal Arc Welding (GMAW) and Gas Tungsten Arc Welding (GTAW): GMAW (MIG) and GTAW (TIG) were developed in the mid-20th century. These processes use shielding gases to protect the weld from atmospheric contamination, resulting in higher quality welds.
• Laser Beam Welding and Electron Beam Welding: These advanced welding techniques were developed in the latter half of the 20th century. They use highly focused beams of energy to create precise and deep welds.

Modern Welding:

• Automation: Modern welding processes often incorporate automation and robotics to improve efficiency and consistency.
• Computer Control: Computer-controlled welding systems allow for precise control of welding parameters, resulting in high-quality welds.
• Diverse Applications: Welding is now used in a wide range of industries, from manufacturing and construction to aerospace and automotive.
