History of Welding
As we all know, welding is the practice of creating and or repairing structures by joining pieces of metal as well as joining plastics by numerous fusion methods. The welding industry keeps growing, but it’s probably good to know where it all started.
Now it’s time to take it back to the ancient times as we can call it the Bronze Age. Some of the first examples of welding were small gold boxes. The gold boxes were made by pressure welding lap joints together. Entering the Iron Age, lead to the Egyptians learning the art of welding (that sentence doesn’t make sense). Many iron tools and weapons came out from this. As the Middle Ages carried on, blacksmiths were born. Blacksmiths were known as specialized workmen who then created numerous types of iron tools. They used hammering technique to produce welds. Until the 19th Century, welding techniques remained the same.
Leading into the 19th Century, welding finally had its’ time. A man by the name of Edmund Davy discovered acetylene. Acetylene was known as the use of open flames, opening this door was key in the welding industry. This allowed the manufacture of intricate equipment’s and metal tools. Soon after that, Sir Humphry Davy invented a battery tool which created an arc between two carbon electrodes. In the late 1800’s, cutting and gas welding was developed.
A Russian scientist by the name of Nikolai Bernardos patented the first electric arc welding process. Not much longer after that American C.L. Coffin released a coated metal electrode. Coated metal electrode is with the use of different materials to what we know today and shielded metal arc welding also known as SMAW. SMAW is known as a simple more versatile way of welding. While all this was growing thermite, resistance and oxyfuel welding were making their mark as well. In the meantime, different resistance welding processes were discovered. These processes were seam welding, projection welding, flash butt welding and spot welding. As the years went on, numerous types of welding came about as in electro slag and electro gas, electron beam, laser, plasma welding and cutting.
It is mind blowing how many different welding processes have been developed throughout the years. Welding is a craft that that will continue to grow and expand. If you are a beginner welder, you have a lot of exciting things to learn! If you’ve been welding for years, there is no stopping you from discovering something new. Keep calm and weld on my friends!
