A History of Welding

Welding has been used for several millennia, with the earliest examples in the bronze and iron ages in Europe and the Middle East. Welding was used in construction as far back as Delhi, India in 310AD. The middle ages brought new advancements in forge welding. Forge welding is when a blacksmith would pound heated metal repeatedly until materials bound together. The welding industry continued to grow through the following centuries.

The short-pulse arc was discovered in 1800 while the continuous electric arc was discovered in 1802. This was significant as a stable arc discharge showed indication of possible uses over many different applications. The first electric arc welding method known as carbon arc welding used carbon electrodes and was created in 1881. Advances continued with the discovery and invention of metal electrodes in the late 1800s. A coated metal electrode was released around 1900 which gave a more stable arc. Alternating current welding wasn’t invented until 1919 but didn’t become popular for a decade after its invention.

Major advances were made in welding technology in the 1920s such as introducing automatic welding in which electrode wire was fed continuously. There were many advancements throughout the decades, but in 1957, the flux-cored arc welding process debuted, and in the same year plasma arc welding was also invented.

Below is a list of the different methods of welding, and what they are known as.

Stick Welding=Shielded metal arc welding

TIG Welding=Gas tungsten arc welding

MIG Welding=Gas metal arc welding

Sub Arc Welding=Submerged arc welding

Depending on the material you are working with will depend on what method of welding you would use. For instance, MIG welding is useful to weld multiple metals such as carbon steel, stainless steel, aluminum, copper, and many more. TIG welding is also versatile and can be used on most of the same materials. Stick welding can be done on stainless steel and nickel-based alloys. There are some material combinations you cannot weld together like aluminum and steel, aluminum and copper, and titanium and steel. When welding materials, it is important to have clean edges for smooth fitments. Utilizing the versatility and reliability of a KAMA bandsaw will help significantly to save time and energy with its clean cuts, every time.
