Essay On Welding

What is welding? When did it first come about? How does it work? Welding is a method of creating or repairing metal structures by joining several individual pieces of metals together through various forms of fusion processes. The history of welding dates back to ancient times. The earliest known examples of welding came from the Bronze Age. During the Middle Ages blacksmithing was developed and many items of iron were forged together by hammering. During the 19th century was when welding became to be what we know it to be today. Welding is a process where two or more pieces of metal are fused together by using heat and pressure. In order to gain more knowledge on how to weld a front bumper onto my father’s jeep I will do some research on different techniques of welding as well as get hands on training from a master welder.
Forge welding was the only welding process until the end of the 19th century. Forge welding is where blacksmiths joined metals by heating and pounding them together with a hammer. Arc welding and oxyfuel welding were two of the first
Welding can be performed in a diverse range of locations such as underwater. However, not all forms of welding are the same. Some use gas while others use electric and some use the newest form of laser welding. Depending on the form and thickness of the material you were using would make a difference on the type of welding process you would have to use. Some of the most used welding techniques used are Arc, Electroslag, Flux-Cored, Gas Metal-Arc, Gas Tungsten-Arc, and Metal Inert Gas. Arc welding is popular for industrial, automotive, and farm repair because its equipment is relatively inexpensive and can be made portable. “More welders have learned this process than any other” (Galvery/Marlow 107). “Today there are more than one hundred welding processes recognized by the AWS” (Galvery/Marlow
