Unloading – The way a SMAW electrode, typically an AWS 7018 classifiion, burns off while welding. It occurs as a large amount of the SMAW electrode releases across the arc, often resulting in additional spatter. Keeping up with SMAW lingo isn’t critical to
The History of Welding - Welder Portal
The history of joining metals can be dated back to the Bronze and Iron Ages. In the Bronze Age, small gold boxes were made by pressure welding the parts together. In the Iron Age, the Egyptians learned how to weld iron parts together. The Middle Ages brought forge welding and the development of the art of blacksmithing. To create the bonding of metals, blacksmiths then were using the technique

Electric Arc Welding: Meaning, Procedure and Equipments
The arc welding is a fusion welding process in which the heat required to fuse the metal is obtained from an electric arc between the base metal and an electrode. The electric arc is produced when two conductors are touches together and then separated by a small gap of 2 to 4 mm, such that the current continues to flow, through the air.
