Synopsis on shielded metal arc welding
The shielded metal arc welding is also known as the manual metal arc welding. A consumable electrode is used in this process. The consumable electrode is coated in flux and is used to lay the weld.
The electric arc is formed between the electrode and the metal to be joined with the help of the current that is supplied from the electric welding machine. The flux coating of the electrode will degenerate and vaporize. This will result is a gas that will protect the area of weld and a slag that will help to join the two metals. This welding process is suitable to be used outdoors.
This welding process is used for cast iron stainless steel as well as welding steel. A welding power supply is provided by this setup that will provide the constant power supply. Also provided with the setup is an electrode holder and a work clamp.
