The shielded metal arc welding is a manual arc welding process which uses a consumable electrode coated in flux to lay the weld. An electric current, either AC or DC, is used to create an electric arc between the coated electrode and metals to be welded. As the weld is laid, the flux coating of the electrode disintegrates, giving off vapors ...

Chemistry of Welding. With welding, no chemical reaction occurs besides the simple heating and cooling of the metal. Chemistry plays a key role in the quality of the weld. Oxygen reacts with molten metal, so metal oxide will form on the metal and weaken the weld if there isn''t some kind of protection method. The methods used to protect the ...
