Life is made of ever so many partings WELDED together.

— Charles Dickens

Shielded Metal Arc Welding, otherwise known as manual metal arc welding or flux shielded arc welding, is a process that uses a flux-coated electrode to form the weld. As electricity passes through the electrode, the flux forms a gas, which shields the electric arc in the space between the electrode and the metal being welded, preventing contamination from atmospheric gasses in the weld. This process is fairly simple and doesn’t require much in the way of specialized equipment, making it very popular.
