Introduction
Shielded Metal Arc Welding (SMAW) is a welding process that uses an electric arc and coated electrodes to join metals. It is portable, simple, and commonly used in industries.
SMAW on Aluminium
Aluminium is lightweight, corrosion resistant, and conducts heat quickly. SMAW on aluminium requires special electrodes and clean surfaces.
SMAW on Cast Iron
Cast iron contains high carbon and is brittle, so it cracks easily during welding.
SMAW on Stainless Steel
Stainless steel is strong and resistant to rust and corrosion.
