SMAW is the oldest and simplest arc welding process. Shielded metal arc welding (SMAW) uses a consumable, flux-coated electrode to create an electric arc between the electrode and the work piece.
Gas metal arc welding (GMAW) is a common welding process that employs the use of an electric arc formed between the wire electrode and the metal.
FLUX CORED WIRES
Flux cored arc welding just like the name implies, has a hollow wire with flux in the centre and is a highly popular semi-automatic welding process with its unique set of advantages.
S.A.W. WIRE & FLUX
Submerged arc welding is a process in which the joining of metals is produced by heating with an arc or arcs between a bare metal electrode or electrodes and the work.
