(FCAW) Flux Cored Arc Welding

Flux cored arc welding (FCAW) is a welding process that uses the heat produced by an arc generated between a continuous tubular filler metal (electrode) and the work piece. The filler metal is hollow with flux at the core. Flux present at the core of the filler metal shields the molten weld pool from atmospheric contamination. Flux Cored Arc Welding are mainly of two types: Self-Shielded (FCAW – S) Gas….

GMAW (MIG Welding) electrode specification

GMAW (MIG welding) electrodes are designated by some letters and numbers such as ER70S-6, ER90S-6 and E308L etc. I will explain the meaning of these symbols: FOR CARBON STEEL OR MILD STEEL (SUCH AS ER70S-6 OR ER70S-3) Where, ER – Designates electrode or filler rod XX – Designates the minimum tensile strength of the deposited weld metal S – Stands for solid wire Y – Designates the chemical composition of….
