FCAW Classifications – American Welding Society, WELDING ELECTRODE CLASSIFICATIONS, FCAW (Flux Core Arc Welding) Definition, Process and Machine, Flux-Cored Electrodes Usability Designators, AWS classifies all flux-cored electrodes into one group for the Flux-Cored Arc Welding (FCAW) process. However, there are two fundamentally different categories or sub-sets of electrodes in this group. These include self-shielded, flux-cored electrodes (FCAW-S process) and gas-shielded, flux-cored electrodes (FCAW-G process).
An example of a carbon steel flux-cored arc welding electrode classification is E70T-4, where: 1. The “E” indicates an electrode. 2. The second digit or “7” indicates the minimum tensile strength in units of 10,000 psi (69 MPa). Table 10-12, below, shows the mechanical property requirements for the various carbon steel electrodes. 3. The third digit or “0” indicates the welding positions.
The Fcaw is a process,in which coalescence is produced by heating with an electric arc between a continuous tubular consumable electrode and work.the electrode is flux-cored, the flux is contained within the electrode which is hollow. In addition to flux mineral and ferroalloys, the core can provide additional protection and composition control.
