WELDING PROCESSES

Flux-Cored Arc Welding (FCAW) Adaptation of shielded metal arc welding, to overcome limitations of stick electrodes - two versions Self-shielded FCAW - core includes compounds that produce shielding gases Gas-shielded FCAW - uses externally applied shielding gases Electrode is a continuous consumable tubing (in coils)

Welding Pressure Pipeliners and Piping Systems

Vertical Down vs. Vertical Up Welding Vertical down welding with cellulosic electrodes is normally done with high currents and high travel speeds. Cellulosic electrodes have a thin coating containing a large amount of organic cellulose. When the electrode is burned, the coating forms a protective gas coating for the molten metal.
