📌 Power source (DC – electrode positive typically), wire feeder, welding gun, ground clamp, shielding gas cylinder (if applicable).
: An arc welding process that uses a tubular wire electrode with a flux inner core. AWS Designation flux cored arc welding ppt work
: An electric arc is established between the continuously fed wire electrode and the base metal workpiece. 📌 Power source (DC – electrode positive typically),
FCAW is a semi-automatic welding process that uses a special electrode, known as a flux-cored wire, to produce a high-quality weld. The flux-cored wire consists of a metal tube filled with a flux material that produces a shielding gas when heated. This shielding gas protects the arc and molten metal from atmospheric gases, resulting in a clean and strong weld. FCAW is a semi-automatic welding process that uses
Look at Slide 4. When you pull the trigger, the flux inside the wire melts microseconds after the wire skin melts. That timing is critical. If your stick-out is too short, the flux doesn't have time to react, and you get porosity. If your stick-out is too long, the wire overheats before the arc.
