FCAW

Flux-cored arc welding (FCAW) is a welding process that uses a continuous solid wire electrode that is flux cored. It can achieve high deposition rates and deeper penetration compared to shielded metal arc welding. FCAW provides high-quality welds and requires less surface preparation than gas metal arc welding. However, it produces more smoke and fumes than GMAW and SAW. The slag also needs to be removed and it causes more spatter. FCAW equipment and wire are also more expensive than SMAW.
