Which welding process is known for high deposition rates and often uses flux or shielding gas?

Explanation:
High deposition rates come from a welding method that can continuously feed filler and shield the weld without slowing down. Flux-cored arc welding uses a wire filled with flux, which provides shielding from inside the wire itself. That lets you weld at higher speeds and deposit more metal per pass than many other processes. Some FCAW setups also use shielding gas (dual-shield), but the key idea is the flux core enabling fast deposition while providing protection from contamination. In comparison, processes that rely on a separate shielding gas with solid wire or on a ceramic-coated electrode tend to have slower deposition rates, or require different setups, so they don’t match the combination of high deposition and flux-based shielding as closely.
