Final answer:
The welding process prone to 'flux breakage' is SMAW (Shielded Metal Arc Welding), commonly known as stick welding, where the coating on the electrode can chip or break.
Step-by-step explanation:
The welding process that uses electrodes that can suffer from "flux breakage" is e) SMAW (Shielded Metal Arc Welding). This type of welding is also commonly referred to as stick welding. During the SMAW process, the electrode is coated with a protective flux, which can sometimes chip or break off—referred to as "flux breakage." This can contribute to defects in the weld, such as porosity or inclusions. Unlike SMAW, the other processes listed, such as EB (Electron Beam), FCAW (Flux-Cored Arc Welding, either self-shielded or gas-shielded), and PAW (Plasma Arc Welding), utilize different methods and materials that are less prone to this specific issue.
