The addition of ____ gives FCAW the high level of reliability needed for welding on boilers, pressure vessels, and structural steel.
A) flux
B) small diameter electrodes
C) slags
D) bevels

Question

Quizplus · Accepted Answer

FCAW stands for flux-cored arc welding, and the addition of flux to the wire electrode is what sets FCAW apart from other welding processes. The flux helps protect the weld from atmospheric contaminants, produces a shielding gas to protect the weld, and can also add deoxidizers and other materials to improve the quality and reliability of the weld. This makes FCAW a popular choice for welding on boilers, pressure vessels, and structural steel where high reliability is crucial.
