What is a main advantage of FCAW over GMAW?

Higher deposition rate is the main practical edge of FCAW over GMAW. The flux-cored wire lets you run higher currents and faster wire feed, and you can use larger-diameter wires, all of which push more weld metal into the joint per hour. In many FCAW setups, especially self-shielded types, you can weld thick sections quickly and in less-controlled environments, which boosts productivity. Aesthetics aren’t generally better with FCAW and can even require more cleanup due to slag or spatter, and while FCAW can be simpler in field use (no external gas bottle) that isn’t a universal or definitive advantage, so it isn’t the primary reason people choose FCAW.
