When welding with a flux cored electrode there are two metal transfer types used! The transfer types are Spray Transfer and Globular.
Spray transfer is the most commonly used. Just like the name states the metal from the electrode gets heated up to the point that it literally
sprays the filler metal to the joint. Globular transfer heats up the electrode hot enough for globs of metal to drip off of the electrode to the weld joint.
What separates the two transfer types are, voltage settings, wire speed, and the gasses used, if any.
Joint preparation for flux core is not as critical as with MIG welding. FCAW can typically burn through mill scale and minor rust. In many cases
when the metal is cut with a torch, it can be welded asis, with no additional cleaning. For the ship building industry this is a huge savings in labor cost.
In addition to easy joint preparation, beveled grove joints can be narrower for metals ½ inch or thinner, and they can be welded in a single pass with full penetration on both sides.
