I know this is a really stupid question <ducking for cover>. I'm happy for someone to say 'google XXX' or 'search XXX'. I really did try to search google and search this forum. So here goes -- does FCAW-G give more penetration/strength than FCAW-S? AKA, if I had the same equipment and ability to gasless vs dual shield...is there a structural advantage of FCAW-G?

Similar process but diferent capabilities. Each has benefits in a given application while strength is rated by the tensil strength of the wire you choose. (Strength) is also a relative term depending on settings, base metal, and weld orientation.

I have more questions than answers

Thank you Poland. I appreciate the article.
As mentioned in the article, FCAW-S has a more globular weld deposit profile (if it can even be said that way) and FCAW-G has a more spray profile. This is my confusion -- are they saying that FCAW-G is a type a spray transfer or just 'spray like'? I initially read it as 'spray like'. However, assuming that it is spray transfer, when comparing FCAW-S to FCAW-G on thick materials, the advantage of FCAW-G would be the ability to use relatively smaller wire (as compared to self shielded FCAW-S wire for the same sized metal) while allowing for adequate penetration. Is that a good way of understanding it? This is a bit confusing for me.

From that article, why did you decide that the size of the wire was important?medsar wrote:Thank you Poland. I appreciate the article.

Where are you getting the language of "more globular" or "spray like" ?
