Talk:Flux-cored arc welding

Unsupported claim that FCAW is the most effective welding

This is also the strongest and the most effective welding because it make the molecules melt at a differnt temperature because of the flux —Preceding unsigned comment added by 212.248.245.252 (talk) 15:37, 5 November 2007 (UTC)

Question about metal transfer mode

What is the metal transfer used in FCAW Welding Process —Preceding unsigned comment added by 121.7.202.166 (talk) 00:20, 6 June 2009 (UTC) Metal transfer modes are similar to GMAW transfer modes, and include short-circuit, globular, and spray.

FCAW-S does not shield by way of shielding gas

FCAW-S generates insufficient gas to provide signifcant shielding. Instead, high levels of denitriders and deoxiders, such as Al, Ti, Zr, are used to tie up the otherwise detrimental levels of nitrogen and oxygen in the weld pool. Reference Professor Tad Bonisiewski's book on self-shielded flux-cored arc welding. —Preceding unsigned comment added by 69.143.113.243 (talk) 23:40, 12 September 2010 (UTC)

What kind of gas to use with FCAW?

what kind of gas can be used in the process of FCAW? only CO2? —Preceding unsigned comment added by 124.127.98.98 (talk) 01:49, 5 May 2011 (UTC)

Unsupported, probably incorrect, claim that FCAW ingredients produce shielding gas

"this core contains more than just flux, it also contains various ingredients that when exposed to the high temperatures of welding generate a shielding gas for protecting the arc. This type of FCAW is attractive because it is portable and generally has good penetration into the base metal. Also, windy conditions need not be considered."

The article currently makes this claim about the action of the ingredients in the core of the flux-core wire used in FCAW-self-shielding. If someone has a reference for this claim, please add it? My impression is that the main action of flux core is to create a protective slag over the cooling weld metal, and it provides ingredients that deoxidize and denitride. In this I agree with a previous commenter, who mentioned a book by a Professor Tad Bonisiewski, but google didn't find me anything by that name. If indeed the flux produced significant shielding gas, then the later claim that "windy conditions need not be considered" would not be valid. Gwideman (talk) 04:07, 17 June 2018 (UTC)
