    innershield is a cored wire with flux in the core. The flux shields the weld pool. It has good penetration and your able to weld outdoors in windy conditions where your shielding gas would get blown away.
    Welders do it hotter!!

    Is that similar to mig welding?

    Default Let's Clarify the Terminology for Wire Feed Welding

    No......It's not.

    If you guys want to be part of a proper "professional" welding site, interact with professional tradespeople, and think of yourelves as "welders" then you should start using the proper terminology. I know I am going to catch some flack for this but that is OK by me.

    Mig (Metal Inert Gas) is an old term that is no longer used....It has been replaced with GMAW (Gas-shielded Metal Arc Welding)

    Flux Core is FCAW (Flux Core Arc Welding) and can be self shield or dual shield.

    Self shield is the wire already described that is "gasless"

    Dual shield requires the presence of an additional inert gas just like is required by GMAW. If you try to weld dual shield wire without the shielding gas, you will have porosity and make a mess.

    I am well aware that it is very common to refer to any form of wire feed welding as "Mig".....but it is inaccurate and improper, so it's about time everyone makes the effort to get it correct.

    Thank you.

    Hopefully the members will take my post the way I meant it to be......The owner's of this site want us - the professional tradespeople, to interact with the hobbiests and newcomers......No problem on my end..... but as the professionals, we should be more diligent in educating these individuals in the proper terminology as a starting point to their "Online Education" for lack of a better term.

    Default mig

    have my 3 G cert, the job posted was inner shield welding and I know the structure is galvinized. I wasn't sure that's what they wanted, A mig welder for that. It usually call's for standard 7018 stick for structure. They have to heaty it also outside when it's cold like this time of year or the inspector will fail it! thank's for your input.mjz ironworker.
