Mig Welding

Is a joint made from a mig welder with sheilding gas as strong as a the same joint made with a mig welder with flux core?

 

Without knowing the details of the materials being welded it is impossible to answer this question. All MIG welds will have an an inert gas as apart of the process since MIG = Metal Inert Gas. The addition of a Flux core is required or recommended for some but not welding applications.

Here is a link to Lincoln Electrics site with recommends on when to used Fluxed core wire in the MIG welder.

I actually worded this incorrectly. I apologize.
Mig vs GMAW Lets say we are welding 2 pieces of low carbon steel. Is the joint made by GMAW (flux core) just as strong as one done in MIG (solid wire)? I have heard that flux core can leave inclusions in the welded joint.

 

I am sad to include this;

http://en.wikipedia.org/wiki/Flux-cored_arc_welding

but they have some good info on the subject.

 

OMG no one believes wikipedia.... its a wiki anyone can write in THAAAAT!

 

Depends on what classification of wire you are using. All wires have a classification number.
Example
ESX-G-X-W106xH
E=Electrode,S=Solid(or F for flux cored) , X= Composition,G=Gas Sheilding,X=Type Of Shilding Gas,W=Weld metal,106=Approximate tnsile strength,X=Inpact energy grade number H= hydrogen controlled
