Thread: Flux or MIG welding?

Which has a stronger weld?

i know that flux is better for thicker steal but i cant find out which one is stronger.

thanks

It's the welder amperage that determines it's welding capacity, I don't care much for flux weld. Gas shielded (Mig) is a cleaner weld. Usually the larger welders are gas shielded Mig. The less expensive welders are more commonly the flux core welders (Less equipment needed). If you want a real clean weld try TIG.

i just got a MIG/Flux its 90 amps max not a real big one but i dont feel like hooking up gas to it so im rolly just gonna use the flux wire.

ill be welding roll cage tubes(not the outer shell just cross bars)and frame components would that be sufficent enough to do that stuff

Assuming the same wire type, ie mild steel, I don't believe either is stronger. But either has specific usages and limitations.
It really depends on the material being welded and conditions.

Here's a decent overview -

I believe for roll cage frames flux-core is better.
What pipe material are you using?

I would try a 90 degree butt weld and check for penetration.
You don't want all the metal on the outside. Some should penetrate to the inside of the fitting.

Be sure to observe the duty cycle for your welding machine.
They are easy to burn up.

steal pipe 1 3/4 about 2/16ths thick

Mig welding looks nicer when you have a rust free piece of metal, flux welding will work better if the metal is rusted. Carlg

well thats what im using then cuz i got alot of stuff that is rusted

the weld looks clean but only if your good at it

never heard that one before.

well barrett you better get good then anyways hes not talking about how you weld hes talking about splatter

you cant keep the flux-core from apattering. useing argon to weld with is cleaner.

yeah i dont really care about the spatter were not making chopper gas tanks hah ahah

tig tig i have a new 250 miller i have not use no more that five times in three years it is a great welder but my 275 lincoln tig .thin or thick it dose not matter steel or alumium. a tig is a wise investment no sparks fly on stuff no big holes burned in you no hot sparks burning the ear wax out prep work is the start of a good weld buy cup wheel for a angle grinder the nice thing about a tig is you add the rod as needed and i have a thum wheel on the torch you can turn heat up or down when welding i use my tig all the time i would think about a tig

yeah i know wut your saying and we were thinking about it but thats not really wut we need right now

they have real strong welds thats really nice

Yes S10, you have to grind the metal down and make sure its real clean to get your best weld with a mig welder.Flux welding is more forgiving with a less than perfectly clean surface .
