Q: How to flux core Weld basics?

A: Unplug the welder,but keep your safety equipment on. Using a slag chipping hammer,chip all of the slag off of the weld. … Brush the weld with a nylon wire brush to get the little bits of slag out. Inspect the weld. … If you like,you can paint the finished weld once it is cleaned. …

Q: Why does flux core wire Weld thicker metal than MIG?

A: The difference between MIG and Flux-core is the electrode used and they way the melted metal is shielded from the atmosphere. In flux core welding the filler wire is filled with flux. In MIG a shielding gas is used. In FCAW the flux shields and coats the weld pool. The weld then cools slowly creating a very strong weld.
