To MIG weld Kindorf (a type of metal framing often used in construction), start by cleaning the surfaces of the metal to remove any rust, paint, or contaminants. Set up your MIG welder with the appropriate wire and gas settings for the thickness of the material. Position the pieces to be joined and use a steady hand to create a consistent bead along the joint, moving at a moderate speed to ensure good penetration and avoid overheating. Finally, allow the weld to cool naturally and inspect for quality and strength.
Most common and main limitation of MIG welding is that MIG welder could not weld thicker metal. If you want to know details then visit this site.
can weld aluminium with a mig or tig welder
yes
yes
Mig (GMAW) has almost replaced Stick (SMAW) in industry. Small machines can weld thin materials and larger machines weld metals of unlimited thickness. Mig is easy to use and has less waste (no stubs) than stick. Flux core wire produces a slag covering but bare wire w/gas leaves a clean weld.

place the metal clamp on a form of metal turn the mig welder on turn the gas on know were your welding flip your shield down and then give er
mig, oxy-acetelene, arc,
Yes, but, it isn't particularly easy. You should practice on flat stock first.
When you weld steel you need to make sure that oxygen in the air is kept away from the weld while it's being formed. Otherwise the iron in the weld burns in the oxygen and forms a poor weld. Electric welding rods are generally coated with a flux which forms a gaseous shield around the weld point and keeps away the air. Some welding processes (MIG for example - MIG stands for metal inert gas) do not use a flux coating but have an arrangement where argon or CO2 is passed to the weld point to keep the air away in a different way.
MIG is far faster than all other welders, and you can get an aesthetically appealing weld AND good penetration, so its "pretty" and strong
