Mig welding overhead is mostly a matter of getting comfortable. Again, POSITION.
The same settings and techniques that are used for flat and horizontal also work on overhead. But if you typically weld really hot, reducing the wire speed by 10% might help.
If you're just looking to keep things simple, this one MIG technique works for all positions.
By tracing the front leading edge of the puddle, this one single MIG welding technique gets penetration in every position.
Using a push angle vs a pull angle is an argument that shouldn't even exist, but folks continue to argue. Both work.
For spray transfer MIG, pushing is usually best. But for short circuit MIG, both pushing and pulling have their place... and that's a good thing because sometimes you don't have ...
In some industries, a certain look is expected for MIG welds. For example, the motorsports industries has adopted the "MIG like TIG" look.
It involves using settings different from what is normally used for production. Wire speed in particular is usually much lower, which lowers the overall trav...
