last night at work i was being a little lazy so instead of flipping this project i was working on, i figured i would blast it with the mig in the overhead position. Then it went all wrong i noticed at the end of the wire it was doing some sort of dripping effect and the puddle would not hold it's shape.when welding overhead position do you generally weld with less heat and wire?the plate was 1/2" and i was using .045 E71t-1 with 75/25 mix.
Reply:I personally wouldn't try to weld overhead with .045 wire.  To cut back on the wire speed and voltage may help, but you're going to start compromising the joint.  If I had to, I'd try a weave, spreading it out enough until you see the puddle start to teardrop and cool on the trailing edge, so you know it will solidify.
Reply:[QUOTE=Supe]I personally wouldn't try to weld overhead with .045 wire. [QUOTE]Why?  There is absolutely nothing wrong with welding overhead using .045    E71-T1.  You can weld vert up and overhead with wire as big as 5/64.  It is not easy like .045, but it can be done.  My size of choice for vert up and overhead is 1/16.When welding overhead, use the same settings as vert up.  You will get dripping if your gun angle is wrong.  Use a slight drag and don't weave.  Stringer beads are the best for overhead.

Reply:Overhead no problem......... in this pic the lower bead is an overhead fillet 3/4" plate, 1/16" wire. Spray with a forehand motion.... if you are doing a V groove then weldrwomn has already covered it._________________Chris

Reply:increase the wire speed a little & try welding toward the ground.
