Mig welding is considered to be the easiest type of welding to learn.
But Mig welding uphill is where things get much harder.
Gravity will try its best to make a vertical uphill weld droop and sag.
And add to that fact the tendency of a welder to lean the gun back as well as hold too long a stickout in order to see the puddle, and you have some problems to overcome.

But there is some good news…
Just pay attention to a few things and vertical uphill welding can work out ok for you. These few things make a lot of difference.Once you get a handle on them, its just practice from there on out.
For this weeks video, I am using 1/4" thick cold rolled steel bar stock.
using 3 pieces about 8 inches long each, I tack weld them so that I have 4 tee joints.
By welding all 4 tee joints and by using multiple passes on each joint, This drill provides a lot of practice and "under the hood" time with very little prep time and very little metal.
You will need to either set up several of these so that there is some cooling time while you alternate between practice joints, or just get a bucket of water to use as a quench bucket so that you can quick cool your piece every 3 beads or so.
A word for beginners who might get the wrong idea about speed cooling metal.
Speed cooling carbon steel is usually not a good idea.
Its never good practice for a welding test or a live production weld.
Carbon steel can harden if it is heated up and then quenched by dunking in a bucket of water.
So while I dont want anyone to get the idea that dunking hot carbon steel into a bucket of water is acceptable practice, it really helps to maximize your "under the helmet" time and so I heartily recommend it as part of learning to weld.
