I'n no welder, but the guy who did my notch is, so I'm just regurgitating what he did/told me. He is also an absolute perfectionist... so maybe it's overkill.
He did what was shown in the image 2 posts back. Bevelled all the edges so he had a roughly 3/6" deep 'V' to fill.
He laid the first weld a little cooler as he'd blow through with too much heat since the bevels removed 90* of the material there. For that pass he used a 1/8" 6018 rod. Can't help with amperage (My notches I drew in autocad, and had custom made, so they are 3/16" thick).
His second pass he used 3/16" 7010 rod. again, not sure of the amerage. If you want photos of the notch and the prep before hand, I'm pretty sure we're got at least a handfull of photos I could dig up for you.
The remainder of my truck was/will be done with my MIG which I'm much more proficient with (Again, definitely not a pro).
Prep before the weld should usually be almost as time consuming (or more) than the weld itself. It's all in the prep!
In the end... if you want to know what your welds should not look like, refer to any of the factory welds on your frame
Also just remembered. If you want tips, help, info with regards to your welding, sign up to this forum:
For one, they definitely know their stuff. There is no shortage of super cool builds to browse, and they have one resident minitrucker there who has done some sick builds. Lastly, they are always super eager to help and get a glimpse of your own project they are providing pointers for.
