I tried to weld some corners today. Two things were apparent.
- Welds inside corners were awful. No good fusion. I used 6013 and will try more today, maybe with 7018.
- Welds on outside of corners were great. Nice looking beads, good fusion and they survived a destructive test. I cut out a piece from the resulting angle and beat it with a hammer until it flattened. It did not break.
So, what I am wondering is whether welding inside corners is a good idea if one can do an outside weld. Obviously, it would not apply to situations like T joints.
