I love 7014, but to get any kind of a vee in there between the two
parts, I find it difficult to get a good solid weld in a short space. I
end up with slag inclusions, or burnthrough, or just slag. Yes, I will
probably do it with .035" E70-S-6 and 75/25 mixed gas. Gives a nice
appearance, but one must do root preparation, or get a cold lap weld.
Steve, if "pretty" is the goal, braze it.
Easy, fast, and the nicest-looking weldment you'll get between any two
pieces of metal. Plenty strong.

My point was that I personally find it difficult to get things "pretty"
when there is only a short run of metal, or basically a spot to weld,
doing it with a rod.
A friend of mine was an inspector on a job we were doing for Banister
(the Alaska Pipeline people) through the Atchafalaya swamp. I asked
Francis what made a good inspector. He said that the average human can
spot 90% of bad welds just on appearance. After that, it gets internal
and complicated. I have found that if a weld looks "pretty", it's most
likely sound, and done with knowledge and skill.
Although, I have said (and offended some people by saying) that I could
teach a chimpanzee to wirefeed in less than a day.
