I've brazed the wing to scuttle gap up before for someone who wanted a smooth joint between the two. It's took a couple rods each side but did a lovely job of smoothing the seam. The big plus of brazing rather than welding was that if the wing ever needed replacing you could just melt the braze out of the joint. 

 

One down side is the heat, although you can control it to avoid distorting anything it will take off paint within 2-3 inches. I found a paint gun with a long nozzle and a bit or wax oil inside the scuttle void  was required after wards. 

The other downside of brazing is that it can crack over time.

should be welded on the underside, and seam sealer just tidies the job

They sometimes came out of the factory brazed, in the days when the press tools were in good condition and the joints fitted properly. The top of the A panel was also brazed to the scuttle.

Properly done, braze is ok, but protect it from electrolytic corrosion and don't let the MOT tester see it. Bronze weld, on the other hand, is also good, and stronger than braze, but the cost of a spool of MIG bronze is horrendous.

Last one I did was welded underneath and a spot of MIG between A panel and scuttle, as it had come out of the factory that way.

There are several satisfactory ways of doing it.
