Yeah you will want to do a weave from one piece to the other pausing briefly to let it fill a bit.

It's hard to explain without being able to show someone, but once you start practicing you'll see. if you go to fast the sides of the weld will be cold lap, if you go to slow obviously it will fall out. When you get the welder set right and figure out travel speed the edges of the weld will flow into the base metal like your vert downs.
