So you just do one bead, but make sure you get penetration down to the
lower layer. It really is just an elongated rosette weld.

Well,we're back to attempting to get the lower level molten while not
burning away the upper layer. In the case of the rosette weld, I was
told to make a small hole in the upper layer, aim thru the hole, wait
until the lower layer begins to flow, then add filler, ignoring how
far back the upper layer burns back. I'll go practice. Mike
