Condition: Welding a tee-joint with square tubing, 2.5" x 0.188
Electrode: 1/8" 7018AC @ ~125A
Position: Horizontal
So I'm trying to figure out how to finish up the shoulder welds on this
square tubing. What I am doing (after I put fillets on the flat corners),
is to run a stringer to build up the shoulder on the bottom piece, chip off
the slag, then come along and weld the top piece to the stringer.
Unfortunately, the buildup on the shoulder leaves slag between the weld and
the bottom edge of the top piece, that even a cup brush won't reach, as you
can see in the following image:

Any ideas as to how I can remedy this situation?
Thanks,

Looks like the slag is inaccessible because it's under the edge of the
joining piece. Instead of starting with a shoulder, weld that crack
shut first and then build it up.
