Slag on my shoulder

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: http://img190.imageshack.us/img190/2...agshoulder.jpg Any ideas as to how I can remedy this situation? Thanks, Jon 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. |
