 Hi Brent. To keep it easy, just one MIG weld on the inside, then gouge 
out the top ( mostly just cleaning because MIG  welds made with cover 
gas are clean anyway ) and lay filler beads into the cleaned groove. It 
doesn't hurt to make the first root with TIG, again because the TIG process is 
so clean, and any small defects in the first underside weld will show when using 
the TIG. Frank D. Great Deals on Dell Laptops. Starting at $499.  |
