7. Always use MIG plug welds where excessive
metal thickness or limited access make
resistance spot welding impractical. Make plug
welds either by using holes left by the spot weld
cutter, or through holes punched and drilled for
the purpose.
8. Dress all welds using either a sander with 36
grit disc, or a belt-type sander and/or
impregnated wire brush.
NOTE: Brazing operations, if required, must be
carried out at this point.
