Default cut pipes to weld a "T"

Another old fashioned way is to use something fairly stiff as some
heavy gasket material to hold on the pipe in what you think is the
right shape and mark it with soapstone. Cut with oxy/acet, see how
much you missed it by and mark again using the guide. A piece of four
or six inch wide flat belt a couple of feet long would work real well.

With six inch dia pipe, the deepest part ought to be 3 inches in from
a straight cut end.

The real old-fashioned way, Karl, is to clamp the pipes in a T and
use a long piece of soapstone to scribe one off the other, then
cut it, clean up the cut, reclamp, and scribe the other off the
first, then make that cut, clean up, fit and weld. I've seen
shipyard pipefitters do that hundreds of times.
