Calculate Take-Out and
Butt Weld Elbow Cut Marks
The Take-Out function can be used to quickly
solve a Take-Out and butt weld elbow cut
marks for a known bend angle and Pipe Size.
Find the arc lengths for an odd bend angle of
37° for 12” pipe.
Note:
All Take-Out calculations are based on
Standard type steel pipes. O.D. See the
Cut
Length –
Known Take-Out Value
example
to solve Cut Lengths for known Take-Out
values.

once after entering the welder's gap.
For example, if you keep the fractional
resolution at 1/16, the outputs above for
IARC would be 4 inches, and CARC would
be 6-3/8 inches.
The cut length for the pipe is 35 and 1/4
inches and bend angle is 40.46°. Included
in the outputs are the arc lengths to be used
to cut your butt weld elbow to the calculated
bend angle. These are inner arc length of 4
and 1/32 inches, center arc length of 6 and
11/32 inches, and outer arc length of 8 and
11/16 inches.
