Entering the
tube parameters
is tube magnetic ?
set sensor signal
to „leakage flux“
check if signal gets
better with less
magnetization.
yes
yes
no
no
Signal gain = 1
magnetic flux = 100
1. diameter of tube
2. speed resp.
3. rotation rate
4. settling time
5. slippage
6. width of weld seam
7. sort-out threshold
magnetic flux < 100
can weld seam signal
easily be evaluated ?
no
set sensor signal
to „eddy current“
test run in x/y mode
finding the
optimal settings
start test run;
finding the remaining
setting values
1. magnetic flux
2. frequency
3. input gain
4. signal gain
5. phase
6. high-pass and low-pass
1. sample rate per cm
2. filter type
weld seam signal is to run in y direction
fault signal is to run in x direction
optimum found ?
store
yes
store
start test run
