I am in the process of analyzing the parts. The cracks were not apparent at time of weld and the unit passed its hydrostatic test, way beyond the operational level. However the failure occurred at the time of initial live testing. I currently have the parts at a lab waiting on chemical...
We have an application where we join a 16ga 304 1.375 od socket elbow to 16 ga wall 1.375 od tube. Both start as seam welded product. They are both supposed to be A269 which has worked fine previously, this is a low pressure heat exchanger, fluid approx 250 deg fh.
Now we have encountered...
That is very interesting. We have been running with the new magnetic encoders for 2 weeks and have not had a reoccurrence of the problem. However in the past we swapped reader heads on the encoder and the problem when away for a while?
Could you provide any more detail re the "end of cut...
We get the all green on the encoder lights. We keep the strips clean. The reader heads were swapped a month ago which releaved the condition for a while but the problem seems to be back on the same axis agian. Also, the "drift" seems really strange. With the machine not moving due the...

Greetings,
We are having the identical issues on our byspeed which were noted by asw04 in the previous thread from Feb 09.
Loss of position while cutting, etc. Bystronic indicates that we need the encoder strips to be upgraded from optical to magnetic. I am not sure I see...
