What are the risks associated with in-service welding?
What is burn-through?
How is the risk of burn-through mitigated?
What are the NDE requirements for in-service welding?
Once the welds are done on the fitting or repair sleeve, there is an NDT hold period, anywhere between 12 to 24 hours, depending on the specific company requirements and thereafter the welds are subjected to MPI testing.
There are purists who support the notion of a hot MPI test on each completed run, but this is generally not applied.
What type of electrodes are used for in-service welding?
One way this is done is to use a low-hydrogen electrode for all in-service welding requirements.
