NBIC - alternative Welding Method
NBIC - alternative Welding Method
(OP)
HI All. I am new here. Hope someone can help. In the NBIC, welding method #6 there is a term "controlled fill technique". There is no such welding technique defined anywhere. Does anyone know about this? Where did the term come from? This is not in AWS so it must be a NBIC technique. Did the NBIC just make up the term? Any help would be appreciated.

NBIC specifies the limitations for this technique. According to NBIC-2015,this repair is limited to use of an austenitic, nickel-base filler metal ,F-No. 43 and limited to the following consumables: ERNiCr-3 (Filler Metal 82), ENiCrFe-3 (INCONEL Welding Electrode 182), ENiCrFe-2 (INCO-WELD A), ASME B&PV Code Cases 2733and 2734 (EPRI P87 Filler).
You may find some idea about his technique in his article:

My understanding is this technique is still under development.
Thanks.

EPRI has performed a significant amount of testing and development regarding an "engineered approach" for repair of Grade 91 steels. There are some free publications on this subject.
