Dear All,
Good Day
We are going to preparing a new WPS/PQR for welding of API 5L X65MS pipeline (sour service). We have below concerns:
1-Hardness less than 250 HV
2-impact test result (ind. > 38J, Ave>45J)
3-SSC resistance in H2S service.
According to Bohler handbook we have selected below combination:
Root & Hot: SMAW-BOHLER FOX BVD RP (8018-G)
Filling & Cap: SMAW-BOHLER FOX BVD 85 (8018-G)
Of course we have an alternative for Root & Hot: GTAW-BOHLER EMK 6 (70S-6)
If you have any experience on above filler metals, please let us have your opinion.
Thx in advance for your kindly response.
