Hello everyone, here are the variables and information about the WPS, let me know what you think: 4130 to the same.
1. Base metals: ASTM A-510-06 GRADE 4130 to the same
2. Purpose: For welding the last API flanges on a wellhead
3. filler metals: GTAW (ER80SNi-1)root and hot pass, then Flux Core (E71T-12M) fill and cap
4. Pre-heat: 300 F minimum
5. PWHT: 1250+-25F 1hr/inch of thickness, but not less than 1.5hr
6. Base metal thickness: 0.600"
7. Thickness range qualified: 0.1875" - 1.200"
8. Charpy Impact testing: None (No temperature; service or ambient is anticipated to get below -20F)
9. Position and progression: All and Upwards
10. Additional question: At what temperature and/or thickness do I worry about Charpy Impact testing for this procedures.
Thank you very much for your help!
