Since your coupon is in the 6G position, is there a possibility that your welder is exceeding heat input by 'weaving' during the fill passes?

Subject: [MW:4393] RE: Failure of PQR in All Weld Tensile
| Roji (Guru), U r correct, but I m intrested in UTS & also I got all weld tensile values @ 549 / 567 Mpa in main welding procedure & 545 / 525 Mpa in Partial Repar procedure with the same electrode. Is there any effect of welding at the same position two times while Thru Thk. re-repair. Pl. reply PSP
1. Verify that the Yield stress of the weld metal is more than 80 Mpa than the SMYS of the base material. Check Appendix- C page 167 C302 , where it states that the YS of the metal should be minimum 80 MPA above the SMYS of the base material.
If YS of electrode is not more than the base material then the selection of the electrode is incorrect.
2. Also verify what's the all weld tensile value you have got for the electrode specified in the electrode MTC.
Rdgs Roji
