Preliminary Welding Procedure Specification
Preliminary Welding Procedure Specification
(OP)
Hi everyone.
When I supply pWPS to Contractor for review. He write comment in my pWPS that : due to hardness consideration Contractor advise to use an E 8016 - XX electrode instead of E 9016-G. I don't know why. Hereafter is parameter of pWPS:
+Base metal API 5L X65
+Process GTAW+SMAW
+Root: A5.28 ER80S-G
+Hot: A5.28 ER80S-G
+Third: A5.5 E 9016-G
+Cap: A5.5 E 9016-G
Could Someone explain to me why?
Thanks.

E9016-G electrodes are common in Japan. They have chemistry just out of and sometimes within the range of electrode class E8018-C3 or other AWS specific classes. Many of the Kobelco "G" rated filler metals similarly mimic AWS Class electrodes; the key to their use is the trade designation, which defines the chemistry.
E8010-G and E9010-G fillers provided for decades by Lincoln for welding of pipelines similarly do not fit standard AWS Classes. Again the trade designation provides the chemistry and mechanical properties.
