E308 rods 2

[LPPE]

Posted in Welding and Bonding forum, but hoping to catch additional fish in this forum.


I'm checking some calcs, and the engineer lists E308-L-16 welds. The calcs list the ultimate capacity as 4.18k/in for a 3/16 fillet weld (or perhaps a flare bevel weld).

I want to check that 4.18 number, and my question is what is Fu of E308? (Using equation P=0.3*Fu*0.707*t for ult. capacity).

Hi LPPE,

Typical min tensile for E308L-16 filler metal is 75 ksi tensile.

Source: ASME Boiler & Pressure Vessel Code 2004 ed, Section II, Part C, SFA-5.4. This is for SMA but others have the same min tensile.

Hope this helps.

The Lincoln Electric publication "The Procedure Handbook of Arc Welding" also states that the minimum tensile strength for AWS Classification for E308L weld metal is 75 KSI (as referenced from the AWS A5.4-69). AWS A5.4-92 also lists the strength at 75 KSI.
