Does anyone know how the 0.3 factor was arrived at, that is used in table 2.3 of the AWS D1.1 Structural welding code for steel?
This is for fillet weld allowable connection stress and is applied to the nominal tensile strength of the filler metal. Is this an experimentally obtained number? Does it reflect the probable lower strength in the Heat Affected Zone? or some other reasoning? I am familiar with the 0.6 factor usually applied to a parent material tensile strength to obtain shear strength, but not this 0.3 factor. Thanks for any insight.
