Tensile Strenght vs Tensile Stress (of welded specimen)

Helo everyone,

I did the UTM Tensile testing for my standard specimen and got the stress strain table.

As a result i got the Tensile Strength (in Mpa). 

In abaqus i modeled the standard specimen and created the weld like model.

The plastic material properties (material properties of my Electrode E7018) is given to the weld geometry and

UTM results for the standard specimen, and got the same result for the UTM tested with welded specimen.

Am i right, in abaqus i am getting the result as the stress, not the strenght, is the stress value can be used for the strength value.

Please suggest me the suitable papers if any one aware.
