Test plate tensile testing problem

I would like to ask fellow sailors: For the welding test plates of the S30408 product, the elongation after tensile testing was 34.5. Are these test plates considered qualified? Should the elongation after fracture of the welding test plate be greater than that of the base material (steel plate)? What is the reason for it being smaller than the base material?

Does the transverse tensile test not take into account the elongation after fracture?

According to 47016, the test plate is qualified. Neither the weld evaluation specimens nor the product welding specimens take the elongation value into account. There are many reasons why the elongation is lower than that of the base material; welding current, voltage, wire energy, and the type of filler metal can all have an impact.
