ANSWER A709 Grade 50W steel is a standard specification for structural steel in bridges with weathering capabilities. With a corrosion index of 6.0 or higher, ASTM A709-50W has substantially better atmosphere corrosion resistance than carbon steels even with the addition of copper.(plate) A709 Gr.50 vs A588 - American Welding Society(steel) The A709 Gr 50 is equivalent to A572 Gr 50. The answer is yes you can, unless you are working with a contract requiring otherwise. I normally run D1.5 PQRs with A588/A709-50W so that the test will qualify the lesser grades as well. I would carefully review the A588 MTR to be sure that the material fully meets ALL requirements of A709, because sometimes the documentation has errors and omissions.

Welding is a fabrication process that joins two or more parts by means of high heat, pressure or both. It melts the parts together and allows them to cool, resulting in fusion. Welding is typically used on metals and thermoplastics, but can be used on wood. Filler materials, which are extra pieces of metal, are often used to seal any gaps.(plate) Welding metals of dissimilar strengths - The Fabricator(steel) Unfortunately, welding AR plate to softer or lower-strength steels (usually A36 or A572) brings with it the potential for cracking in the heat-affected zone (HAZ) of the AR plate.
