Precautions for welding process of ASTM A588 Grade B steel plate

Corrosion of ASTM A588 Grade B steel plate welding points: the oxidation rate of welding points must be the same as that of other materials, which requires special welding materials and technology.

Ponding corrosion: the weathering steel plate is not stainless steel. If there is ponding in the recess of the ASTM A588 Grade B steel plate, the corrosion rate will become faster, so drainage must be done well.

Salt rich air environment: ASTM A588 Grade B steel plate is more sensitive to salt rich air environment such as Hawaii. In such an environment, the surface protective film may not prevent further oxidation inside.

Fading: the rust layer on the surface of ASTM A588 Grade B steel plate can make the surface of objects near it rusty.
