    selective weld seam corrosion

    Metalguy, I am sure the corrosion is in the seam. The vicinity surrounding the seam has some pitting and general corrosion but it is outside the HAZ. Metallographic examination revealed a weld seam that appears to be almost all ferrite. The ferrite in the seam is needle shaped and, no, it does...

    weld seam corrosion

    I have recently encountered a problem with weld seam corrosion. I read that the ferrite enriched-zone is more susceptible to corrosion but I really don't understand why and I would like to. Does it have something to do with the low carbon content in ferrite?

    selective weld seam corrosion

    No it is not a SS. It is a low-carbon steel. The weld seam appears to be acicular ferrite. Extensive corrosion took place almost exclusively at the seam. I read this happens at times and is due to the acicular ferrite. I am new to this field and I don't really understand what makes the ferrite...

    selective weld seam corrosion

    No I am not a student. I have recently encountered a problem with weld seam corrosion. I read that the ferrite enriched-zone is more susceptible to corrosion but I really don't understand why and I would like to. Does it have something to do with the low carbon content in ferrite?

    selective weld seam corrosion

    What is the mechanism behind selective weld seam corrosion? In a low-carbon steel, why is a ferrite-enriched zone more susceptible to corrosion? Is acicular ferrite more susceptible than ferrite, if so, why?
