Failure analysis of welds

Joining can be a weak link in the construction or product. Damage phenomena such as fatigue cracks, hydrogen cracks, stress corrosion and galvanic corrosion can occur near welds.

In addition, welds have sometimes a lower resistance against corrosion than the surrounding base material. This can certainly occur in stainless steels. BWI assists companies for finding solutions for these problems through application-focused investigations.

  • Corrosion and failure analysis

    Construction or component failures can have many causes. Such degradation can be the result of corrosion, bad weld design, the use of inappropriate materials or other shortcomings.
    Our objectivity and multidisciplinary expertise ensure the identification of the problem’s true root cause.
