Which critical issue arises when high-strength steel beams experience Hydrogen Embrittlement near welded joints?

💡 Explanation

When high-strength steel beams undergo Hydrogen Embrittlement (HE) near welds, atomic hydrogen diffuses into the steel lattice because welding introduces residual stresses and high temperatures, reducing ductility, ultimately leading to brittle fracture. Therefore, reduced ductility results, rather than increased yielding, enhanced corrosion resistance, or improved fatigue life, which need different chemical/mechanical changes.
