Which risk increases when welding near pre-stressed concrete beams?

💡 Explanation

Hydrogen embrittlement occurs because atomic hydrogen from welding diffuses into the high-strength pre-stressing steel, reducing its ductility and fracture resistance. Therefore, structural integrity is threatened, rather than causing concrete degradation or tendon issues.
