← TechnologyWhich outcome occurs when the carbon content exceeds design specifications in welds connecting steel beams?
A)Increased risk of hydrogen embrittlement✓
B)Elevated beam compressive strength
C)Improved weld ductility at low temperatures
D)Decreased yield strength of beam
💡 Explanation
Increased carbon causes martensite formation, undergoing phase transformation during cooling; hydrogen embrittlement occurs due to hydrogen diffusion, concentration, and cracking. Lower carbon rather than increased carbon achieves higher weld ductility; beams compressive stress is related to concrete qualities, not weld carbon content; therefore, hydrogen embrittlement is the answer.
