← TechnologyWhich failure risk substantially increases when welding transverse stiffeners incorrectly onto a steel beam's tension flange?
A)Lamellar tearing within steel✓
B)Reduced thermal conductivity
C)Increased buckling resistance
D)Enhanced fatigue endurance
💡 Explanation
Incorrect welding introduces high, localized residual stresses, because the heat-affected zone undergoes constrained contraction during cooling, triggering potential for lamellar tearing rather than enhanced strength; therefore, tearing risk rises, while improved conductivity is unrelated.
