← TechnologyWhich consequence results when welding thick high-carbon steel plates?
A)Hydrogen embrittlement weakens the weld✓
B)Increased corrosion due to galvanic action
C)Creep deformation at lower stresses
D)Increased damping capacity of structure
💡 Explanation
Hydrogen embrittlement leads to cracking because hydrogen diffusion into the weld microstructure reduces ductility, therefore causing brittle fracture rather than creep or increased damping; controlled heat input mitigates this risk.
