← TechnologyWhich consequence results when inadequately drying welding rods?
A)Hydrogen embrittlement weakens the weld✓
B)Arc blow increases during welding
C)Spatter increases weld bead porosity
D)Slag inclusions hinder weld strength
💡 Explanation
Hydrogen embrittlement degrades weld strength when moisture reacts while welding because hydrogen atoms diffuse into the steel. This atomic diffusion accelerates cracking, therefore embrittlement occurs, rather than localized splatter that porosity issues induce.
