← ScienceWhich risk increases when capacitive discharge welding has weakened electromagnetic fields?
A)Reduced material weld penetration✓
B)Increased risk of plasma arc
C)Higher risk of electrode erosion
D)Increased risk of arc blow
💡 Explanation
Reduced electromagnetic fields cause less effective *magnetic pinch*, and thus a lower energy density at the weld interface; therefore, there is reduced weld penetration; rather than issues of arc blow which relate more to current steering.
