In an arc welding process, welding speed is doubled. Assuming all other process parameters to be constant, the cross sectional area of the weld bead will
-
- increase by 25%
- increase by 50%
- reduce by 25%
- reduce by 50%
Correct Option: D
If welding speed is doubled then original cross sectional area would become half if volume remains constant. Therefore, area reduces by 50%.
