What is the reason for a centerline crack in a submerged arc weld bead?
- A.
  Usage of a high manganese filler wire
- B.
  Usage of a damp flux
- C.
  Weld bead is deep and narrow
- D.
  Usage of higher voltage than required
Correct Answer
C. Weld bead is deep and narrow
Explanation
A centerline crack in a submerged arc weld bead can occur when the weld bead is deep and narrow. This is because the deep and narrow shape of the weld bead creates a high stress concentration in the centerline, making it more susceptible to cracking. The stress concentration is caused by the uneven distribution of heat and the rapid cooling of the weld bead. This type of crack is common in submerged arc welding and can be prevented by adjusting the welding parameters to create a wider and shallower weld bead.
