In case of plain carbon steel, butt welded joints are used for shell plate thickness ≤ _____________ cms?
Correct answer: C. 3.8
- A. 1.2
- B. 0.5
- C. 3.8
- D. 6.8
Explanation
For plain carbon-steel shells, butt-welded construction is used for plate thicknesses up to about 3.8 cm, or 38 mm. The smaller values are not the usual upper limit for this construction rule.
