Question 1984 Deck Safety

The correct answer is B) fillet welds. Fillet welds are the type of welds used to attach stiffeners to a plate. Fillet welds are triangular in cross-section and are used to join two surfaces that are at an angle, such as a stiffener and a plate. This is the common method for attaching stiffeners to plates in ship construction and repair. The other answer choices are incorrect because: A) Seam welds are used to join two pieces of material in a linear fashion, not to attach stiffeners. C) Plate welds typically refer to the welds used to join individual plates together, not attach stiffeners. D) Butt welds are used to join two pieces of material that are aligned end-to-end, not to attach stiffeners to a plate.
