Question 1983 Deck Safety

The correct answer is A) Tack. Tack welding is not used to permanently attach a stiffener to a plate. Tack welds are small welds used to temporarily hold parts in place during assembly, but they are not intended to provide the full structural integrity required for a permanent joint. Instead, the appropriate welding patterns for permanently attaching a stiffener to a plate would be continuous, staggered intermittent, or chain intermittent welds, as listed in options B, C, and D. These welding patterns provide the necessary strength and integrity to permanently join the stiffener to the plate.
