Quizplus · Accepted Answer

The projection-weld symbol and the spot-weld symbol may look similar, but they are differentiated by the notation placed in the tail of the arrow. The projection-weld symbol includes a perpendicular line intersecting the arrow, which indicates a projection-welding process. Meanwhile, the spot-weld symbol has no such line but rather includes an "R" notation, which indicates a resistance welding process. Therefore, the best choice is B, which pertains to resistance welding process.
