Multiple Choice

A plug weld is a weld made in an elongated circular hole in one member of a joint fusing that member to another member.

Explanation:
Plug welds are formed by filling a circular hole in one plate with weld metal so that it fuses to the second plate beneath. The key point is the hole is circular, not elongated. An elongated or slot-shaped opening is used for a different weld, known as a slot weld. Therefore the statement misstates the geometry—plug welds involve a circular hole, while a slot weld uses a long, narrow opening. That’s why the assertion is false.
