Quizplus · Accepted Answer

The keyhole method involves moving the electrode in and out of the molten weld pool to maintain the shape of a keyhole as the weld progresses along the joint. This creates a deep penetration weld that is commonly used in industries such as aerospace and automotive. The other options (root gap, open root weld, and multipass) do not involve this specific technique.
