The document defines various welding terms including: - Plug welds which join members using a circular hole that is partially or fully filled with weld metal. Proper technique is to initiate the arc in the center and deposit weld metal in spiral layers. - Slot welds use a similar technique in an elongated hole with minimum spacing between slots of 4 times the width or 2 times the length. - Lap joints overlap members in parallel planes while single-welded lap joints only weld along one member's edge.
