3.6.2.1 For welds to be made in the flat position, the arc is carried around the root of the joint and then carried along a spiral path to the center of the hole, fusing ser:-'s and depositing a layer of weld metal in the root and bottom of the joint. The arc is then carried to the periphery of the hole, and the procedure repeated,

,,,.a fusing and depositing successive layers to fill the hole to the depth required. The slag covering the-weld metal should be kept molten, or nearly so, until s

the weld is finished. If the arc is broken, the slag must be allowed to cool and be completely removed

(,,

before re-starting the weld.

~

.x i-3.6.2.2 For welds to be made in the vertical position, the arc is started at the root of the joint, at the lower

}l side of the hole, and carried upward fusing into the face of the inner plate and the side of the hole.

Stop at the top of the hole, clean off the slag and l

repeat on the opposite side. After cleaning the slag

'(

from the weld, other layers should be similarly
