WELDING OPERATIONS I - OD1651 - LESSON 1/TASK 1
FIGURE 14.
CORRECT ELECTRODE POSITION FOR
WELDS AND PROPER BEAD WELDS.
(2) For bead welding, the electrode should be held at or near a 90
degree angle to the base metal as shown in figure 14, view A. However,
in order to obtain a clearer view of the molten puddle, crater, and
arc, the electrode should be tilted between 5 and 15 degrees toward the
direction of travel as shown in figure 14, view B.
(3) The proper arc length cannot be accurately judged by the eye, but
can be recognized by the sound of the arc.
When bead welding with a
short arc, the typical sharp, crackling sound should be heard all the
time the electrode is in contact and being moved along the surface of
the work.
