One of the major applications for submerged arc welding is on
circular welds where the parts are rotated under a fixed head.
These welds can be made on the inside or outside diameter.
Submerged arc welding produces a large molten weld puddle and
molten slag which tends to run. This dictates that on outside
diameters, the electrode should be positioned ahead of the extreme
top, or 12 o'clock position, so that the weld metal will begin to
solidify before it starts the downside slope. This becomes more of
a problem as the diameter of the part being welded gets smaller.
Improper electrode position will increase the possibility of slag
entrapment or a poor weld surface. The angle of the electrode
should also be changed and pointed in the direction of travel of
the rotating part. When the welding is done on the inside
circumference, the electrode should be angled so that it is ahead
of bottom center, or the 6 o'clock position.
