OPERATION 5-12 0-5461
Description Possible Cause Remedy
4 Portions of the weld run do not fuse
to the surface of the metal or edge of
the joint
A Small electrodes used on
heavy cold plate
A Use larger electrodes and
preheat the plate
B Welding current is too low B Increase welding current
C Wrong electrode angle C Adjust angle so the welding
arc is directed more into the
base metal
D Travel speed of electrode is
too high
D Reduce travel speed of
electrode
E Scale or dirt on joint surface E Clean surface before
welding
Art # A-05867_AC
Lack of
inter-run fusion
Lack of side fusion,
scale dirt, small electrode,
amperage too low
Lack of root fusion
Lack of fusion caused by dirt,
electrode angle incorrect,
rate of travel too high
