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-
electrode angle incorrect,
rate of travel too high
