CURRENT TOO L OW
Arc
i s difficult to maintain.
Very little penetration. High
bead.
T_AVELTOO FAST
Sman bead undercut in
some p_aces. Rough top
and little penetration.
CUREEHTTOO HIGH
Wide thin head, undercut.
Crater pointed and long,
Rod burns elf very fast.
ARC TOO LONG
Surface ef weld rough.
Rod melts off in globules.
Are makes hissing sound.
TRAm/EL TOO gLOW
Metal piles up, making a
wide heavy bead, over-
tapped at sides in places.
NORMAL CONDtTIONS
Uniform ripples on su_ane
of weld. Arc makes steady
crackling sound.
Figure 9
Practice laying beads approximately one inch apart until
a good we_d can be produced with all the different rod
sizes the welder wilt handle (fig. 7). After becoming pro_
ficlent in running a bead, build up a pad of weld metal
Clean each bead before laying the next and make sure
they are fused together (fig. 8). Run the second layer at
right angles to the first and the third at right angles to the
second, etc.,.until a pad approximately 1/2-inch thick has
been built up. This type of welding _s used to build up
round or flat surfaces or reinforce parts that are rusted thin.
To avoid distortion when building up the end of a shaft,
run the beads paralle! to the axis and lay each successive
bead on the opposite slde as shown by the numbered steps
in figure 10. Cover the entire shaft with weld metal for
the desired length. If the place to be welded is not at the
end of the shaft, weld around it and turn the shaft slowly
to keep the we|d puddle tn the flat position _fig. 11). Clean
off the slag after each bead, then machine the shaft to
proper size.
