Types of Butt Joint
Now weld the two plates together. Weld from left to
right (if right-handed). Point the electrode down in the
crack between the two plates, keeping the electrode
slightly tilted in the direction of travel. (See Figure
B.7)
Watch the molten metal to be sure it distributes itself
evenly on both edges and in between the plates.
Fillet Joint
When welding fillet joints, it is very important to hold
the electrode at a 45° angle between the two sides, or
the metal will not distribute itself evenly. (See Figure
B.8)
To make it easy to get the 45° angle, it is best to put
the electrode in the holder at a 45° angle, as shown:

Multiple Pass Welds
Make multiple pass horizontal fillets as shown in fig-
ure B.9. Put the first bead in the corner. Hold the
electrode angle needed to deposit the filler beads as
shown putting the final bead against the vertical plate.
Make sure to remove the slag from the weld prior to
making the next pass.
