Figure 7-36.Bead welding in the vertical position.
To produce good welds, you must maintain the
proper angle between the electrode and the base metal.
In welding upward, you should hold the electrode at 90
degrees to the vertical, as shown in figure 7-36, view A.
When weaving is necessary, oscillate the electrode, as
shown in figure 7-36, view B.
In vertical down welding, incline the outer end of
the electrode downward about 15 degrees from the
horizontal while keeping the arc pointing upward to-
ward the deposited molten metal (figure 7-36, view C).
When vertical down welding requires a weave bead, you
should oscillate the electrode, as shown in figure 7-36,
Vertical welding is used on most types of joints. The
types of joints you will most often use it on are tee joints,
lap joints, and butt joints.
When making fillet welds in either tee or lap joints
in the vertical position, hold the electrode at 90 degrees
to the plates or not more than 15 degrees off the hori-
zontal for proper molten metal control. Keep the arc
short to obtain good fusion and penetration.
TEE JOINTS. To weld tee joints in the vertical
position, start the joint at the bottom and weld upward.
