steel pipe column that is to be welded to a baseplate. The
symbol tells the welder that the pipe is to be beveled at
a 30-degree angle followed by a bevel groove weld all
around the joint. This is followed by a 1/2-inch fillet
weld that is also welded all around the joint. Finally,
finish the fillet weld by grinding it to a flush contour. As
the field weld symbol indicates, all welds are to be
accomplished in the field.
For additional information about welding symbols,
refer to Symbols for Welding and Nondestructive Test-
ing, ANSI/AWS A2.4-86.
Mishaps frequently occur in welding operations. In
many instances, they result in serious injury to the
welder or other personnel working in the immediate
area. In most cases, mishaps occur because of careless-
ness, lack of knowledge, and the misuse of available
equipment. Precautions that apply to specific welding
equipment are pointed out in the chapters that cover that
equipment. In this section we are particularly interested
in such topics as protective clothing, eye protection
devices, and practices applicable to the personal safety
of the operator and personnel working nearby.
Proper eye protection is of the utmost importance.
This covers the welding operator and the other person-
nel, such as helpers, chippers, or inspectors, who are in
the vicinity of the welding and cutting operations. Eye
protection is necessary because of the hazards posed by
stray flashes, reflected glare, flying sparks, and globules
of molten metal. Devices used for eye protection include
helmets and goggles.
NOTE: In addition to providing eye protection,
helmets also provide a shield against flying metal and
ultraviolet rays for the entire face and neck. Figure 3-56
shows several types of eye protection devices in com-
Flash goggles (view A) are worn under the welders
helmet and by persons working around the area where
welding operations are taking place. This spectacle type
of goggles has side shields and may have either an
adjustable or nonadjustable nose bridge.
Eyecup or cover type of goggles (view B) are for
use in fuel-gas welding or cutting operations. They are
contoured to fit the configuration of the face. These
goggles must be fitted with a shade of filter lens that is
suitable for the type of work being done.
NOTE: The eyecup or cover type of goggles are
NOT to be used as a substitute for an arc-welding
For electric arc-welding and arc-cutting operations,
a helmet having a suitable filter lens is necessary. The
helmet shown in view C has an opening, called a
