Use Basic Hand
Tools and
Equipment (UT)
Welders and any work related to metal works
cannot do their job without these material
and tools. These materials make work of
welder easier in building walls, structures and
walkways. Here are some SMAW materials
and tools
A. Measuring Tools
Measuring tools are
used to measure the
dimension of an
object or metal
Pull-push rule
This flexible rule when extended will
support itself, but can also be wont
to measure curved, irregular
surfaces. Steel tape rule blade is
typically ½ inch wide and 72 inches
long. The graduation is sixteenths,
except for the first 6 inches which
are graduated in thirty-seconds of
an inch
Steel tape
It is analogous to a steel
tape rule apart from its
flexible number of feet
that are marked on the
tape. The tape is 3/8-
inch-wide and available
in lengths from 25 to 100
feet.
Steel rule
This is the foremost commont tool utilized in the tool room.
It is made of tempered steel about 1/8-inch-thick and ¾ inch wide
and 6 to 12 inches long. The same style may ba obtained in length
from 1 to 48 inches.
Try square
It is an
instrument used
to measure the
square of an
object
Combination
square
It is an instrument
combined with 45°, 90°,
and a protractor
Micrometer
caliper
It is a precision
measuring instrument
used to measure
dimensions in
thousandths of an inch
Vernier caliper
It is a precision measuring instrument
used to measure the inside, outside
diameter, as well as the depth of hole
and slot
Dividers
These are used for
measuring or
setting distances,
and to layout arcs
and circle.
