In a certain job, a specific tool is recommended to used in a specific task or job.
This lesson will give the emphasize on how to used tools and equipment .

What’s In

Can you give some tools and do you at home?

Can you identify the kinds and functions each tools and equipment?
What’s New

Today, it is a healthy competition to everyone with respects to their skills. One of the
secrets to earn skills is constant correct practice and attitude towards work plus the
tools and equipment used in a task or job. Types of tools and equipment is one of the
keys for success in the field of welding.

What Is It
BASIC TOOLS AND EQUIPMENT IN WELDING

 MEASURING TOOLS
 CUTTING TOOLS
 DRIVING TOOLS
 HOLDING TOOLS
 POWER TOOLS
 WELDING MACHINE

Measuring Tools

Pull-push rule. This flexible rule when extended will support itself, but may
also be used to measure curved, irregular surfaces. Steel tape rule blade is usually
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 is similar to a steel tape rule except for 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 most
common tool used in tool room. It is made of tampered steel about 1/8-inch-thick
and ¾ inch wide and 6 to 12 inches long. The same style maybe obtained in length
from 1 to 48 inches.

Try square is an instrument used to measure the squareness of an object.

Combination square. It is an instrument combined with 45°, 90° and a


protractor.

Micrometer caliper. Is a precision measuring instrument used to measure


dimensions in thousandths of an inch.
Vernier caliper is a precision measuring instrument used to measure the
inside, outside diameter, as well as depth of hole and slot.

Dividers. These are used for measuring or setting of distances, and to lay
out arcs and circles.

CUTTING TOOLS

Hacksaw is a tooth cutting tool usually with a solid and adjustable frame.
The main parts are handles, blade, tightening screw and nuts. The tool is mainly
used in cutting metals like plates, pipes, rods, bars, angular, etc. but of minimal
thickness, width and length. Sometimes this tool is used for cutting plastic pipes and
other materials that suit to its purpose.
Frame. It is the main body of the hacksaw which holds the blade. The different
types of frames are the following:

a) Fixed or solid frames are intended to hold only one size of blade at about 10
inches long.

b) Adjustable
frame is frame that
can be adjusted to hold blades of different sizes such as 10, 12 and 14 inches in
length.

Blade. It is made of thin, high grade steel usually 1.27 mm thick and 30.48cm
long with an inclined row of teeth serving as cutter.

The two types of blades are:


a) All hard In this type, the entire blade is hardened and tempered, making it
very brittle. Use this type in cutting steel and cast iron.

b) Flexible back. In this type, only the teeth portion is hardened and
tempered, making the blade springy and less likely to break.

The following are the recommended teeth-per-inch of blades for different kinds of
stocks to be cut:
a) 14 teeth-per-inch. It is used for brass, aluminum, cast iron and soft iron.
b) 18 teeth-per-inch. It is used for drill rod, mild steel, tool steel and general work

c) 24 teeth-per-inch. It is recommended for thin tubing and pipe.

Files are made of high-grade steel


which are hardened and tempered. Each file has rows of teeth that form, shape and
finish metal by removing small chips and smoothing rough edges of the metal
surface. They differ in length, shape, cut and coarseness.
Kinds of files:

1. Mill file a single-cut file used for filing and finishing brass and bronze.

2. Flat file is usually rectangular in shape and tapered slightly in width and
thickness. It is one of the most commonly used files for general work.

3. Square file is intended for filing square or rectangular holes.

4. Round file is used primarily for enlarging holes.


5. Half-round file is used for filing curved or concave surfaces.

6. A triangular file is used for filing surfaces that meet at least 90º. It is
exclusively used for sharpening wood saws and for smoothening rectangular
opening. It is also known as three-square file.

Cold chisel. A wedge-shaped tool used to shear, cut, and chip metal.

Types of cold chisel and their particular functions:


1. Flat chisel is used for chipping flat surfaces; cutting off rivets or metal
fasteners, thin sheets, and small bars; and for general purposes. Its
cutting-edge ranges from 13 to 25mm.

2. Cape chisel has a narrow edge suited for cutting narrow grooves or slots.

3. Diamond-point chisel has a diamond-shaped cutting edge intended to cut V


- grooves.
4. Round-nose chisel has a round nose cutting edge for cutting round and
semi-circular grooves.

Scraper is used in removing points, burrs and sharp edges from metal surface
and similar parts. This tool is made of hardened steel of various shapes that fit
according to each purpose. There are bearing scrapes, flat, sharper, three-connected
scraper. Below are types of scrapers and their uses:

1. For the removal of the high spots on metal surface.

2. For scraping the surface of cylindrical bearing when fitting shafts into
place.

3. For the removal of burrs and sharp internal edges from soft brushing and
similar parts.

Punches are used for permanent marking on the surface of metal.


Kinds and uses of punches
 Prick punch a small center punch which is also known as a layout
puncher. Its point is placed an angle of 30 degrees.

 Center punch has one end guard to a 90 degrees conical point.

DRIVING TOOLS

Hammers

Ball peen hammer is used for straightening bending and deforming metals. It
has two faces. One is flat in striking cold chisels and punches. The other side the
“peen” is rounded for bending and shaping metals. Ball peen hammer generally has
a wood or fiberglass handle measuring 10-16 inches long. Head weight ranges from
2-48 oz. A 20oz hammer is good for general purpose.

Chipping hammer is used for removing slag on weld and with two faces, the
tapered from one side and round pointed on the other side.

Wrench is used for loosening and tightening light and heavy nuts and bolts.
There are different kinds and sizes of wrenches designed according to uses and
functions:

1. An adjustable wrench has a movable jaw which makes it adjustable to


various sizes of nuts. A heavy type of adjustable wrench is the monkey/pipe wrench.
2. Oxy acetylene wrench - A type of wrench used for tightening hose and fitting
connection on oxy-acetylene unit.

3. An open-ended wrench is one that is made to fit one size of nut or bolt. This
is the most inexpensive type of wrench that is quite efficient in ordinary situations.
Single – ended

Double – ended

4. A closed-end wrench is similar to a single ended wrench, but as it entirely


encloses a nut, there is a little danger of the wrench slipping off the nut or the jaws
spreading apart.
Single – ended

Double – ended

5. Socket wrench is a tool with a usually interchangeable socket to fit over a


nut or bolt.

6. Screwdriver is hand tool that is designed to turn screws. The blade is


made of steel, attached to one end of a wooden or plastic handle. The other kinds of
screw drivers are called a Phillips screw driver, standard/flat screw driver, allen
screw driver/wrench and helical-ratchet screw driver.

Allen screw driver/wrench

Helical-ratchet screw driver

HOLDING TOOLS

Clamps are made of different sizes and appearance that are fitted to its
purpose. These devices have been designed to hold work securely when performing
skills through grinding, bending, fitting and cutting of metals. Some types of clamps
and metal vises are:

1) Tool maker clamp is used for holding small parts both at the bench and at
the machine. This tool is also known as a parallel clamp.

2) C-Clamp is an all-purpose clamp that is generally used for all kinds of


work.

3) Drill vise is a sturdy steel vise with movable jaw that easily goes back or
forth by raising the handle.
4) Machinist vise is a work holding tool for machining activity.

5) Hand vise V block with clamp is used to hold metal stocks for small
machining operation.

6) Vise Grip is a tool used to grip the stock tight enough to hold the object.

7) Tong is used to hold the metal to be forged and must be held securely
while working.
8) Pliers are used for holding, cutting and twisting wires.
