ABSTRACT
The Student Industrial Work Experience Scheme established by the Federal Government of Nigeria was aimed at
exposing students ofhigher institutions to acquire industrial skills and practical experiences in their approved courses
of study and also to prepare students for the industrial work situation which they are likely to meet after graduation.
This technical report is based on my Six months of Industrial Training at Alcon Nigeria Limited Fabrication Yard,
Port Harcourt River State. This report highlights how fabrication yard is set up and managed. It consists of how
necessary designs are carried out especially with the Plasma CNC to suit the requirement of project being carried out
in different project sites. This report also consists of danger and hazards associated with the Plasma CNC. It states
also some challenges faced and solutions.Also important to point out is how the Mechanical Department is set up in
Alcon Nigeria Limited Woji Fabrication Yard, Port Harcourt, Nigeria. I have learnt a lot from Alcon Nigeria Limited
in just this my few months of internship. So much that I might not be able to mention all in this report but the
outstanding ones of course will be pointed out with an extent of clarity.

CHAPTER ONE
1.0 ABOUT THE INDUSTRIAL TRAINING FUND (I.T.F)
In October 1971, the Federal Government established the Industrial Training Fund
(I.T.F). In its policy statement No.1 oublished in 1973, a clause was inserted dealing with
the issue of practical skills among the locally trained professionals in the tertiary
institutions especially the Universities of Technology, Monotechnics, Polytechnics,
Colleges of Education and Technical Colleges. Section 15 of the policy statement states
clearly that “Great emphasis will be placed on assisting certain products of the post-
secondary school system to adapt or orientate easily to their possible post-graduation job
environment”, subsequently leading to the launch of a scheme known as Student’s
Industrial Work Experience Scheme (SIWES).
1.1 ABOUT SIWES
The SIWES was launched in 1973 by the Industrial Training Fund (I.T.F) as a
programme designed to impart the undergraduate of the nation’s tertiary institution
studying various professional courses with the practical methods of performing
professional functions to real life situations on site, in the office or even in the factory
and how they apply themselves mentally, intellectually and physically in relation to what
they have been taught in the classrooms theoretically. It works with the following
professional bodies to function effectively across tertiary institutions nationwide. These
are: the Nigeria University Commission (N.U.C), National Board for Technical
Education (N.B.T.E), and the National Commission for Colleges of Education
(N.C.C.E). Thus, equipping the students with the necessary skills and technical

9. 2
knowledge to make them highly competitive and professional individuals in the Larbour
Market.
1.2 SCOPE
The scheme as conducted by the Industrial Training Fund (I.T.F), through their
representative liaison units and offices situated within the various institutions and in major
cities or towns in Nigeria with the necessary Industrial rudiments needed to corroborate,
praticakize and then actualize the required technical knowledge. The Industrial Training
experience not only put them in real life situation but also exposes their practical
knowledge of the course of study, consequently perfecting this knowledge thereby
producing very competent and versatile professionals.
1.3 AIMS AND OBJECTIVES OF SIWES
Main aims and objectives of SIWES are as follows:
1. To provide students with industrial skills and needed experience while the course of study;
2. To create conditions and circumstances, which can be as close as possible to the actual
workflow;
3. To prepare specialists who will be ready for any working situations immediately after
graduation;
4. To teach students the techniques and methods of working with facilities and equipment that may
not be available within the walls of an educational institution;
5. To give students the ability to try and apply the given knowledge.

10. 3
The objectives of SIWES programme are all about strengthening future employees. Such program
is successful attempt to help students to understand the underlying principles of their future work.
After passing the programs, the student can concentrate on the really necessary factors of his or
her work.

2.3 THE MECHANICAL DEPARTMENT
The Mechanical Department in ALCON NIG LTD is a place where operations such as
fitting, welding, machining, and other mechanical operations are being carried out. Simple
mechanical components and complex mechanical components are being produced in this
department, with the aid of available machines.
2.4 MACHINES IN MECHANICAL DEPARTMENT AND THEIR USES
PLASMA CNC CUTTER
A Plasma CNC cutting torch is a commonly used tool for cutting metals for a wide variety of
purposes.
LATHE MACHINE
A lathe machine is a machine tool which is used to remove metals from a work piece to give a
desired shape and size.
BENDING MACHINE
A bending machine is used to bend materials, especially sheet metals to a required angle.
IMET CENTRALIZED CUTTING MACHINE
This machine act like an automated saw blade. It's used for cutting metals like pipes, rods, etc
THREADING MACHINE
This machine is used to produced threads on a cylinder or cone.

22. 15
DRILLING MACHINE
A drilling machine, also called a drill press, is used to cut holes into or through metal, wood, or
other materials.
HYDRAULIC PRESS
A hydraulic press is used for almost all industrial purposes. But basically it is used for transforming
metallic objects into sheets of metal.
MAGNETIC DRILLING MACHINE
A portable magnetic drilling machine is used on steel or other magnetic materials. It gives an
accuracy of 0.01 mm to 0.05mm in steel or other magnetic material.
ANGLE GRINDING MACHINE
Angle grinders may be used for removing excess material from a piece. There are many different
kinds of discs that are used for various materials and tasks, such as cut-off discs (diamond blade),
abrasive grinding discs, grinding stones, sanding discs, wire brush wheels and polishing pads.
INTERNAL GRINDING MACHINE
This machine is used basically to remove excesses in the holes of a plate. It is also used for
polishing some surfaces that might seem difficult to archive with the angle grinder.

23. 16
2.5 PLASMA CUTTING
Plasma cutting is a process that cuts through electrically conductive materials by means of an
accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless
steel, aluminum, brass and copper, although other conductive metals may be cut as well. Plasma
cutting is often used in fabrication shops, automotive repair and restoration, industrial
construction, and salvage and scrapping operations.
2.5.1 CNC CUTTING METHODS
The Plasma Cutter in ALCON Nigeria Limited has a CNC Table. Some plasma cutter
manufacturers build CNC cutting tables, and some have the cutter built into the table. CNC tables
allow a computer to control the torch head producing clean sharp cuts. Modern CNC plasma
equipment (just like the one used ALCON NIG LTD) is capable of multi-axis cutting of thick
material, allowing opportunities for complex welding seams that are not possible otherwise. For
A CNCPLASMA CUTTING GANTRY

24. 17
thinner material, plasma cutting is being progressively replaced by laser cutting, due mainly to the
laser cutter's superior hole-cutting abilities.
A specialized use of CNC Plasma Cutters has been in ALCON NIG LTD. Software processes
information on ductwork and creates flat patterns to be cut on the cutting table by the plasma torch.
CNC Plasma Cutters are also used in ALCON NIG LTD to create decorative metalwork. For
instance, commercial and residential signage, wall art, address signs, and outdoor garden art.
2.6 MAJOR PARTS OF THE PLASMA CNC MACHINE
The Major Parts of the plasma CNC are as follows:
1. Plasma Gantry
2. Gas console Machine
3. Fume extracting Machine
4. CNC Machine
Other minor parts of the plasma CNC are as follows :

26. 19
2.7 OPERATION OF THE PLASMA CNC
Plasma cutters work by sending an electric arc through a gas that is passing through a constricted
opening. The gas can be shop air, nitrogen, argon, oxygen. etc. This elevates the temperature of
the gas to the point that it enters a 4th state of matter. We all are familiar with the first three: i.e.,
solid, liquid, and gas. Scientists call this additional state plasma. As the metal being cut is part of
the circuit, the electrical conductivity of the plasma causes the arc to transfer to the work.
The restricted opening (nozzle) the gas passes through causes it to squeeze by at a high speed, like
air passing through a venture in a carburetor. This high speed gas cuts through the molten metal.
The gas is also directed around the perimeter of the cutting area to shield the cut.
In many of today's better plasma cutters, a pilot arc between the electrode and nozzle is used to
ionize the gas and initially generate the plasma prior to the arc transfer.
Other methods that have been used are touching the torch tip to the work to create a spark, and the
use of a high-frequency starting circuit (like a spark plug). Neither of these latter two methods is
compatible with CNC (automated) cutting.
While these parts are all referred to as consumables, it is the electrode and nozzle that wear and
require periodic replacement.
CNC (computer numerically controlled) plasma cutters fully automate the shape production
process. Early CNC machines used a tape with small holes punched through to provide
instructions to a primitive (by today's standards) computer.
The CNC unit in ALCON Nig Ltd uses an expensive limited production computers made
specifically for running burning machines. This provides a good cut quality and production speed.

27. 20
In CNC cutting, you arrange your shapes on the computer screen and cut them automatically,
without having to touch the material. CNC software lets you program pauses for piercing, scale up
or down in seconds, set acceleration and deceleration at corners, and other functions not possible
with electric eye units.
2.8 HAZARD INVOLVED IN PLASMA CUTTING
Some hazards involved in the Plasma cutting operation, are as follows.
1. Fire Hazards
The plasma cutting arc blows out hot metal and sparks, especially during the initial piercing of the
metal. It also heats the work piece and cutting torch, all of which can cause fire and burns. To
protect my eyes while plasma is cutting, I was taught to wear approved safety glasses with side
shield. For increased protection, I was also encouraged to use a face shield or helmet in conjunction
with safety glasses.
To protect my body from flying sparks and hot metal, I always wear dry, undamaged, flame-
resistant clothing and gloves.
The intensely hot and powerful plasma arc can quickly cut though gloves and skin. To prevent
injury, I do not grip material near the cutting path.
Since heat and sparks can ignite flammable materials, I move all flammables at least 35 ft. away
from the cutting area or protect them with flame-proof covers. I Take extra care to close off

28. 21
small cracks and openings in partitions, as sparks can easily pass through them. Never cut on
closed or pressurized containers, such as tanks or drums
2. Well Grounded
Plasma arc cutting torches are typically designed with safety interlock systems that turn off the
machine if operators loosen the shield cup or if the tip touches the electrode inside the nozzle.
However, plasma arc cutting requires higher voltages than welding to start and maintain the arc -
typically 110 to 400 VDC - and touching live electrical parts can cause fatal shocks or severe
burns. Poor connections and bare spots on cables increase the possibility of electrical shock. I was
taught how to inspect these items daily and replace, not repair, any worn cables or broken
connections.
Because water conducts electricity very well, I avoid wet working conditions (even body
perspiration can lower the body's resistance to electrical shock). I insulate myself from work and
ground by standing on a dry rubber mat or dry plywood sheet big enough to cover the full area of
your contact with the work or ground. Be cautious, as both rubber and wood can ignite..
3. Dim the Lights
Arc rays produce intense visible and invisible (ultraviolet and infrared) light rays that can burn
eyes and skin. Proper clothing protects your skin, but myeyes need the additional protection
provided by a face shield or safety glasses outfitted with the correct lens shade.
4. Clear the Air
Cutting any metal produces fumes and gases, and breathing them can create health hazards. I was
taught to keep my head out of the fumes and do not breathe them.

29. 22
When cutting coated metals - such as galvanized steel, lead- or cadmium-plated steel - remove the
coating from the cutting area if possible. These coatings, and any metal containing these elements,
can give off toxic fumes when cut with a plasma arc. When cutting coated metals, ventilate the
cutting area and I use an exhaust hood or suction system - positioned at the arc - to keep the
breathing zone safe and clear of fumes. If necessary, wear an air-supplied respirator.
5. Gas Systems
Plasma arc cutting systems use shop air and sometimes compressed gases, typically nitrogen.
When using cylinders, I securely chain them to a stationary, upright support or cart at all times.
When moving or storing a cylinder, fasten the threaded protector cap to the top of the cylinder.
This shields the valve system from impact damage.

30. 23
2.9 SAFETY WHEN USING THE PLASMA CNC
Proper eye protection and face shields are needed to prevent eye damage called arc eye as well as
damage from debris. It is recommended to use green lens shade.
Leather gloves, an apron and a jacket are also recommended to prevent burns from sparks and hot
metal.
Working in a clean area free of flammable liquids, materials and gases is very important. Sparks
and hot metal from a plasma cutter can quickly cause fires if they are not isolated from flammable
objects. Plasma cutters can send hot sparks flying up to 5 feet away in certain situations. The
operator of the machine is typically blind to any fire that has started because they are behind their
face shield. Take safety precautions to make sure your work area is free of fire hazards.

CHAPTER FOUR
4.0 CONCLUSION AND RECOMMENDATION
4.1 Conclusion:
My Six Months Internship at ALCON Nigeria Limited has given me a huge advantage by helping
me appreciate practical in engineering and also helping me see how a firm operates by exposing
me to the Fabrication Yard, its facilities, and how machines (especially the Plasma CNC) operates.
4.2 Recommendation:
As an experienced Mechanical Engineering Student, I saw some limitations in my company and
in Nigeria based companies as a whole. I will fully admit that there are problems in our everyday
life, which spans from the academic level, into the industries. I will therefore recommend that
more research and learning should be encouraged in Nigeria this will help advance the level of
intelligence the Nigeria based companies will exhibit, and also help the upcoming generation to
grow thereby.
