CHAPTER ONE
1.1 INTRODUCTION
Crime is any act of omission or commission of offence that violates a written code of conduct of the land or any geographical location therefore burglar is a crime that is defined by the law of Nigeria.
Burglar proof is an engineering design to control and prevent burglars from having a direct attach or entrance into our places of having
Construction of burglar proof base on the material used such as iron (mild steel) the discovery of iron makes a turning in mains creative innovation to improve his environment conditions as it makes a basic foundation for technological feet in the field of communication production and transportation. To declare iron and steel as the voice of technology is to sat the least about its benefits taking into consideration their uses and principal properties such ass, atomic weigh 55647, atomic number 26, melting point 15400c, boiling point 30000c oxidation number 2.3 density of 7.85/m3.
The basis of all physical object made of iron depends on the knowledge of history of iron ores wining of the ores, processing of the ore into pig iron and refining of the iron are into steel of various qualities and grades. Man exploits the extensive use of iron as science and technology advances, which brought about the discovery of many uses among which is for making burglar proof.
This iron revolution gave bright hope to main concerning security, in fact it’s advantages over wood which was in use in early years ago has really given satisfaction to man iron burglar proof is termites attach free as a result of its possession of high resistance and high degree of stain this making it highly suitable and durable for security purposes and it has water resistance when coated with anti must or corrosion compare to wood.
As a result of these merits man has substituted the use of wood with metal in burglar proof making metal burglary proof could be of various designs it could be made of mud steel or iron rods throughout and many other shapes for beautification.
This will make it light in weight and more attractive

- It Aimed So much of enlightening student especially those in engineering field such as civil and mechanical engineering in area of construction as regards to their profession.
- It provides a workshop model of a true metal protector and economics of material, labour and procedures.
- It also help the student to be salt reliance hide pendent as well as even when they are out of school.
1.3 OBJECTIVES OF THE PROJECT
Some of main objectives of the project are listed below
(i) To let the student realize that they can bring a new idea to the engineering construction as this is the first attempt of constructing burglar proof with mild steel as a project
(ii) To reduce the risk of danger to human life and properties caused by wooden burglar proof
(iii) To produce decent and stronger type burglar proof
(iv) Topraticalize the theorical work done in the lecture room
(v) To make the student more exposed to the use of some complex machines in the workshop
1.4 THE IMPORTANCE FOR BURGLAR PROOF
- It encourages the students to be able to put into practice or practical aspect, the theoretical aspect of the work taught in lecture room.
- It makes the student to produce a stronger and decent types of burglar proof.
- It serves as a security for human life and his/her properties against
- It enables engineering student to think on how to protect him an life in their societies
1.5 LITERATURE REVIEW
In the past, woods were being used for burglar proof as a means of securing our residence windows but it did not give a maximum security for life and also it does not meet the wants of the people.
As time went on, technology came into existence and they take burglar proof into consideration and decided to find an alternative way, which give birth to metal burglar proof of different steel.
This burglar proof has been done in many ways with different designs irrespective taste of the prospective buyers.
But the selected design was as a result of technology improvement that is from a plate bar to mild steel so as to improve the rigidity of the burglar proof and have the ability to withstand any external forces acting on it.
1.6 WELDING PROCESS
The term welding is used to cover a wide range of bonding techniques. Welding is a manufacturing process used to join sculptural materials, usually metals or thermoplastics, by coalescence. This is often done by fusing the work pieces and adding a filler material to form a pool of molten material (the solder bath) that cools to become a strong, with pressure sometimes used in conjunction with heat, or by itself, to produce the weld. The term weldability has been defined as the capacity of metal to be welded under the fabrication conditions imposed into a specific, suitably designed structure and to perform satisfactorily in the intended service [1]. There are different types of welding process in the welding history. Few of which are listed below: Gas welding, arc welding, resistance welding,, solid state welding etc. To prevent injury and arc eyes a welder must wear personal safety equipment such as welding google, leather glove, overall, welding helmet etc.
- Gas Welding
Gas welding is a welding process that uses fuel gases and oxygen during welding operation. Gas welding is one of the oldest welding processes. Still used in industry, in recent decades it has been less widely utilized in industrial applications as other specifically devised technologies have been adopted. It is still widely used for welding pipes and tubes, as well as repair work. It is also frequently well-suited, and favored, for fabricating some types of metal-based artwork. As well, gas welding has an advantage over electric welding and cutting processes in situations where accessing electricity (e.g., via an extension cord or portable generator) would present difficulties; it is more self-contained, in this sense — hence “more portable”.
- Arc Welding
Arc welding is a method of welding that uses a welding power supply to create an electric arc between an electrode and the base material to melt the metals at the welding point. It involves the use of either direct (DC) or alternating (AC) current, and consumable or non-consumable electrodes. The welding region is usually protected by some type of shielding gas, vapour, or slag. Arc welding processes may be manual, semi-automatic, or fully automated [2], [3]. Today it remains an important process for the fabrication of steel structures and vehicles. For the purpose of work, shielded metal arc welding is used. The shielded metal arc welding is one of the most common types of arc welding [4], highly versatile and can be performed with relatively inexpensive equipment [5]. Pipeline and structural welders use this method the most because of its deep ‘penetration’ (how much it digs into the base metal), and pressure handling capabilities [6].
- Resistance Welding
Resistance welding is a welding technique in which the parts to be joined are held together under pressure and heat is produced by passing a current through the contact resistance formed between the two surfaces.
- Solid State Welding
This a process of joining two metals together by vibrating them at high frequency and under high pressure. The equipment and methods involved are similar to that of resistance welding, but instead of electric current, vibration is used to provide energy input. Welding metals with this process does not involve melting the materials; instead, the weld is formed by introducing mechanical vibrations horizontally under pressure. Broadly, welding process could be classified as plastic, fusion welding and solid- phase welding [7].
CHAPTER SEVEN
7.0 CONCLUSION
This project hasbrought-out an independent creative thinking and brainstorming with colleagues. It also prepares the student for the challenges technological practice ahead and how to cope with colleagues in teamwork.
Team work experience was acquired in the process of metal cutting and welding operation.
If certain things were considered, the project would have succeeded in producing better engineers for future challenges of our nation.
Among is the consideration of machines and tools available, which could not go round and hence much of the time wasted in the processing for waiting for others, which is precisely duration of the project.
7.1 RECOMMENDATIONS
This window burglar proof can be modified and improved upon, this can be done by using bestmaterial suitable and that can withstand and resist the factors that will affect it, such as corrosion, heat and bending.
The wealth of any society is determined by the variety and quality of the article it posses for its use and consumption. All the material things we posses are marble from the earth or from native mean white our prosperity depends upon on our ability to convert these raw materials into useful articles of consumptions prior to this will want to recommend that serious attention should be given to engineering. This will go way in adding value to the wealth of our society.
