CHAPTER ONE - [ Total Page(s): 2 ]CHAPTER ONE1.0 INTRODUCTIONIn the past with the necessary of metals it always seems impossible to join two metals together with grooving riveting, this idea leads to alternative of finding a lasting solution to the problem. This brought about the idea of a welding machine with a well laminated core and coil wound together to form a high rated transformer which is immersed in a can of oil.Welding is the most economical and efficient way to join metals permanently. It is the only way of joining two or more pieces of metal permanently to make a single piece. Welding is vital to our economy. ... Continue Reading
CHAPTER TWO - [ Total Page(s): 3 ]ii. OXIDIZING FLAMEOxidizing welding flame are produced hen slightly more than one volume of oxygen is mixed with one volume of acetylene. To obtained this type of flame, the flow of oxygen is then increased until the inner cone is shortened to about one tenth of it original length when the flame is properly adjusted, the inner cone is pointed and slightly purple. An oxidizing flame can also be recognized by it distinct hissing sound. The temperature of this flame is approximately 6300oF (3482oC) at the inner cone tip. The flame is hotter than the neutral carburizing flame.Metals can be ... Continue Reading
CHAPTER THREE - [ Total Page(s): 4 ]CHAPTER THREE3.0 GENERAL DESCRIPTION AND ITS WORKING PRINCIPLERegarding the design and fabrication of this project several information were gathered through consultation of previous journals text books and internet.Definition: “welding is the process of joining together two pieces of metal so that bonding take place at their original boundary surface s. when two parts to be joined are melted together, heat or pressure or both is applied and with or without added metal for formation of metallic bond. Welding is a major technology in present day industry and has important effect and ... Continue Reading

Winding design in transformer construction must be done perfectly and accurately. Since winding the stacked lamination there are limited space in which the winding can occu ... Continue Reading
CHAPTER FIVE - [ Total Page(s): 10 ]Now let assume a load having a power factor such that the secondary current is in phase with E2 the primary current must now have two component.1. I1 to maintain the useful flux2. I2 to neutralize the demagnetizing effect of the secondary current.Since the flux of each limb is link only with the winding by which it is produced, it is referred to as leakage flux and its responsible for reducing an e.m.f. of self inductance in the winding with which it is linked. The reluctance of the part of the leakage flux x OL is almost entirely due to the long air part and is therefore pra ... Continue Reading
CHAPTER SIX - [ Total Page(s): 1 ]CHAPTER SIX6.0. CONCLUSION AND RECOMMENDATION6.1 CONCLUSION The project is a form of providing student with appreciable skills p4actically designed to expose or equip them with real working operation of machine and how they are being constructed and a better understanding of one’s own career goals and for the progress of the nation.The project seemed easy and simple but later on turn to be useful and interesting project for Engineering students. With all the problems faced and solved in this project has improved my skill and experience in any of such project. I ... Continue Reading
