Abstract Welding is a way of heating pieces of metal using electricity or a flame so that they melt and stick together. It can simply be defined as the process of joining two or more pieces of metal to make the act as a single piece. This is often done by melting the work pieces and adding a filler material to form a pool of molten material that cools to become a strong joint. Because of its strength, welding is used to join beams when constructing buildings, bridges and other structures. Welding can also be used to join pipes in pipelines, power plants at the construction sites and in home appliance. Furthermore, welding is used in shipbuilding, automobile manufacturing and repair, aerospace applications. There are many kinds of welding which include arc welding, resistance welding, gas welding among others. Emphasis will be laid on arc welding because it is the most common type of welding as well as the main aim of this project.
DESIGN AND CONSTRUCTION OF AN INVERTER TYPE ARC WELDING MACHINE
ABSTRACT An inverter is an electronic device that converts direct current (DC) to alternating current (AC) the converted Ac can be at any required voltage and frequency with the use of appropriate transformers, switching and control circuit. It’s simple put, is an electronic box that makes household electricity for everyday items. It... Continue Reading

ABSTRACT A 1.25KVA (2000W) inverter generator was designed, constructed and certified Ok. In this project, the design of the inverter generator is aimed at satisfying the need of converting, a D.C source of supply (12v battery) to an A.C voltage of 220v. The inverter range of output is between 200-220v. Since the inverter was designed to step-up... Continue Reading
ABSTRACT This project review the conformability of uninterrupted power supply through the use of inverter. An inverter is a system that converts a direct current to an alternating current. However, inverter is of different categories base on power rating such as 1KVA, 1.5KVA,2KVA, 5KVA etc. Moreover, since the invention of inverter, some... Continue Reading
ABSTRACT This project is titled the design and construction of a DC to AC inverter system. It is designed to meet up with the power demand in the offices and in homes in the absence of power supply from the national supply authority, NEPA. In order words the device / item serves as a substitute for NEPA which almost monopolises the power supply to... Continue Reading
ABSTRACT Power inverter is an electrical appliance that can be used with DC battery as an alternativesource of energy supply in the event of power failures and energy crisis. It is cheap, clean,very conducive and silent when in operation and a very reliable source of power supply as togenerator. Modern research and technologies have shown that... Continue Reading
ABSTRACT This inverter is designed to convert ac power from higher capacity dc batteries to A.C voltage (power) for systems that use ac only. It uses 24v battery D.C times 2, which is converted by the MOSFET to A.C. it is used I.C. with the model number SG3525 where the four MOSFET is connected to it. It consists winding which enable to determine... Continue Reading
