DESIGN AND CONSTRUCTION OF AN INVERTER TYPE ARC WELDING MACHINE

 

CHAPTER ONE

INTRODUCTION

 1.1 BACKGROUND OF THE STUDY

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.

Arc welding is the process of welding that utilizes an electrical discharge (arc) to join similar materials together. Equipment that performs the welding operation under the observation and control of a welding operator is known as welding machine. To solve the problem of weight and size of conventional arc welding machine, it is necessary to design an inverter. The inverter provides much higher frequency than 50Hz or 60Hz supply for transformer used in welding. So transformer of much smaller mass is used to permit the handling of much greater output power. The welding noise produce by conventional arc welding machine is reduced by selecting the operating frequency over the hearing of human ability. The choice of 20Khz for the inverter type arc welding machine was determined to meet the above expectation. The output welding current is controlled by controlling the power supply for transformer at high frequency. This power supply is provided by a frequency inverter. Power switch IGBTs (Insulated Gate Bipolar Transistor) or MOSFETs is used for the inverter design due to its high switching. The control circuit use to control the output welding current is design to drive the power switch at high frequency. Insulated Gate Bipolar Transistor power switch is more efficient and less prone to failure than MOSFETs power switch.

1.2  AIMS AND OBJECTIVES OF THE PROJECT

The main aim and objective of this project is to design and build and arc  welding machine that operates on 36vdc at variable frequency which of benefit to urban area. This reduces the weight and size of the transformer use for welding. To have an arc welding machine that is more efficient which produce neat welding. 

1.3  SIGNIFICANT OF THE STUDY

The significant of this project is that it seeks to develop an arc welding machine that is cost effective, strong and portable. Not only that the arc welding machine is strong and portable, it is also mobile.

1.4 LIMITATION OF THE PROJECT

The project has certain limitations which are mentioned below.

Ø  This project cannot weld bigger gauge of metals.

Ø  The welding time and power depends on the battery input power.

Ø  You are to have bands of battery for reliability when using battery.

Ø  The machine must be used by a qualified welder. Welding can endanger the operator or people near the working area. Therefore, the performance of welding and cutting must only be done under the comprehensive observation of all relevant safety regulation.

Ø  Switch function modes during welding could potentially damage the equipment. A safety switch is necessary to prevent the equipment from electric leakage. Use only high quality welding tools and equipment with this inverter type arc welding machine.

1.5    PROJECT REPORT ORGANIZATION

The organization of the project report is well detailed and vast in its coverage. It covers all the activities encountered during the research work. The first chapter is the introductory chapter which covers the background, project objectives, project justification, and scope of the project. Chapter two presents the literature reviews. Chapter three covers the system analysis and design methodology in details. Chapter four presents the system implementation which entails the circuits diagram of different stages and also the complete schematic diagram with necessary calculation involve in the design. Chapter five is emphasis on conclusion, problem encountered during project design, recommendations and suggestion for further improvement. Fig1.1 depicts an overview of project report organization.

I actually googled and saw about iproject master, copied the number and contacted them through WhatsApp to ask for the availability of the material and to my luck they have it. So there was a delay with the project due to the covid19 pandemic. I was really scared before making the payment cause I’ve been scammed twice, they attended so well to me and that made me trust the process and made the payment and provided them with proof, I got my material in less than 10minutes

I did not see my project topic on your website so I decided to call your customer care number, the attention I got was epic! I got help from the beginning to the end of my project in just 3 days, they even taught me how to defend my project and I got a 'B' at the end. Thank you so much iprojectmaster, infact, I owe my graduating well today to you guys...
