INTRODUCTION 1.1 THE BACKGROUND 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 […]

The machine is designed to serve with an output of 250A. it has two pats which are the primary and secondary parts. The primary part, through which voltage is supplied to the machine has 180 turns which is made of 2mm2 S.W.G 14 copper coil. The secondary part has 45 turns made of 4mm2 S.W.G 8 copper coil. Both turns are wound on separate limb of the laminated core. The voltage from primary turns flows to the secondary turn by induction […]
This project is titled the designing and construction of an electric A.C arc welding machine. Electric Arc Welding Machine of 220 Volts and output voltage of 32volts. A core type step-down transformer and choke are essential as the voltage or the arc is 32v. The choke is necessary to displace the phase relationship of the voltage and current so that the heat of the arc may be maintained by ensuring that zero points of current and volta […]

ABSTRACT This project is titled the designing and construction of an electric A.C arc welding machine. Electric Arc Welding Machine of 220/240 Volts and output voltage of 100volts. A core type step-down transformer and choke are essential as the voltage or the arc is usually between 50 and 100volts. The choke is necessary to displace the phase relationship of the volta […]
ABSTRACT This project is titled the designing and construction of an electric A.C arc welding machine. Electric Arc Welding Machine of 230/240 Volts and output voltage of 32volts. A core type step-down transformer and choke are essential as the voltage or the arc is 32v. The choke is necessary to displace the phase relationship of the voltage and current so that the he […]
ABSTRACT This work entitled "Design and construction of a portable plastic welding machine. The purpose of this thesis is the design and construction of portable welding machine for welding plastic, which will have the ability to be easily transferred to areas where there may be leakage or damage to plastic in order to easy, quickly and inexpensively repair the damage. The machine should be constructed in such a way that will be oper […]
