1.0           INTRODUCTION

In 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.

It is even said that over (50%) of the gross nation product of the industries is related to welding in one way or the other. Welding ranks high economy industrial process and involve more science and variable than those involved in any other industrial process.

The electrode is either a rod that simply carried current between the tip of the tong and the work, or a rod or wire that melts and supplies, fill metal to the joint.

The basic arc welding circuit is an alternating current (A.C) or direct current (D.C) power source connected by a “hot” cable to an electrode, when the electrode is positioned close to the work piece, an arc is created across the gap between the metal and the hot cable electrode. An ionized column of gas developed to complete the circuit.
