    • RIGHT WARD WELDING
          The welding torch is held with the right hand and the filler rod in the left. Welding begins at the left hand side of the joint and proceed towards the right, hence the name right ward technique.  The direction of welding is opposite to that when employing the left ward technique.  Also, in the right ward technique the torch flame is directed towards the completed weld and filler rod remains between the flame and completed weld section.  The right ward techniques of welding are used on heavier or thicker (above 5mm) base metal, weld with penetration or approximately 12mm can be achieved in a single poss. The welding electrode and blow pipe is made to heat, and the appropriate angle usually at 40o – 50o along the joint and with the work respectable for uniform welding and are kept move in a straight line.

      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 join ... 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 ( ... Continue reading---
