Practicing Running Bed Welding
Tuesday, 11th September 2012. We had Welding Workshop in the afternoon. Our instructor, Cikgu Hj Kula demonstrated on how to weld 'running bed' on a work piece.
How to weld a 'running bed' on a work piece?
By using a welding torch, the flame produced is from two different types of gas which are acetylene gas & oxygen gas. First, you turn on and let out a little bit of the acetylene gas. Put the torch near the back of your hand to feel if there is gas coming out from the nozzle. To light the flame, use the spark gun to ignite the flame. Then, open the oxygen so that we get a neutral flame for multipurpose welding.
To weld a running bed on a workpiece, first melt the metal from the right edge of the workpiece. Since we are starting from the right, we are doing a leftward direction. As soon as the metal starts to melt, move the torch in a steady speed and towards the left. You can either use a circular motion or just weld the molten metal to the left. Make sure the width of the running bed is approximately equal all the way. Repeat the steps and practice it for three times. There would be three lines of running bed altogether.
