           Job Sequence

           •  Cut the plate by using hacksaw cutting as per drawing
           •  Set the sheets and tack weld in the form of a “Corner” joint on the welding in flat position
           •  Fill the crater

           •  Manipulate the torch and filler rod in the correct position with respect job
           •  Stop the weld at the left-hand edge of the joint after filling up in the crater at the end of the weld
           •  The angular distortion between the vertical and horizontal sheets of the Tee joint is automatically controlled
           •  The current set is 10 to 15 amperes
           •  At the end of the welding perform the carter filler treatment by repeating the torch switch   ON-OFF

           •  Cut the arc and hold at the finishing point unit molten metal solidifies
           •  Visual inspection: slight convexity, uniform width, uniform ripples and free from under cut at the toes of the
              weld indicate a smooth
