           Fillet ‘T’ joint in flat position (1F)

           Objectives: At the end of this exercise, you shall be able to

           •   prepare and make ‘T’ joint in flat position.


           Set the pieces in alignment forming 92° between the plates Fig 1.
           This presetting to 92° is done to compensate the effect of shrinkage forces when weld deposit cools down.
           Tack-weld the pieces at both ends of the Tee joint by using a 3.15mm dia. medium coated M.S. electrode and
           110/120 amps welding current.
           Ensure the tacks are well fused at the root.
           Check the alignment of the Tee joint after tacking.
