           Objectives: At the end of this exercise you shall be able to
           •   set and tack plate pieces in alignment as tee joint and by keeping distortion allowance
           •   set the ‘T’ joint in flat position for welding
           •   deposit root run in ‘T’ joint of proper size and penetration
           •   deposit final covering run in the ‘T’ joint of proper leg size
           •   clean the weldment and inspect surface defects on the fillet weld.
