              Ensure the tacks are well fused having a 15 mm length
           Check the alignment after tacking.

           Welding a fillet joint
           Place the joint for flat position welding. (Fig 3)

              Fig 3













           Hold the electrode, pointing at the corner of the joint at an angle of 45° to the plate surface. (Fig 4)


              Fig 4












           Incline the electrode 10°- 20° in the direction of travel. (Fig 5)
           Proceed to weld along the joint with a uniform travel speed.  (Fig 5)
              Watch the molten pool and freezed bead carefully for excessive build up or undercut (faults).
              Increase the speed or change the angle of the electrode to correct the above faults, if they appear.
