WELDER - CITS

Maintain the same electrode angle as in the root bead.
If the leg size is less than 10mm then deposit a third run using the same technique used for the second run.
Clean the final covering bead thoroughly.

Stop the electrode weaving for a moment at the toes of the weld to avoid undercut. Fill the crater at the end of
the bead.
Inspection of fillet weld

Inspect the fillet welds for defects, correct shape and size of fillet and equal leg length on either side of the weld.
Open corner joint on MS plate 10mm thick in flat

position (SMAW)

Objectives: At the end of this exercise you shall be able to
• set the plates to form an open corner joint at 90° with specified root gap in flat position
• tack weld the pieces as an open corner joint at both ends
• deposit root run in the corner joint with the formation of a KEYHOLE and obtain complete penetration
• deposit uniform covering layers in the corner joint using weaving of electrode and complete the weld
• inspect the welded joint for penetration, reinforcement and throat thickness.
