Skill Sequence

Progression Lap, Tee and joints on M.S. plate (10 mm. thick plate)

in Overhead position by GMAW
Objectives: At the end of this exercise you shall be able to
• progression lap, tee and joints on m.S. Plate (10 mm.thick plate) in overhead position by GMAW.

It is important to ensure that the Tee and lap joint is held in the weld positioner firmly
The line of weld of the joint should be parallel to the ground and is in such as a height from the ground that it is
easily accessible to the welder depending on the height of the welder.
Ensure that the torch assembly hose, containing the spiral, filler wire, gas hose etc is long enough so that it can
be carried over your shoulder while welding in over head position refer Fig 1.
This will help in maintaing the constant distance between the torch and joint to be welded.
Using a welding helmet and wearing a welders overall is very essential to protect the whole body from the spatters
in over head welding position.
Use stringer bead welding technique and follow the same procedure to complete the lap joint.
