SpotWelding...
In Spot Welding the pieces to be joined are
clamped between two electrodes under force,
and an electrical current is sent through them.
Force is applied before, during, and after
the application of current to prevent arcing at
the work piece.
In spot welding fusion of faying surfaces of alap joint is achieved at one location by
opposing electrodes

Advantages ofSpot Welding
Spot welding is quick and easy
No need to use any fluxes or filler metal
Multiple sheets joined together at the same time.
No dangerous open flame
Saves production costs.

Projection Welding
In Projection welding size and shape of individual
welds are determined by the presence of projections,
embossments or intersections on the metals to be
joined.
Metals are heated and coalescence is achieved notthrough the use of an arc, but through the metals
resistance to electrical currents passing through them
as they are held together with pressure by electrodes.
In projection welding the pieces to be joined areclamped between two electrodes under force, ananelectrical current is sent through them.

Advantages ofProjection Welding
Simultaneously we can make
any number of welds in heavier
materials easily.
Welding can be made in metals
that are too thick to be joined byspot welding.
Lower Electrode Maintenance.
Lower amount of current andpressure needs to joint metals.
Faster and Quicker and used in
mass production
