5. STUDY OF “FRAME WELDING”
 In manufacture of three
wheeler frame (chassis) various
type of process are used. some
following process are given
below :-
a) Material selection
b) Cutting/machining
c) Welding
d) Painting etc.

6. MATERIAL SELECTION
 Generally we used to
I,C,L – section metal
gurdder (Iorn beam) in
manufacturing of
chassis.
 But in SIL, C – SECTION
material are used mainly.
 Other clamping parts are
used iorm metal.
 Hallow cylinder metal
pipe also be used.

7. CUTTING/MACHING
 After selecting of material
cutting process will be done. In
this process C –sec beam cut on
given ranges with the menual &
automated machines.
 Surface finishing process are
done on this objects because
they have very rough surface and
removing of tolerances error on
their dimensions.

8. Welding proces
 In frame welding mainly
used to following type of
weldings :-
 MIG WELDING
 SPOT WELDING
 GAS WELDING

9. USING OF MIG IN CHASSIS
 In Scooter India ltd. using of MIG welding in three
wheeler frame because :-
 All position capability.
 Higher deposition rates.
 Long welds can be made without starts and stpos.
 Minimal post cleaning is required.

10. PROCEDURE :-
 After all process object set
on the rotating table and a
skilled welder joint the
chassis component with
MIG welding.
