What to be ensured:-
- Spheriblocks being used in WAP-5 Bogies ( 8 in each bogie) should not be of
expiry date. Being rubber item, it may not be desirable from
residual life point of view.
- Fixtures for bogie fabrication should be calibrated
Welding by GMAW process ( W 25.002):-
What to ensure:-
Lots of spatter which appear after each welding should be avoided.
- The anti-spatter spray should beused by staff without fear of flashing. Anti-spatter spray being used should not be of
