Hai friendsâ¦â¦ This is RAMPRASADâ¦..I am written the senior technical assistanceâ Aâ on METALLURGY (Diploma Based exam on 9/03/2008). In exam most of the questions from the p.p.m, thermo dynamics, physical metallurgy, iron making, heat treatment, foundary technology, nonferrous. Less questions from fuels &refractory, steel making, welding, material testing, mechanical metallurgy.
I am written some question( I am not written total question) and answers(only some ans) . Questions are asked only fundamentals. I think exam is very easy for fresher candates.
EXAM PATTERN:
