Explain FIVE (5) justification with examples for coating an engineeringcomponent with ceramics(b) In a certain welding operation, the system can produce welding heat capable oftransferring 2.7 kW to the surface of a metal part. It is observed that the heated areais circular. It is further observed that the heat intensity decreases with increasingradius in which 50% of the power is transferred within a circle of diameter 2.54mm while 75 % is transferred within a concentric circle of diameter of 6.35 mm.
(i) Determine the power densities in the 2.54 mm diameter inner circle.(ii) Determine the power densities in the 6.35 mm diameter ring that lies around the inner circle.(iii) Analyze the power densities in Q5b (i & ii) for sufficiency in melting themetal.
Explain how heat treatment is applied in welding processes and what its importance is.
