Q2. Which gas can use for while hot/live tapping
Ans. 
Nitrogen gas is commonly used for hot/live tapping in mechanical engineering.
• Nitrogen gas is inert and non-reactive, making it safe to use in hot/live tapping processes.

• It helps to create a protective atmosphere to prevent explosions or fires.

• Nitrogen gas is readily available and cost-effective.

• Other gases like argon or carbon dioxide can also be used depending on the specific requirements.

Q6. Explain About RT, UT, and magnetic partials
Ans. 
RT, UT, and magnetic partials are non-destructive testing methods used in engineering.
• RT stands for Radiographic Testing and uses X-rays or gamma rays to inspect the internal structure of a material.

• UT stands for Ultrasonic Testing and uses high-frequency sound waves to detect flaws or defects in a material.

• Magnetic particle testing uses magnetic fields and iron particles to detect surface and slightly subsurface defec...read more

Q3. What is eutectic point?
Ans. 
Eutectic point is the temperature at which a eutectic mixture solidifies or melts at a constant temperature.
• Eutectic point is the lowest possible melting point of a mixture of two or more substances.

• It is a specific composition of a mixture where the melting point is at its lowest.

• At the eutectic point, the mixture solidifies or melts at a constant temperature.

• Examples of eutectic mixtures include solder, alloys, and c

Q4. What is eutectoid point?
Ans. 
Eutectoid point is the temperature at which a eutectoid reaction occurs.
• Eutectoid point is a specific temperature at which a solid solution transforms into two or more different solid phases.

• It is a characteristic property of alloys.

• For example, the eutectoid point of steel is 727°C, at which austenite transforms into pearlite.

• Eutectoid point is important in the heat treatment of metals and alloys.

Q5. What is pearlite and how does its form? is it ductile? if yes why?
Ans. 
Pearlite is a lamellar mixture of ferrite and cementite formed during slow cooling of austenite.
• Pearlite is a microstructure commonly found in steels.

• It is formed during the eutectoid reaction when austenite transforms into ferrite and cementite.

• It has a layered structure which gives it good ductility.

• Pearlite is not a separate phase but a mixture of two phases - ferrite and cementite.

• It is commonly used in the manufac...read more
