11. The chemical formula of acetylene is?

C₂H₄ C₂H₆ C₂H₅OH C₂H₂

C₂H₂

The chemical formula of acetylene is C₂H₂. 1 mole of acetylene can produce KJ/mol of heat.

Hint Answer

12. In which of following joining process, filler material used is same as parent material?

Autogenous Homogenous Heterogenous Either homogenous or heterogenous

Homogenous

In homogenous joining process filler material used is same as parent material.

Hint Answer

13. In which of following type of flame, oxygen is of same proportion with acetylene?

Neutral flame Oxidizing flame Carburizing flame Both oxidizing flame and carburizing flame

Neutral flame

In neutral flame oxygen is in same proportion with acetylene. Neutral welding flames are commonly used to weld: mild steel, stainless steel, cast iron, copper, aluminium, etc.

Hint Answer

14. Value of maximum Interference is given by

Size of smallest hole – size of biggest shaft Largest of shaft size hole – smallest hole size Size of smallest shaft – size of biggest shaft None of the mentioned

Largest of shaft size hole – smallest hole size

Maximum Interference is difference between size of largest haft size and smallest hole size.

Hint Answer

15. For brazing, soldering and flame hardening which of following flame is used?

Neutral flame Oxidizing flame Carburizing flame Both oxidizing flame and carburizing flame

Carburizing flame

For brazing, soldering and flame hardening carburizing flame is used.

Hint Answer

16. In welding, two parts are joined by bringing m to a temperature of?

Above melting point temperature Below melting point temperature Equal to melting point temperature Equal to Curie temperature

Above melting point temperature

In welding one needs to melt base metals to fuse m.

Hint Answer

17. In order to prevent oxidation and retain molten metal in stud welding which of following is used?

Ceramic rings Metal rings Non-metal rings Flux

Ceramic rings

In order to prevent oxidation and retain molten metal in stud welding ceramic rings are used.

Hint Answer

18. Maximum material limit of hole is

Maximum diameter of hole Maximum diameter of shaft Smallest diameter of hole Minimum diameter of shaft

Smallest diameter of hole

Maximum material limit of hole is smallest diameter of hole. Minimum material limit of hole is largest diameter of hole.

Hint Answer

19. What is function of flux in submerged arc welding?

To completely cover the welded zone To prevent oxidation of joint To prevent spattering of molten metal To prevent sticking of molten metal

To prevent sticking of molten metal

Flux is used to completely cover welded zone. It prevents oxidation of weld joint and spattering of molten metal.

Hint Answer

20. What is function of a torch?

It controls fuel rate It mixes fuel and oxygen and controls delivery It controls oxygen rate It mixes fuel and hydrogen

It mixes fuel and oxygen and controls delivery

Torch mixes fuel and oxygen and controls delivery. It has two control valves, one for controlling flow of acetylene and or of oxygen, entering a chamber called mixing chamber where two gases are mixed in a correct proportion.
