Chapter:

26. In an assembly of hole and shaft, largest shaft was having diameter of 50.18 mm and smallest hole was having diameter of 49.98 mm. Maximum interference in mm will be

0.2 0.3 0.3 0.1

0.2

Maximum Interference is difference between size of largest haft size and smallest hole size. Minimum interference is difference between size of smallest shaft and size of biggest hole.

Hint Answer

27. Amount of voltage required to generate arc under no load condition is called?

Open circuit voltage Closed circuit voltage Short circuit voltage Arc voltage

Open circuit voltage

Amount of current required to generate arc under no load condition is called short circuit current (SCC).

Hint Answer

28. The junction between two workpieces and weld face is known as?

Throat Toe Root Puddle

Throat

The throat of a weld is distance from centre of face to root of weld. Typically, depth of throat should be at least as thick as thickness of metal we are welding.

Hint Answer

29. Value of minimum interference is given by

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

Size of smallest shaft – size of biggest hole

Minimum interference is difference between size of smallest shaft and size of biggest hole.

Hint Answer

30. The heavier oxide films are removed by using?

Basic flux Emery Organic solvents Neutral flux

Emery

Oxide films should be removed before welding. Heavier oxide films may be removed by acid pickling, emery or by wire brusing.

Hint Answer

31. Which of following flame is harmful to steel?

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

Oxidizing flame

Oxidizing flame is harmful to steel. An oxidizing flame should not be used for welding steel because deposited metal will be porous, oxidized and brittle. This flame will ruin most metals and should be avoided.

Hint Answer

32. Maximum material limit of shaft is

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

Maximum diameter of shaft

Maximum material limit of shaft is maximum diameter of shaft. Minimum material limit of shaft is minimum diameter of shaft.

Hint Answer

33. The depth up to which, filler material is mixed up with base metal is called?

Deposition Reinforcement Penetration Fusion depth

Penetration

The depth up to which filler material is mixed up with base metal is called as penetration. Penetration can be increased by increasing temperature and appropriate flux.

Hint Answer

34. How does arc voltage V depends upon length of arc L?

V = f(L) V = 1/f(L) V = f(L2) V = f(√L)

V = f(L)

V= A+BL, where ?V? is arc voltage and ?L? is length of arc in cm, A & B are constants.

Hint Answer

35. Which of following does not require fluxes to eliminate oxides present in m?

Mild steel Copper Aluminium Magnesium

Mild steel

Mild steel does not require flux to eliminate oxides, due to fact that iron oxide has relatively low melting point when compared to or non-ferrous metals given.
