[#2] The nature of submerged arc welding flux with basicity index of 0.5 is
Correct Answer
(D) acidic
[#3] Lap joints are preferred over butt joints in soldering/brazing because
Correct Answer
(D) the lap joints are easily made
[#4] For a good quality brazing, the molten filler alloy should have
Correct Answer

[#5] Determine the correctness or otherwise of the following Assertion [a] and the Reason [r] . Assertion: In a pure metal weld, elastic modulus in the heat affected zone (HAZ) is the same as that in the base metal. Reason: Coarse grained microstructure in the HAZ results in lower hardness.
Correct Answer
(B) Both [a] and [r] are true and [r] is not the correct reason for [a]
