1
The casting method adopted for ornaments and toys of nonferrous alloys, is
Discuss
Answer & Solution
Answer: Option B
Solution:
Slush Casting is a traditional method of permanent mold casting process, where the molten metal is not allowed to completely solidify in the mold. When the desired thickness in obtained, the remaining molten metal in poured out.
2
The tolerance produced by shell moulding process of casting is
Discuss
Answer & Solution
Answer: Option B
Solution:
The tolerance produced by shell moulding process of casting is ±0.2 mm
3
In order to get uniform thickness of the plate by rolling process, one provides
Discuss
Answer & Solution
Answer: Option A
No explanation is given for this question. Let's Discuss on Board
4
The operation of straightening a curved sheet metal, is known as
Discuss
Answer & Solution
Answer: Option D
Solution:
The operation of straightening a curved sheet metal, is known as Planishing
5
The operation of producing cup shaped parts from flat sheet metal blanks by bending and plastic flow of metal, is known as
Discuss
Answer & Solution
Answer: Option A
Solution:
The operation of producing cup shaped parts from flat sheet metal blanks by bending and plastic flow of metal, is known as Drawing
6
Extrusion
Discuss
Answer & Solution
Answer: Option D
Solution:
Extrusion is a process used to create objects of a fixed cross-sectional profile. A material is pushed through a die of the desired cross-section.
Extrusion is Consists of pressing the metal inside a chamber to force it out by high pressure through an orifice which is shaped to provide the desired form of the finished part.
7
Cold working of metal increases
Discuss
Answer & Solution
Answer: Option D
Solution:
An example of desirable work hardening is that which occurs in metalworking processes that intentionally induce plastic deformation to exact a shape change. These processes are known as cold working or cold forming processes.
The cold working of the metal increases the hardness, yield strength and tensile strength.
8
The process used to improve fatigue resistance of the metal by setting up compressive stresses in its surface, is known as
Discuss
Answer & Solution
Answer: Option C
Solution:
The process used to improve fatigue resistance of the metal by setting up compressive stresses in its surface, is known as Cold peening
9
For arc welding
Discuss
Answer & Solution
Answer: Option C
Solution:
Arc welding is a welding process that is used to join metal to metal by using electricity to create enough heat to melt metal, and the melted metals when cool result in a binding of the metals.
For arc welding direct current is used.
10
In backhand welding, the angle between the welding rod and the work is ________ as compared to forehand welding.
Discuss
Answer & Solution
Answer: Option C
Solution:
In welding, the terms "forehand" and "backhand" refer to the direction and angle at which the welding torch or rod is held relative to the direction of welding.

In forehand welding, the welding rod is directed in the direction of welding with a smaller angle (typically around 30° to 45°) between the rod and the workpiece.

In backhand welding, the rod is directed opposite to the direction of welding, resulting in a greater angle (typically around 45° to 70°) between the rod and the workpiece.

This greater angle in backhand welding allows better penetration and is often used for thicker materials.

Therefore, the angle between the welding rod and the work is more in backhand welding as compared to forehand welding.
