SGT University Interview Questions and Answers

The current ingot price, conversion cost of furnace, suppliers for ingot and billets, and density of Aluminium are key factors in operations and supply chain management.

• Current ingot price is a crucial factor in determining the cost of raw materials for production.

• Conversion cost of furnace includes expenses related to melting and shaping the ingots into usable forms.

• Identifying reliable suppliers for ingot and billets is essential for ensuring a steady supply chain.

• Density o...read more

The least count of vernier calliper is the smallest measurement that can be read on the scale.

• The least count is determined by the number of divisions on the vernier scale and the main scale.

• It is usually 0.02 mm or 0.05 mm for a standard vernier calliper.

• The least count can be calculated using the formula: (1 main scale division) / (number of divisions on the vernier scale).

The least count of micrometer is the smallest measurement that can be read on the micrometer scale.

• The least count of micrometer is typically 0.01 mm or 0.001 cm.

• It can be calculated by dividing the pitch of the screw by the number of divisions on the thimble.

• For example, if the pitch is 0.5 mm and there are 50 divisions on the thimble, the least count would be 0.01 mm.

• The least count is important for accurate measurements and should be considered when using a micrometer.

Aluminium alloys like 6063, 6005, 6083 have different chemical compositions for specific properties.

• 6063 alloy: Contains magnesium and silicon, good for extrusion applications.

• 6005 alloy: Contains silicon and magnesium, offers good formability and weldability.

• 6083 alloy: Contains magnesium and silicon, provides high strength and corrosion resistance.

Alloys are mixtures of metals with specific properties. Some common types include stainless steel, bronze, and brass.

• Stainless steel - major alloy element is chromium

• Bronze - major alloy element is copper

• Brass - major alloy element is zinc
