Gland Pharma Interview Questions, Process, and Tips

The solder used to join aluminium is typically an aluminium-based solder.

• Aluminium-based solder is commonly used for joining aluminium parts.

• Aluminium solder typically contains a combination of aluminium and other metals such as zinc, tin, or copper.

• The choice of solder depends on the specific application and the desired strength and durability of the joint.

• Examples of aluminium-based solders include Alumiweld, Alumifi

The unit of resistivity is ohm-meter (Ω·m).

• Resistivity is a measure of a material's ability to resist the flow of electric current.

• It is the intrinsic property of a material and is independent of its shape or size.

• Resistivity is denoted by the symbol ρ (rho).

• It is calculated by dividing the resistance of a material by its cross-sectional area and length.

• Common examples of resistivity values: copper - 1.68 × 10^-8 Ω·m, ...read more

The filler material used in brazing is typically a metal alloy that has a lower melting point than the materials being joined.

• Filler materials in brazing are often composed of metals such as silver, copper, or nickel.

• These filler materials are chosen based on their compatibility with the base metals being brazed.

• The filler material is heated to its melting point and then flows into the joint, forming a strong bond when...read more
