The differential is a component in a vehicle that allows the wheels to rotate at different speeds.

• It helps with turning by allowing the outside wheel to rotate faster than the inside wheel.

• It also helps with traction by allowing the wheel with the most grip to receive more power.

• Without a differential, the wheels would be locked together and unable to rotate at different speeds.

• Examples of vehicles that use differentia

Defects in welding section can include porosity, lack of fusion, undercutting, and distortion.

• Porosity: Formation of small cavities or voids in the weld metal due to trapped gas.

• Lack of fusion: Incomplete bonding between the weld metal and base metal.
