Final answer:
Friction welding is employed in the aerospace industry for high-strength joints, boasts high energy efficiency, and incurs low production costs. However, it typically is limited to joining similar materials.option d.
Step-by-step explanation:
Friction welding is a type of solid-state welding process that generates heat through mechanical friction between workpieces in relative motion to one another, with the addition of a lateral force to enable bonding. This technique is widely used in different industries due to its numerous applications and benefits.
Applications of Friction Welding
Aerospace components: Friction welding is extensively used for joining critical parts in the aerospace industry due to its ability to produce high-strength joints.
High energy efficiency: Compared to traditional welding methods, friction welding is more energy-efficient, as it does not require a high-energy input like laser or arc welding.
Low production costs: The process is economical due to faster production rates and minimal material wastage.
Limitations of Friction Welding
Limited to similar materials: Generally, friction welding is used to join similar materials, though advancements allow dissimilar materials to be joined with specialized techniques.
