Joining Processes Quiz

Which joining process is commonly used in electronics to connect components to circuit boards?

• Welding

• Soldering

• Sanding

• Polishing

What does rapid prototyping involve?

• Removing material from a block

• Adding materials layer by layer

• Molding materials into shape

• Cutting materials into pieces

What is the most common type of rapid prototyping, which heats a filament, usually plastic, to just above its melting point and fuses it layer by layer?

• SLA

• SLS

• FDM

• CNC

What materials can welding be used for besides metals?

• Wood

• Thermoplastics

• Glass

• Ceramics

Which welding method uses a non-consumable electrode?

• MIG welding

• Stick welding

• TIG welding

• Gas welding

What metals are typically used in solder?

• Copper and zinc

• Tin and lead

• Iron and nickel

• Silver and gold

What does soldering primarily rely on?

• Melting the metals it joins

• Melting just the solder

• Freezing the metals

• Gluing the metals

Why must the metals be cleaned well before brazing?

• To change their color

• To keep the mechanical properties intact

• To increase their weight

• To make them shiny

Which of these is NOT an advantage of adhesives?

• Most adhesives are self-curing

• Adhesive bonds are stronger than many other joining processes

• Adhesives bonds are more versatile than many other joining processes

• Adhesives typically do not change the properties of the materials they bond

What category of manufacturing process is mechanical joining typically considered to be?

• A forming process

• A molding process

• A finishing process

• A separating process
