Weiding Vs Riveting

Question 1

What is threaded fastenings

Answer 1

Products such as screws,nuts and bolts that can be used to make a temporary joint

Question 2

What is a rivet

Answer 2

a short metal pin or bolt for holding together two plates of metal, its headless end being beaten out or pressed down when in place.

Question 3

What is rivets used for

Answer 3

Rivets are used to hold sheets of metal , polymer or different materials together.

Question 4

How are rivets used

Answer 4

A hole is drilled in overlapping sheets of material , though which the rivets is inserted. The ends are then hammered over to hold the sheets in place. Rivets need access to both sides of the joints

Question 5

What is soldering

Answer 5

A joining process where metals parts are attached together using a filler wire which melts and runs between them,typically melted using a soldering iron

Question 6

What is brazing

Answer 6

A joining process where metals parts are attached together using a filler wire which melts and runs between them,with heat provided by either a flame or oven

Question 7

What is the process of brazing

Answer 7

• Brazing joins metal part together using filer wire
• the surface to be joined is first cleaned of oxides and rust,paint and grease. A flux is applied to prevent oxidation n
• The joint is then heated to 450-1200 C , typically using a gas flame. The filler metal melts and flows into joint
• it is then allowed to cool and harden

Question 8

What is welding

Answer 8

A joining process for metal parts where the edges of the parts are melted and form the joint , with additional filler metal if needed

Question 9

What is the difference between welding and brazing

Answer 9

The main difference is that welding melts the base metals to fuse them together, while brazing joins them by melting a filler metal that is lower in melting point than the base metals
