Q

What is riveting

A

Permanent joining method usually used to join sheet metal or plate
Uses rivets which are metal fasteners which have a head at one end and a shaft or tail at the other

17
Q

How does riveting work

A

The rivet is dropped into a pre drilled hole

A set tool is put over the head and the shaft end is hammered to squeeze the two metal together

18
Q

What is pop riveting

A

More modern form of riveting used to join thin sheet metal

19
Q

What is the pop riveting process

A

Rivet used has a rivet and pin and the head is pushed through a hole
Riveting pliers pull out the pin which causes the head to squash down which pulls the two metal together
