True or false. The 'Parent' metal is the metal being joined and the 'filler' metal is the metal that will be melted into the join.
True
False
What makes soldering different from welding? Pick one.
Nothing, they are both the same
Soldering melts the two parent metals together, welding does not.

You use different filler metal to the parent metal in welding.
True or false. Welding uses a filler metal that is similar to the parent metals. (ie those being welded)
True
False
Tick all of the features of soldering
High temperature
Uses low melting point filler metals around 450 deg melting point
Stronger than welding
Flux must be used.
Different parent metals can be joined.
Tick all the correct statements about gas welding.
It uses electricity to make the join.
We burn acetylene and oxygen to create the heat for joining.
The filler rod must be the same as the parent metal.
Two parent metals must be similar.
Uses low temperature.
What do the letters MIG stand for when welding?

Metal in Gas
Tick all of the correct statements about MIG welding.
An inert gas is used to shield the weld.
Disimilar parent metals can be joined
A single filler rod is used
A continuously fed filler rod is used.
It uses electricity to create the heat.
Why is gas used in MIG welding. Pick one
To help melt the metal
To keep the weld clean and strong by shielding the weld from contaminants in the air.
To burn and help the weld
Spot welding is used to weld car body panels together. Tick all statements that are true.
It uses electricity and pressure to melt and force the metal layers together.
A filler metal is used
