Which of the following statements about welding is not true?
no filler metal is required when welding |
|
welding is done at higher temperatures than soldering |
|
a weld can often be stronger than the base materials alone |
|
electric-arc welding is safer than oxyacetylene welding |
Welding is a high-temperature process that involves melting the base metals in the objects to be joined to fuse them together. A filler metal is used to provide additional material to make up a joint that, depending on the weld type, can be stronger than the base materials alone. Oxyacetylene welding is a welding process that uses a torch fueled with oxygen and acetylene gases. Electric-arc welding utlizes electric current in a safer welding process (it doesn't involve burning explosive gases) that enables a wide variety of specialized applications like stick, MIG (metal inert gas), and TIG (tungsten inert gas) welding.
Which of the following saws would you use if you're cutting wood along the grain?
hacksaw |
|
ripsaw |
|
crosscut saw |
|
back saw |
The ripsaw delivers maximum efficiency at cutting with or along the grain (ripping).
When using a hacksaw, blades with __________ teeth are more appropriate for cutting thinner materials.
thinner |
|
wider |
|
less |
|
more |
A hacksaw has replaceable blades and is used to cut metal. The blade type is chosen based on the material that is to be cut. Blades with larger numbers of teeth per inch are more appropriate for cutting thinner materials.
When cutting hard metals with a hacksaw you should choose a blade with __________ teeth per inch (TPI).
low |
|
odd |
|
even |
|
high |
Blades with more and smaller teeth (high TPI) cut harder metals more effectively while blades with fewer and larger teeth (low TPI) cut softer metals more effectively.
You're constructing a cabinet in your workshop and one of the cabinet doors is slightly too big. Which of the following tools would you use to make it fit?
plane |
|
chisel |
|
drill |
|
file |
In wooodworking, a plane is used to shave off a small amount of material to smooth a surface or make it fit properly. A jack plane is a general purpose plane that contains an adjustable depth blade set at an angle with a handle and knob to allow gripping when sliding the plane across wood.
