Which of the following statements about welding is not true?
electric-arc welding is safer than oxyacetylene welding |
|
welding is done at higher temperatures than soldering |
|
a weld can often be stronger than the base materials alone |
|
no filler metal is required when 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.
You're creating a tube out of a sheet of metal. What type of fastener are you likely to use?
punch |
|
rivet |
|
glue |
|
nail |
A nail is a short pin-shaped shaft of steel that's typically used to fasten pieces of wood together. It has a flat head on one end and a point on the other. A rivet consists of a cylindrical shaft with a head on one end and a tail on the other. When the rivet is installed, the tail is expanded and reshaped to form another head, creating a dumbell shape that will hold two surfaces together semi-permanently.
You're replacing the hubcaps on a car. Which of the following are you most likely to use?
wooden mallet |
|
rubber mallet |
|
ball-peen hammer |
|
claw hammer |
A mallet is a hammer with a relatively large head, often made of rubber or wood. Both the size and material of the mallet head help prevent damage when striking more delicate surfaces.
Which of these saws is used with a miter box?
crosscut saw |
|
hacksaw |
|
back saw |
|
rip saw |
A miter box utlizes a back saw (a fine toothed saw with a rigid strip of steel opposite its blade edge) to make cuts in wood at a specified angle.
