An arc-welder creates heat using:
high voltage electricity |
|
propane |
|
natural gas |
|
oxyacetylene |
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 statements about drill bits is not true?
drill bit size maxes out at ½" for metalworking |
|
drill bit size maxes out at ¼" for woodworking |
|
drill bits are primarily right-handed |
|
drill bits are primarily left-handed |
Drill bits remove material to create holes. They come in a variety of sizes, maxing out at ¼" for woodworking and ½" for metalworking. The majority of drill bits are right-handed which means they cut while rotating in a clockwise direction.
A __________ is driven by a motor and used to shape and form edge contours.
file |
|
router |
|
plane |
|
chisel |

Which of these saws is used with a miter box?
hacksaw |
|
rip saw |
|
crosscut saw |
|
back 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.
This tool is a(n) __________.
adjustable wrench |
|
box-end wrench |
|
combination wrench |
|
open-end wrench |
Wrenches are used to provide grip and mechanical advantage by applying torque to turn objects (or to keep them from turning). The longer the wrench, the more torque that can be applied. Wrench ends are available in two primary types, open-end and box-end. A box-end wrench encloses the bolt head and is useful when more torque is needed or to maintain contact in difficult to reach locations. An open-end wrench is designed for speedily loosening easier to reach fasteners. Wrenches that feature one open and one box end are called combination wrenches and adjustable wrenches feature an open end with an adjustable width.
