An arc-welder creates heat using:
propane |
|
high voltage electricity |
|
oxyacetylene |
|
natural gas |
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.
These tools are called:
files |
|
rasps |
|
chisels |
|
planes |
Wood chisels are used to shape or smooth wood surfaces. They come in a variety of widths and can be used with hand power or tapped with a mallet when deeper cuts need to be made.
Which type of screwdriver has a straight slot in the top?
slotted |
|
phillips |
|
nut driver |
|
hex |
Screwdrivers come in many different handle, shaft, and tip configurations for use in a wide variety of applications. Screwdrivers are classified by their tip which is shaped to fit a corresponding screw head. Common tips are slotted (flat) and Phillips (x-shaped).
Measuring tools provide a convenient and easy way to compare object dimensions against:
each other |
|
perfection |
|
a standard |
|
a drawing |
Measuring tools give easy access to the wide variety of standard dimensions that are used to categorize and classify objects.
The primary difference between a standard level and a bullseye level is which of the following?
a bullseye level has only one bubble to center |
|
a bullseye level can measure across two dimensions |
|
a standard level can measure across two dimensions |
|
a standard level has only one bubble to center |
Levels utlize a fluid-filled tube containing a bubble that is centered when the surface is horizontal (level) or vertical (plumb) along the direction of the tube. While a standard level can measure along a single dimension, a bullseye level is circular and can indicate the levelness of a two dimensional plane.
