Which of the following statements about solding is not true?

56% Answer Correctly

solder is an alloy of lead and tin

flux is used to clean surfaces before soldering

soldering can only join metals

solder has a comparatively low melting point


Solution

Soldering is a process by which two or more items (typically metal) are joined together by melting a filler metal (solder) into the joint. An electrically powered soldering iron or soldering gun is used to melt the solder which is an alloy of lead and tin that has a melting point below the melting point of the items being joined. A chemical cleaning agent called flux is also used to clean the surfaces before soldering.


2

Which of these saws is used with a miter box?

56% Answer Correctly

rip saw

crosscut saw

hacksaw

back saw


Solution

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.


3

Which of the following statements about welding is not true?

63% Answer Correctly

welding is done at higher temperatures than soldering

electric-arc welding is safer than oxyacetylene welding

a weld can often be stronger than the base materials alone

no filler metal is required when welding


Solution

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.


4

You're replacing the hubcaps on a car. Which of the following are you most likely to use?

74% Answer Correctly

claw hammer

rubber mallet

ball-peen hammer

wooden mallet


Solution

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.


5

Screwdrivers are most broadly classified by their:

91% Answer Correctly

tip

width

torque

length


Solution

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).
