Which of the following is not a type of electric-arc welding?
TIG |
|
MIG |
|
stick |
|
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 is used in metal work for shaping metal?
claw hammer |
|
mallet |
|
rivet hammer |
|
ball peen hammer |
Ball peen hammers are most commonly used in automotive repair. They have rounded heads and are used to drive punches and chisels.
You're replacing the hubcaps on a car. Which of the following are you most likely to use?
wooden mallet |
|
rubber mallet |
|
claw hammer |
|
ball-peen 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.
An arc-welder creates heat using:
high voltage electricity |
|
oxyacetylene |
|
propane |
|
natural gas |
