Which of the following statements about welding is not true?
no filler metal is required when welding |
|
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 |
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 would be used to make a drilling guide mark in a sheet of metal?
pin punch |
|
screwdriver |
|
chisel |
|
center punch |
A punch is narrow and is used to drive objects like nails (pin punch) or for making guide marks for drilling (center punch) or patterns in wood or metal.
You need to secure a piece of wood while you're drilling a hole. Which of the following would be the most appropriate tool to use?
pincers |
|
pliers |
|
clamp |
|

You're creating a tube out of a sheet of metal. What type of fastener are you likely to use?
rivet |
|
glue |
|
punch |
|
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.
