A welding rod provides:
stability for the welding torch |
|
fuel for the welding torch |
|
the joining material for a weld |
|

The joining material for a weld is called a welding or filler rod and is available in a variety of diameters and alloys for different welding tasks.
Which of the following statements about an 8-point saw is not true?
an 8-point saw makes a rougher cut than a 6-point saw |
|
an 8-point saw makes a rougher cut than a 12-point saw |
|
an 8-point saw has eight teeth per inch |
|
an 8-point saw makes a finer cut than a 12-point saw |
Saw blades are described by the number of teeth per inch (TPI). The higher the TPI of a saw the finer the cut it will make.
What is a caliper used for?
ensuring that surfaces are level |
|
transferring distances between objects |
|
measuring thickness and irregular shapes |
|
making perfectly vertical lines |
Calipers are similar to micrometers in shape but instead of measuring distances, calipers are used to transfer distances between objects. An outside caliper is used to transfer outside dimensions while an inside caliper is used to transfer inside distances. A vernier caliper is an extremely precise caliper (down to \({1 \over 1000}\) inch) that allows measuring / transferring either inside or outside dimensions.
Which of the following saws is not good for cutting wood?
ripsaw |
|
crosscut saw |
|
back saw |
|
hacksaw |
A hacksaw has replaceable blades and is used to cut metal. The blade type is chosen based on the material that is to be cut. Blades with larger numbers of teeth per inch are more appropriate for cutting thinner materials.
What is a framing square used for?
measuring length around corners |
|
ensuring that surfaces are level |
|
marking lines at a right angle |
|
measuring thickness and irregular shapes |
Rulers are used to both measure distance and to draw straight lines. Tape measures are flexible rulers made from cloth or metal and are useful for measuring longer distances and in tighter spaces. Both rulers and tape measures provide similar accuracy, commonly down to \({1 \over 16}\) or \({1 \over 32}\) inch. A steel framing square is made up of a shorter ruler (tongue) and a longer ruler (blade) that meet at a 90° (right) angle. A framing square is often used by carpenters when framing stairs and roofs.
