Soldering copper joints is commonly known as what?
-
Silvering
-
Sweating
-
Threading
-
Welding
-
None of the above.
Correct Answer
A. SweatingExplanation
Soldering copper joints is commonly known as "sweating" because when soldering, the copper pipes are heated until the solder melts and flows into the joint, creating a strong and secure connection. This process is often referred to as "sweating" because the heat causes the solder to bead and form droplets, resembling sweat.Rate this question:

Preparing a copper joint for soldering includes (mark all that apply):
-
Cleaning the outside of the pipe
-
Cleaning the inside of the pipe
-
Cleaning the outside of the fitting
-
Cleaning the inside of the fitting
-
Applying flux
Correct Answer(s)
A. Cleaning the outside of the pipe
A. Cleaning the inside of the fitting
A. Applying fluxExplanation
To prepare a copper joint for soldering, it is necessary to clean the outside of the pipe to remove any dirt, debris, or oxidation that may hinder the soldering process. Cleaning the inside of the fitting is also important to ensure a proper fit and to remove any contaminants that may interfere with the solder bond. Applying flux is another crucial step as it helps to remove oxidation and promotes the flow of solder, creating a strong and reliable joint.Rate this question:

How far must the pipe must go into the fitting socket in order to ensure that the joint holds?
-
At least 1/4"
-
Half the diameter of the tubing
-
All the way until it "bottoms out" inside the fitting
Correct Answer
A. All the way until it "bottoms out" inside the fittingExplanation
To ensure that the joint holds, the pipe must be inserted all the way until it "bottoms out" inside the fitting. This means that the pipe should be pushed in until it reaches the end of the fitting socket. This ensures a secure and tight connection between the pipe and the fitting, preventing any leaks or disconnections.Rate this question:

Which of the following can be used to ignite a torch (mark all that apply)?
-
Auto-igniter
-
Cigarette lighter
-
Match
-
Striker
Correct Answer(s)
A. Auto-igniter
A. StrikerExplanation
An auto-igniter can be used to ignite a torch because it is designed to create a spark or flame when activated. A striker can also be used to ignite a torch as it is used to strike against a rough surface, creating a spark that can ignite the torch. However, a cigarette lighter and match can also be used to ignite a torch, so they are also correct answers.Rate this question:

How do you know when the copper fitting and tubing are hot enough to apply solder?
-
The solder melts when it touches the joint
-
The copper glows bright red
-
The flux bubbles and hisses
-
You can no longer hold the pipe with your hand
Correct Answer
A. The solder melts when it touches the jointExplanation
When soldering copper fittings and tubing, the solder melts when it touches the joint because the heat from the hot fitting and tubing causes the solder to liquefy. This indicates that the copper fitting and tubing are hot enough to apply solder and create a secure bond.Rate this question:
