A: Clean the parts of oxidation first using fluxes.TIN the parts first using fluxes the solder joint should have a solder shine. Make sure there is a good mechanical connection.
If you soldering copper tubing to a fittings tinning first is wrong as it inhibits capillary action and use non acid type of flux is highly recommended

Just had an extension done and your toilet pipe goes through the conservatory but it's not one whole pipe and has a connector in the middle it is firmly together but is this going to be ok as you are?
If the installer is a Master plumber or at least a journeyman and knows how to make a soldered / lead wiped CUP Joint then it should last over 100 years BUT if they did not lead wipe or soldered then your guess is as good as mine.
What should be prevented prior to the solder cooling in order to to get a good shiny solder joint?
Movement. The components being soldered need to be fixed, stable, and clean to allow the solder joint to solidify and adhere properly. Movement of components will cause a 'dry' joint which will be electrically unreliable and have a dull appearance.
What is the appearance of a properly soldered connection?
A properly soldered connection should have a smooth, shiny surface with a uniform, concave shape, indicating good wetting of the solder to both the component lead and the PCB pad. There should be no cracks, gaps, or excessive solder, and the joint should appear solid and well-formed. Additionally, the solder should not have a dull or grainy appearance, which can suggest overheating or insufficient soldering technique. Overall, the joint should look neat and professional.
How do you solder a joint?
To solder a joint, first, ensure the surfaces to be joined are clean and free of oxidation. Heat the joint with a soldering iron until it reaches the appropriate temperature, then apply solder to the joint, allowing it to flow and fill the gap. Remove the heat and let the joint cool naturally to form a solid bond. Finally, inspect the joint for a smooth, shiny finish to ensure a good connection.

What is the purpose of solder flux?
Very simply flux reacts with surface corrosion and washes it away, making the metal surface being soldered easier for the solder to wet and producing a more solid and reliable joint, both mechanically and electrically. Acid flux is more aggressive and acts faster than rosin flux, but must be washed off completely with water as soon as the joint cools because the acid will slowly attack the metal of the joint. As electronic circuits usually should not be washed with water, only rosin flux should be used on electronics because it can be left on the completed joint without damaging it.
With regard to soldering what are the origins of the phrase tin-the-leads?
Tinning is a process of coating leads or other component parts with solder before making a soldered joint. It is done to ensure that the surfaces to be joined will have a good adhesion to the solder to ensure a robust and secure joint. If leads are not tinned before hand, there is a risk of a dry joint - a joint that might appear to be good but in fact does not have solder in intimate contact with the component. Most dry joints have an appearance that exposes the fault but not all do. The term tinning is used as tin is a component of solder (traditional solder is a mix of tin and lead). Tinning now usually means applying solder as described above but it can also mean applying a coating of tin without lead. Using pure tin is rarely if ever used today. Worldwide there is a move to eliminate lead from electronic assemblies and so tin/lead solder is being replaced. Tin is still used but mixed with copper, silver, zing and other more exotic metals. The process of tinning still takes place even with the new lead free solders.
Why is copper used for soldering iron?
Copper is used for soldering iron tips because it has good thermal conductivity, allowing it to quickly transfer heat from the iron to the soldered joint. Additionally, copper is durable and resistant to corrosion, making it suitable for prolonged use in soldering applications.
What are some good solitary sports for someone looking to strengthen their joints?
Some of the best joint strengthening activities can be done either in a group or by oneself.One good example is hiking.
What is cold flow?
It is a term used when soldering with a soldering iron. It means that the solder is not completely up to temperature to make a proper joint. A good solder joint is very silvery in colour and shines when it is done right.
What precautions should be observed when soldering a printed circuit board?
Mainly solder in as short a time as possible to avoid burning the traces causing them to lift. This means using a good quality temperature regulated iron that does not cool off when applied to the joint to be soldered and is not too hot either.
What are the requirements of a good joint in an conductor?
A good joint in a conductor should ensure electrical continuity, mechanical strength, and insulation resistance. It should also be made with appropriate materials for the application and be securely connected without any loose or exposed parts. Additionally, the joint should be properly insulated to prevent any electrical faults or short circuits.
