What happens when solder flows?

If you're soldering an L-shaped piece, for instance, and you don't reach the solder flow temperatures on both pieces of metal, the solder will flow onto the hottest one. Make sure both pieces of metal are equally heated or you'll have a puddle of solder on only one side.

Why does solder flow?

Heat is the number one reason that solder flows. Without it, you'll unsuccessfully try to solder a piece for a very long time. Heat is a tricky thing to figure out, especially if you're just starting out.

What to do if you forget flux?

If you forget your flux, drop your whole piece in the pickle to clean off the firescale, add the flux, try it again and this time it should flow just fine. Remember: flux is your friend. It reduces firescale and helps the solder flow. 2. Oil, Grime, and Dirt. Clean Dirt & Oil Off Before Soldering. Don't forget to clean your pieces before soldering.

What draws heat away from jewelry?

There is a good chance that you have something else drawing your heat away from where you need it. Anything like a steel tripod mesh or a third hand can draw heat away from your jewelry piece, which is called a "heat sink". As you heat your piece up, that steel item is pulling that heat away just as quickly.

How to solder a 3rd hand?

If you're using a third hand, try to place just the corner of your piece in it. Just enough to hold it, but not to pull a lot of heat from it. If it's still not working, consider a charcoal block which reflects heat, making it easier to solder.

How to remove oil from soldering?

Don't forget to clean your pieces before soldering. A light sanding with an 800 grit sandpaper will remove oil left behind from your fingerprints plus grease and dirt, as well. Just remember, don't touch where you've just sanded it or you will need to do it over again.

Also available are Silver bearing Copper Phosphorus Alloys (CoPhos). These are available with either 2% or 5% Silver and are used primarily for joining Copper to Copper, where, if the metal is clean, no Flux need be used.

Can you join two pieces of thin sheet metal together?

So if, for example, you want to join two pieces of thin sheet metal together, you would need to overlap them. The Silver Solder will be drawn through the joint, filling the minute crack between the two pieces of metal, bonding with the surfaces to join them.

Is flux coated wire cheaper than bare wire?

Flux coated wires are more expensive than bare wire. If you need additional flux, you’ll still need a pot of powder. If the wires are bent, the flux tends to fall off! Flux Impregnated – (Braze Only). Here the flux is in little nicks on the wire. This works very well and the wires can be bent.

Why is flux better than solder?

Flux enables a better flow of solder. This has many advantages. Having a better flow of solder means having to use less solder. Using less solder has the added benefit of lowering your cost as you will be using and buying less solder. Also, soldering at lower temperatures, solder does not melt, flow and adhere well.

What is flux solder?

Flux is a water based solution that contains a cleaning agent, activator and wetting agent. It has many functions that are used when soldering. It has to spread on the metals being soldered, it has to clean the surfaces and help spread the solder. For a flux to be effective it has to satisfy all these three criteria.

What is soldering iron?

How is solder size determined?

The size of the solder is determined by its gauge. The gauge is effectively determined by its diameter. Different gauges of solder will be beneficial depending on the application. When it comes to electronics work, the smaller the gauge size the better.

Why do you need flux for solder joints?

Without this, a solder joint will not be strong or conductive enough. One of the other reasons that you need flux is that the solder will chase a heat source.

What is the best alternative to flux for soldering?

The best alternative to flux when soldering is petroleum jelly which is anti-corrosive and will not damage your material.

What is rosin flux?

This type of flux is commonly known as rosin. There are also other organic fluxes made with citric and lactic acids. Several inorganic fluxes are used for more industrial applications. Strong metals such as brass and copper will require a synthetic acid flux in order to be soldered.

How to make pinecone flux?

Pinecone flux can be made with 10-15 pinecones and some denatured ethyl alcohol. The natural pine tar in the cone leaves works as a flux and can be extracted. Cut the cone leaves and place them in a container, then pour the alcohol over the leaves and let them sit overnight.

What is flux made of?

A flux clears these oxides and gives you a perfectly flat surface. Most modern organic fluxes are made of purified and refined pine sap. This is the oldest type and continues to be used to this day.

How to make acid flux?

To make a lemon juice flux, cut 6 lemons in half and juice them. Strain the juice with a juice strainer and stir it for 20 seconds. Then , strain it again and stir it for another 20 seconds. It should be noted that you should not refrigerate this flux.

Does acid core solder clean metal?

The solder will clean the surface as it melts. Acid core solder will also clear metal surfaces of oxides as well as corrosive by-products. The acid acts as a flux and is able to clean as it adheres. Because of this, it is recommended for strong metals like brass, steel, and copper.
