Why does my solder ball up?

Why does my solder ball up?

Balling is caused by bad wetting. Make sure the iron temperature is correct; too hot and it causes quick oxidation of the tip and the balling effect. Clean the tip before applying solder using a wire cleaner or chemical cleaner. The solder will wet much better then.

How do you prevent soldering balls?

Ways to prevent solder balls from being created Ensure that the board is properly dried or preheated (to evaporate trace water amounts) before printing. Clean the printing stencil properly before application of solder paste. Ensure flux is applied in proper amounts to prevent excessive air/water from trapping.

Why is the solder not melting?

If it’s not melting the solder, then the iron is not hot enough or even working. Try poking the tip through a piece of paper. The thicker solder requires more heat to melt. 40W is relatively low power, for thin solder it should work fine though.

Can you use Vaseline instead of flux?

The answer is yes. Using petroleum jelly as a soldering flux is an effective soldering flux alternative.

What can I use instead of flux to solder?

It is possible to solder without flux but you must use something to help break down the oxides on metal surfaces. Most modern solder is made with a rosin core that acts as a built-in flux. If your solder does not have this, you can also use petroleum jelly.

What can I use if I don’t have solder?

Steel wire, screwdrivers, nails, and Alan wrenches are all potential tools for your emergency soldering. Just heat your wire or other steel tool over some open flame for 20-30 seconds and then proceed to solder as you normally would.

Can I use aluminum foil instead of solder?

Aluminium kitchen foil is very thin and will melt, as in a fuse, at a fairly low current. Again solder would ne unsuitable as it is compounded to melt at a low temperature and would blow at a much lower current than proper fuse wire.

Can I use glue instead of solder?

As others have said super glue is not conductive. You can buy conductive adhesive which is used when normal soldering is not practical. It is an option when a normal solder job can’t be done. It is not as good as solder for many reasons but it can be very useful if soldering can not be done normally.

Can you use too much solder on copper pipe?

Use the proper amount of solder Don’t feed too much solder into the joint. It’s tempting to melt a few inches of solder into a joint as extra insurance against leaking. But excess solder can puddle inside pipes, restricting water flow, and can form small balls that break loose and damage faucet valves.

Do you need special solder for copper?

Learn the different types of copper pipe as you prepare. As you’ll see, you don’t need special skills for soldering copper pipe fittings successfully. You can easily solder a leakfree copper solder joint on the first try—but you can also make mistakes.

What solder do plumbers use?

Electrical solder is commonly a 60/40 blend of lead and tin. Because of the dangers of toxic lead in drinking water, local building codes now legally require the use of lead-free plumbing solder on all potable water plumbing connections that require soldering.

Can you solder over old solder?

It must be disassembled, cleaned, fluxed, and soldered. It can not be done by just adding more solder.

Can plumbing solder go bad?

No, it can’t go bad. A properly done solder joint will last the lifetime of the piping. Sometimes you get a cold solder joint in which the two pieces of the joint do not bond(usually caused by bad preparation) but it seems to seal for a while then starts leaking. If it looks clean it is good.

Can you overheat a solder joint?

Don’t overheat the flux If you heat the joint too long, you’ll burn the flux (it’ll smoke and turn black) and make it difficult to get the solder to flow into the joint.

How do you fix a bad copper solder joint?

Dry the outside of the elbow and sand (120-grit paper or cloth) around the leaking joint to remove all surface corrosion. Apply soldering flux around the whole joint and apply heat with a torch until the old solder melts. Add new solder until a shiny ring of solder shows all around the joint.

Can solder joints fail?

The only way a joint can fail is if it is not made properly, whether it is because the solder did not flow properly or the pipe was not inserted all the way into a fitting. It has nothing to do with turbulence because the solder does not interact with the liquid flow.

How can you tell if a solder joint is bad?

the solder should be shiny after it hardens. If it has gone bad it will stand around on street corners, smoking cigarettes and making weird sucking sounds at female passersby. Another sign of a bad solder joint is if the solder is dull after it hardens, this is what happens with a “cold” joint.

How can you tell if solder is dry?

You’ll see hundreds of little shiny dots with pins sticking out of them. A good solder joint looks nice and shiny whereas failing or ‘dry’ solder joint looks dull and crusty. You might even see a ring or crack around the pin or leg.

Is it hard to solder?

Soldering is a process somewhat like gluing, in that the solder has to form a tight bond between the parts. Just as clean parts glue better, they also solder better. Any mud, blood, beer, grease, oil, or especially oxidation will make the joint difficult or impossible to solder well.

Why is my solder turning black?

Tinning gives longer tip life Iron, however, tends to oxidize rapidly. When oxidation occurs, the tip becomes covered with a black or brown scale, which will not wet with solder – greatly reducing heat transfer. This is commonly known as “burn-out”.

How do you clean the tip of a soldering gun?

Cleaning Options Wiping the iron tip on a damp sponge can help to remove oxides easier, and allows waste to fall away. A Dry Cleaner (special brass wool) can also be used. It consists of soft metal shavings that are coated with flux. You clean the tip by thrusting the iron into the shaving a few times.
