What removes excess solder?

Quote from the video:
Quote from Youtube video: Again many of you guys have maybe seen those little solder suckers that take a little spring-loaded pen. So you'll you'll hold those next to your solder.

How do you remove sweat solder?

Quote from the video:
Quote from Youtube video: So start eating the fitting. And use a pair of adjustable pliers to wiggle it off a little tip here is to remove your pliers from the fitting as you're heating they'll absorb the heat.

Can you reuse a soldered fitting?

Copper pipes are usually connected together using a variety of fittings, including elbows, T’s and couplings. You can remove copper fittings and reuse them by following a straightforward procedure that requires a moderate amount of time and effort.

Can you reheat a solder joint?

Re: Reheating Soldered Copper Fittings? You can re heat and move it. You might brush a little flux on it first and heat slowly The problem with re heating a joint is getting it too hot and ruining the solder seal. Fix one side firmly so that as soon as it moves you can adjust it and quickly leave it alone.

How do you remove solder without desoldering tool?

How to: Solder removal without a solder sucker

  1. Step 1: Materials: …
  2. Step 2: Heat the iron, strip the wires. …
  3. Step 3: Open the flux, dip your homemade wick. …
  4. Step 4: Wick the metals away! …
  5. Step 5: Cut, twist, repeat…

What is a desoldering wick?

Desoldering braid or “wick” is a pre-fluxed copper braid that is used to remove solder, which allows components to be replaced and excess solder (e.g. bridging) to be removed.

Can you overheat copper pipe when soldering?

Overheating is a major problem when brazing or soldering copper pipe because the flux will burn (become oxidized), stop working, and become a barrier to tinning. In addition, a heavy oxide can be formed on the pipe itself, preventing a bond from forming between the filler metal and the pipe surface.

Can I solder without flux?

Yes, you can solder without flux. While it is helpful in the process of soldering as the flux helps break down the oxides on the metal, it is not needed. Also, most solder nowadays come with a rosin core which does the job of flux helping breaking down oxides.

How can you tell if a solder joint is good?

A good solder joint should have an even band of solder showing all the way around. If you see an area that looks as if it needs more solder, brush a little flux onto the joint. If the joint is still warm, the flux will melt and flow into the void. Then reheat the joint and resolder.

Why are my solder joints dull?

Dull (non-shiny) solder joints are usually the effect of coarse grain structure in the solid solder joint (though there can be other causes). The more slowly a joint cools, the coarser the grain growth and, conversely, the faster the joint cools, the finer the grain growth and the shinier the joint.

How can you tell if solder 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.

Why are copper fittings cleaned before soldering or brazing?

It cleans the metal making the solder stick to the fittings and pipe better it cleas oxides and oils. What is the purpose of flux? The longer that copper is kept at the higher brazing temperature, the greater the formation of copper oxide, and nearby valves may be overheated.

What is the purpose of purging with nitrogen while brazing?

What is Nitrogen Purging? Nitrogen purging is a task performed during brazing which helps ensure your HVAC system runs smoothly and without issue. Almost every HVAC installation requires flowing dry nitrogen through the copper pipes during brazing to prevent oxidation.

What harmful light is produced during soldering?

Welding arcs and flames emit intense visible, ultraviolet, and infrared radiation. UV radiation in a welding arc will burn unprotected skin just like UV radiation in sunlight. This hazard is true for direct exposure to UV radiation as well as radiation that is reflected from metal surfaces, walls, and ceilings.

What is the purpose of flux?

The main purpose of the flux is to prepare the metal surfaces for soldering by cleaning and removing any oxides and impurities. Oxides are formed when metal is exposed to air and may prevent the formation of good solder joints.

Can I use Vaseline instead of flux?

Yes, Vaseline works just as well as commercial flux, and you can even buy a generic brand. Petroleum jelly is primarily made from waxes and mineral oils so that it won’t corrode your components. Plus, it cleans away the gunk and eliminates metal oxides that could compromise your bond.

Why does my solder not stick?

Flux removes oxidation from metals, and it’s crucial because solder won’t stick to oxidized metals, and metals oxidize very quickly at soldering temperatures. 3. Not enough heat: A 15 Watt iron is fine for small chips, but any larger connectors or wire bigger than 16 gauge will cause problems.
