soldering is meade by the chemical element called lead
Lead melts easily
lead burning or lap joint soldering
In batteries and soldering.

Since question is not clear two answers can be given on the assumption that the question is about dry soldering. Thoroughly clean the part to be soldered, apply flux re-solder the connection. The second answer is normally lead will not be kept on a soldering point. the technician doing soldering has to use lead and flux separately. ================================ There are still solders that contain lead. The European Union prohibited excessive amounts of lead in consumer products (WEEE and RoHS), so there are lead-free solders. But there are industries in which the lead-free solders are not acceptable.
Lead-based solder uses 250 °C to 280 °C or 300 °C while lead-free soldering needs a higher temperature, about 350 °C to 400 °C.
Lead sticks very well to copper. A lead+tin solder was used for soldering components to copper PCB traces for decades.
Soldering irons are usually used with rosin core solder. Sometimes it has lead in it but often not since its toxic. Most of the time its for heavy soldering like heavy gauge wires or older circuit boards since the tips are fairly big. They also have a decent temperature control so anything that is delicate like large SMD soldering.
Have you ever had a soldering iron roll off the table and land on your wrist, burning a hole that took over a month to heal? I did in 5th grade while building one of the Radio Shack electronics kits I had received for Christmas! Learning from that I made my own soldering stand from a small metal can and poured over a half inch of lead into the bottom from my lead soldier casting set to make sure that the weight of the soldering iron could not tilt the soldering stand!!! I was never going to run the risk of a soldering iron getting away from me again!!!!!
It's used in electronics (specifically soldering). Solder is a combination of tin and lead.
Because it melts easily and is good in a solder mixture to hold wires together.
Soldering and brazing both join two parts by melting a different metal as an adhesive without damaging the two parts being joined. Soldering uses a different metal that has a lower melting point (usually lead-based) than the metal used in brazing (usually silver). This allows easier joining in soldering, but a stronger bond in brazing.
Soldering irons come in a variety of sizes and shapes. There is a wide selection of soldering irons, soldering pencils, soldering stations and soldering guns available on market in the USA.Which soldering iron is the best soldering iron for you depends on the soldering work you are planning to do and how often you are planning on using your soldering iron. The following four factors should be taken into consideration when picking a soldering iron that will be used for soldering projects on circuit boards:1) ) type of the soldering tools2 wattage of the soldering iron3)temperature control4) tip size and shapeTypes of soldering toolsAll soldering tools can be divided in four different groups-Soldering pencils-Soldering station-Soldering rework /repair stations systems-Soldering gunsSoldering pencilsSoldering pencils are the simplest (and the cheapest) soldering tool. Soldering pencils are good only for simple do-it-yourself projects. The price range of the soldering pencils is $10-$30Soldering stationsSoldering station consists of two parts: soldering pencil and a power station. Soldering pencil is attached to a power station. Power station controls temperature of the iron tip in the wide range. It automatically keeps the iron tip at an appropriate temperature. Desired temperature of soldering iron is set with knob on the face plate of power station. Soldering station can be used for most of soldering projects. It can be used for soldering of through-hole components on circuit board as well as for soldering of very fine surface-mount components as small as 0603 and 0805. The price range of the soldering stations is $40-$150.Soldering rework /repair stations systemsSoldering rework/repair systems are complex soldering tools which are mostly used in industry or in the high-volume manufacturing facilities. This soldering systems are the most expensive soldering tools since they usually consist of power station and 4 or 5 hand pieces including soldering iron, hot-air gun, tweezers , vacuum pump which is used for the de-soldering work. The price range of the soldering systems is $250-$2500.Soldering gunsI do not recommend using soldering guns for fine soldering projects on circuit boards.The most popular brand names for soldering irons in the USA are Weller, Pace and Hakko. Aoyue soldering irons are less popular brand name in the United States then Weller or Pace. However, Aoyue soldering irons are much cheaper and they are good combination of quality and price.There is a wide selection of iron tips. Iron tips come in different shapes and sizes. For most soldering projects you can use screwdriver tip 0.062" or 0.032". For fine soldering projects and for soldering of small surface-mount components you can use conical tip 1/16".ConclusionI recommend a temperature controlled 50W soldering station. This soldering station will be excellent tool for most of soldering projects. My top recommendations are:-Weller WESD51 soldering station (digital)- Weller WES51 soldering station (analog)- Hakko FX-888 soldering station- Aoyue 2702A soldering station- Pace ST-25 soldering station
There are a number of different alloys that can be used as joiner alloys in soldering. Which one you choose would depend on which metals you want to join and whether you want your joiner alloy to be lead-free or not.
When you use a soldering iron you would be soldering some kind of metal frame or something because soldering irons are irrelevant to soldering iron. Sorry, not applicable.
Lead free solder is required when connecting copper tubing used for drinking water. For electronic soldering as well as drain pipes in a home, solder with lead works very well.

A soldering iron is a straight tool, sort of like a long screwdriver. A soldering gun actually looks like a gun or a drill.
Tin, lead, bismuth, etc. Many soldering alloys are known today; see the link bellow.

Soldering creates ozone. It is a pollutant.
