Lead solder is a mixture (alloy) of lead and tin (in different proportions) that has a lower melting point than either of the components. It is used to join metal components together in electronics, lead and zinc came in stained glass windows etc.
There are also silver and gols solders for jewelry.
waht is the function of soldering lead
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.
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!!!!!
No ANSWER: lead is poisonous to humans on a grand scale. like mercury It collects and add up. certainly putting solder the mouth is bad. Lead replaces calcium
The main tools for soldering include a soldering iron, a stand for the soldering iron, and solder. You'd likely use other tools such as brushes, picks, heat sinks, solder wick, desoldering irons, etc.
waht is the function of soldering lead
soldering is meade by the chemical element called lead
Lead melts easily
In batteries and soldering.
lead burning or lap joint soldering
Lead is unlikely to become airborne during hand soldering because the operation occurs at a temperature much lower than the boiling point of the lead.
solder tin, lead,
Lead "burning, Soldering with the use of lap joints

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.
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 sticks very well to copper. A lead+tin solder was used for soldering components to copper PCB traces for decades.
