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.
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!!!!!
Dry soldering refers to a poor soldering technique where insufficient heat is applied to the joint, leading to inadequate melting of the solder. This results in a weak connection that may not conduct electricity properly and can lead to intermittent failures. It often occurs when the soldering iron is not hot enough or when the surfaces being joined are not properly cleaned. Proper soldering requires adequate heat and clean surfaces to ensure a strong, reliable joint.
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.
cold soldering is when the soldring part is not well soldard or the soldring has being disjoint.
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.
In batteries and soldering.

Soldering irons are designed to heat up the lead in solder to its melting point, allowing it to flow and create electrical connections. The high temperature of the soldering iron transfers heat to the lead in the solder, causing it to melt and bond with the materials being soldered.

Common soldering tools include a soldering iron or soldering station for heating and applying solder, solder wire (often made of tin and lead or lead-free alternatives), and a soldering iron stand for safe storage. Other useful tools are soldering flux to improve solder flow, desoldering pumps or wick for removing solder, and tweezers for handling small components. Safety equipment, such as goggles and a fume extractor, is also important to protect against fumes and accidental injuries.
Soldering of copper is a chemical change. This is because when soldering, the material undergoes a change in its chemical composition due to the reaction between the metal and the soldering material, typically a mixture of metals such as tin and lead. This results in the formation of new compounds that bind the parts together.
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.

Soldering wire is usually made of a combination of tin and lead. The most common ratio is 60% tin and 40% lead. However, due to environmental and health concerns, lead-free solder wire made of tin, silver, and copper is also widely used now.
It is not recommended to use expired liquid flux for soldering as the effectiveness of the flux diminishes over time, which can lead to poor soldering results. It is best to use fresh flux to ensure proper soldering and avoid issues such as weak joints or oxidation. Expired flux may also contain harmful chemicals that could pose health risks during soldering.
