Solder is not the name of a particular metal. Solder is any soft metal used to join two harder metals together via melting and fusing to the parts of the joint. Many different alloys and pure, elemental metals are used for soldering. Many of the alloys combine some other metal with lead, as lead is


For Dummies explains that the key to soldering is to apply heat to the points requiring connection and not to the soldering iron itself. By doing so, the joint is evenly connected on all sides, providing a smooth transfer point for the electric current between parts.


The National Retail Hardware Association and the Circuit Technology Center provide free online tutorials covering basic soldering techniques. You can purchase a Learn to Solder kit from companies such as Electronic Goldmine and solder various components at home. A solder iron and supply of tin lead


Solder can be made up of metals such as lead, tin, cadmium, bismuth or silver. The type of solder used depends on the task at hand.


Solder electrical connections by protecting the work surface, preparing the soldering iron, mechanically connecting the materials and soldering the joint. Avoid touching the end of the soldering iron, as it is very hot.


To use a soldering iron safely, wear eye protection, such as safety goggles or glasses, at all times. Solders emit strong fumes that can be toxic, so work in a well-ventilated area to prevent buildup. Never hold the wires to be soldered with your bare hands, and do not touch the blistering hot solde


Traditional soldering material is primarily composed of lead and tin, while modern lead-free solder is made out of a combination of several metallic elements, including silver, copper, bismuth, zinc, indium and antimony. The proportion of these metals in a soldering alloy determines the properties o


Liquid solder is a brand name adhesive that is not meant for electrical soldering. Electrical soldering is commonly done with 1/32 inch rosen-core wire solder, paired with flux depending on the circumstance.


Conductive liquid solder is a conductive adhesive or potting compound that can be used in tasks in which hot soldering does not work or is not practical and may damage the material. Liquid solder can be used to seal or bond electrical components as effectively as conventional solder.


The melting point of lead-free solder depends on the alloys that have been used to make the solder. The most popular lead-free solder is the tin-silver-copper solder, which melts at 423 degrees Fahrenheit. Tin-copper solder melts at 441 F, and tin-silver solder melts at 430 F.
