How do you solder?

Answer 1

Step 1) Twist the two parts together (only do this if you are soldering two wires together).

Step 2) When the soldering iron is hot enough, tin the tip of it with solder or tinning compund.

Step 3) Heat the parts that are going to be joined. DO NOT MOVE THE SOLDERING IRON.

Step 4) Slowly push the solder into the heated area. Sing 1 2 3 4 5 once I caught a fish alive while you are doing this. This is becuase when you finish singing it, enough solder will have melted onto the joint.

Step 5) Clean the tip of the soldering iron by rubbing on a damp sponge.

Step 6)Leave the solder to cool and harden.
u have to use the right type of metals but for like wires u would twist the two together like _ _ not like /\ under a wire nut and use a soldering stick to heat up the exposed part of the wire and brush the solder across and it will melt on it and down into it

Use the soldering iron to heat both the solder pad and the parts lead at the same time. Give it a couple seconds to heat up and then apply your solder, using just enough to cover the soldering pad and connect to the wire lead. Then let the connection cool. Be sure that the part lead doesn't move during the cooling phase or you'll get what they call a cold solder joint. It takes a little practice but it's no rocket science, either.

The solder should be a `rosin core` solder. What that means is that the solder has soldering flux built into it which helps clean the connection after being heat activated and also helps to ensure that the solder will flow evenly as well as adhere to the metal.

A cold solder joint looks grainy and dull in appearance. A good solder joint looks shiny. If you get a cold joint, reheat it and let the solder cool down again, and if necessary, it's OK to add a touch more solder.
