Soldering is the process of joining metals to form an electric circuit or mechanical joint. It can provide the necessary heat for melting solder and quickly create bonds between two pieces, cool down into strong joints that are durable enough to withstand even more extreme conditions such as temperature fluctuations in water pipes. These days, you can take a quick course in soldering at your local mobile training centres.
Soldering is a process that requires heat of 400 degrees Fahrenheit. This temperature has to be much lower in comparison with the one needed for welding. This is because the solder conducts electricity. After all, it is metal. To make sure that your connections are solid and efficient, the solder will run through to form a stronger bond.
