Crimping vs. Soldering Electrical Wires: Which Is Better?
There are two methods for bonding electrical wires: crimping and soldering. But which is better? In this guide, we’ll explore the benefits of crimping and soldering to determine which method is superior.
What Is Crimping?
Crimping is typically used as an alternative to soldering in applications where excessive heat could cause stress on components such as cable connections. In crimping, an individual uses a special crimping tool to install a connector on a cable and then places the exposed wire at the end of the cable into the connector.
The individual then firmly squeezes the handle of the crimping tool, and the connector and cable are joined securely. Automated crimping machines can do the entire process quickly without human input.
Benefits of Crimping
Crimped connections are more durable than soldered ones because the crimp makes the connection flexible, heat-resistant, and abrasion-resistant. Crimping typically has more consistent results than soldering, as once someone learns the proper wire crimping technique, the process is relatively easy and repeatable.
Soldering varies depending on the skill of the technician and the tools at hand. In industries like automotive and aerospace, where durable and reliable connections are critical, crimping is the favored method.
What Is Soldering?
Soldering is the more traditional method of connecting wires and is similar to welding, but instead of melting the two components together, it melts a special filler metal to create a bond. Soldering uses a soldering iron to heat a melted metal alloy, solder, to above 600 degrees Fahrenheit. This method bonds the cable and terminal and then cools for a strong connection.
Benefits of Soldering
Soldering is an accessible and simple process that many people can learn. It is the default method in many industries that require strong connections but can’t weld the components, like consumer electronics with conductive materials.
Interesting Fact
Historical evidence suggests ancient Mesopotamians soldered things over 5,000 years ago. And since soldering has been around forever, it’s an easy skill for technicians to learn.
Which Is Better?
We’ve discussed the benefits of crimping and soldering electrical wires, but which method is better? While both have their advantages, crimping is typically ideal for wire and cable connections because connecting the components protects the connection from moisture, dirt, and debris.
Soldering doesn’t offer the air-tight seal that a crimped connection provides, so crimped connections are typically more durable and last longer. But if that’s not a worry for your application, it may be easier to solder instead—it mostly comes down to the individual and application.
