Soldering specifically involves the process of melting a filler metal that has a melting point below 840°F to bond metallic surfaces together. This technique is commonly used in electrical connections, plumbing, and various craft applications, where precision and control over the materials being joined are essential.

The temperature specification is significant because it distinguishes soldering from welding; soldering does not melt the base metals being joined but instead relies on a filler that flows into the joint at lower temperatures. This process ensures that the integrity of the base metals remains intact and minimizes the risk of warping or damaging them due to excessive heat.

In this context, the inclusion of lower temperature thresholds is what makes soldering a preferred method for delicate applications—where it is essential to bond materials without compromising the surrounding structures.
