In our last post, we talked about solder as it relates to the assembly of electronic components. For clarity, we wanted to examine some other techniques for joining metal components. In this post we look at welding.

According to the What Is Welding? article over at wiseGEEK.com, “Welding is the process of joining metals by melting the parts and then using a filler to form a joint.” By comparison, soldering involves the melting of the solder between two metal components to form an electrical connection rather than actually melting the components as with welding.

With welding, the components are, more or less, permanently joined with the goal of a structurally sound connection. With soldered joints, the solder can simply be melted and the two components separated before the the solder solidifies. Soldered joints are not intended to be structural. Rather, they are primarily used to provide reliable electrical conductivity.

In our next post, we’ll be looking at brazing before we move on to the whys and hows of the different metal joining techniques.
