Choices: a). When making a bond, the fusing process is similar to welding. For example, if you are turning a brass or gold plating piece, you would melt a steel plate.. b). The movements in the other components move the pieces if the components are able to be soldered together. Know what solder can be used.. c). In welding, the component pieces are melted together; in soldering, a softer metal with a lower melting point is used to connect them. Because soldering doesn't melt components, it's useful for more delicate applications, such as electronics work, or plumbing.. d). This is different from welding metals while welding metal together. Soldering is a form of welding that shows that there are gears on components and mechanisms that are interchangeable..
c).
