Ending1: 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. Ending2: The movements in the other components move the pieces if the components are able to be soldered together. [title] Know what solder can be used. Ending3: 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. Ending4: 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.
