understanding Soldering : vacuum or gas soldering

Like many sheet metal terms, soldering and welding are used interchangeably. However, while these two operations are similar, their process and sub-techniques are different. The main difference between welding and soldering is melting. In soldering, metal fabricators heat the metal to be bonded but never melt them. In welding, metal fabricators melt the base metal. Common features of vacuum and gas soldering are as follows: All solders are made of metal materials with a lower melting point than the base metal. Liquid solder is used to wet the base metal, fill the gap between the joints, and diffuse with the base metal to join the solders. Differences between vacuum and gas soldering: The principle of vacuum and gas soldering is basically the same, but there are large differences...
