Webdocumented. The brazing operation, however, can give rise to both gaseous and particulate emissions from the molten alloys, flux and flames, and it is these aspects which are the subjects of this article. Hand held torch brazing can present more problems from exposure of the operator to fume than any of the automated or furnace processes. WebIf brazing doesn’t fuse the base metals, how does it join them? It works by creating a metallurgical bond between the filler metal and the surfaces of the two metals being joined. The principle by which the filler metal is drawn …
