Working principle of mesh belt brazing furnace | The workpiece is driven by a stainless steel mesh belt，The work piece is placed on the mesh belt，Enter from the inlet of the preheating section,It's transmitted over the webbing，After preheating, heating (solder melting), cooling。The workpiece of discharge in the cooling section will always be protected by pure hydrogen gas，由Due to the reducibility of hydrogen, the surface of the product is bright and non-oxidized。Workpiece welding is to melt the filling material (filler metal) by heating the workpiece, and use the capillary action to fill the gap between the liquid filler metal and the base metal. After cooling, the welding purpose is achieved。 | ||||||
