Mesh Belt Conveyor Furnaces have two types such as copper brazing and silver brazing. The joints can be made in steel by copper brazing, when the joint is properly designed. This is generally much less expensive than silver brazing, soldering, arc welding, seam welding or spot welding. It does not require brazing flux because the furnace atmosphere cleans the work. The silver brazing produces strong, leak-tight joints with almost any metal or combination of metals. It can built an assembly in a series of brazes, using a lower temperature brazing material for each braze. It uses the annealing process as a cleaning operation.
