Abstract
The invention provides a convection type brazing apparatus for metal workpieces such as aluminum, copper, iron and so forth that enables uniform heating of the metal workpieces to prevent deformation of the workpieces and can shorten a heating time to achieve a higher operation efficiency. A heating medium gas heated by a tube heater in a thermal medium gas heating chamber is forwarded by a fan to manifolds A and B located on both left and right sides, to be blown through a multitude of nozzles toward workpieces W to which a brazing material and flux have been applied in advance. Once the workpieces temperature has reached a predetermined temperature for brazing, a switching valve located in an upper duct is activated so that the heating medium gas is intermittently blown to the workpieces. As a result, a temperature slope of the workpieces is minimized and uniform brazing can be performed.
