An automatic brazing system that can maximize adhesion of the joining object by reducing a temperature deviation of the joining object consisting of at least two base metals with different thicknesses and thereby brazing the joining object at a state that wetting of a filler metal is good is provided. An automatic brazing system comprises: a feeding unit(100) for feeding a joining object(M) to the entrance side atmosphere unit; an entrance side atmosphere unit(200) having a first entrance door member and a first exit door member installed at both sides thereof; a heating unit(300) having a second entrance door member and a second exit door member installed at both sides thereof to heat the joining object fed from the feeding unit to a predetermined temperature for a set time; a cooling unit(400) closely connected to the heating unit to cool the joining object transferred from the heating unit in a reductive atmosphere; an exit side atmosphere unit(500) which is installed between the cooling unit and the transfer unit and has a third entrance door member and a third exit door member installed at both sides thereof; a transfer unit(600) for transferring the joining object discharged from the cooling unit to the atmosphere; and an atmosphere control unit which is connected to the exit side of the entrance side atmosphere unit, and has an atmosphere control unit including sensors for sensing concentrations of oxygen and nitrogen and an injection pipe for injecting nitrogen according to the sensed concentrations.
