A semi-automatic brazing furnace combination device for science and education is used for solving the problem that base materials and welding materials are vibrated and consequently dislocated before welding and in the brazing process. A movable box-type resistance furnace and a combined support containing the base materials and the welding materials are manufactured, and on the basis that immovability of a combined long-arm material containing platform bracket containing the base materials is guaranteed, a brazing furnace is moved so as to achieve the purposes of heating and cooling.
