The hydrogen gas protection brazing furnace is mainly used for the hydrogen gas protection welding of super long work pieces. Mainly study the temperature uniformity of work area in order to improve the welding quality of work pieces. Thermal field distribution of work area is studied by the way of finite element analysis. Reduce the temperature difference between the vertical equipment and ensure the temperature uniformity of the work area by the optimized design of the structure of the equipment.
