    • The invention refers to the flame soldering/brazing procedure - ECO BRAZ - of metallic and nonmetallic materials, used in industrial operations without releasing of noxious gases emissions. The soldering/brazing procedure according to the invention is achieved totally eliminating the noxious gases emissions, reducing the energy consumption for the soldering/brazing operation and improving the quality of the joints by eliminating the influence of the temperature on the joint materials, in the following stages: cleaning and scaling of the joining surfaces with soldering/brazing flux, adapted as type and method to the specification of the materials that make up the joint; preparation and positioning of the joining components according to the joining drawing and ensuring a correct joint gap in relation to the added metal; uniform heating or the joint until the soldering/brazing alloy melted with the help of a burner with HHO oxy-hydrogen gas at a pressure of 0,1-0,3 MPa; cooling of the joint with air and its protection so that it is not moved or stricken during the cooling and solidification of the soldering/brazing alloy.
    • 本发明涉及用于工业操作而不释放有害气体排放物的金属和非金属材料的火焰焊接/钎焊工艺(ECO BRAZ)。 根据本发明的焊接/钎焊方法完全消除了有害气体排放,降低了焊接/钎焊操作的能量消耗,并通过消除温度对接头材料的影响来提高接头的质量,如下 阶段:使用焊接/钎焊焊剂清洗和结垢接合表面,适用于构成接头的材料规格的类型和方法; 根据连接图准备和定位接合部件,并确保与添加的金属相关的正确接合间隙; 均匀加热或接头,直到焊接/钎焊合金在具有0〜0.3MPa的压力的HHO氧 - 氢气的燃烧器的帮助下熔化; 用空气冷却接头及其保护,使其在焊接/钎焊合金的冷却和凝固过程中不会移动或撞击。
