Abstract:

In the welding process of metals, two materials are joined by a filler material with low melting point (below 450 °C), also below the melting point of materials to be joined. The braze-welding filler material has a melting point over 450 °C to 1000 °C. Filler material is distributed between two surfaces of the joint by capillary action close, the blended material is applied on an electrode specially manufactured and intended operation. This paper proposes an analyze of the techniques, feathers, technology requirements, process gaseous, materials (standard data base) and conditions used in braze-welding processes. The secret of solder bonding and weld seems to be the opening that supposes to be small. Two methods are proposed and analyzed for welding process based on braze welding. Scanning electrons microscope and EDAX detector were used to characterize the weld line by micro-structural and chemical point of view. The microstructure analysis concentrated on the weld line area presents reduced dimensional variation and a modification of the materials surface smoothness. Chemical elements distribution exhibits an increase of carbon percentage on the weld line and a decrease of iron in the same time and area.
