Abstract

In automotive industries, joining materials have been a important process. One of the joining method was brazing. It was used to joint two materials which have different properties. There were many dificulties to joint different properties of materials due to the different weld ability. In this research, the aim is to joint aluminium and carbon steel by using brazing method. The material used in this research was 2 mm thick of aluminium and 1.6 mm thick of carbon steel. Brazing will be conducte by using aluminium filler which has comercial name as alusol. ASME IX was used to manufacture the specimen and ASTM E8 was used for tensile test of original material without joining. The micro hardness test was carried out by using AWS D8.9-97 standart. ASTM E407-07 was selected standard for macro and micro photograph. Tensile test of base metal of aluminium was delivered average tensile stress of 112.53 N/mm2 and average strain of 3.58%. The maximum shear stress in the test was 41.74 N/mm2 and strain of 8.5%. Vickers microhardness test of the specimen was shown the highest hardness was on the carbon steel while the lowest hardness was on HAZ (Heat Affected Zone) of aluminium. The macro photo of alusol was shown the position of alusol, aluminium and carbon steel in different color. Micro structure of aluminium in HAZ was shown changed which the grain size has increased. While in the carbon steel, perlit grain has increase as well in HAZ. For the alusol filler, it was micro structure changed become smaller than before brazing process.
