Abstract:
This study examines two types of material, aluminium (AA-5083) and low
carbon steel (A-36). In material joining method, there are two types of welding
that can be used for combining two or more materials, fusion welding and
diffusion welding. The parameters set up for this experiment are temperature,
pressure and holding time. All of these variables were analysed from this
research. Thus, this study aims on the effect of temperature on impact testing
in diffusion welding of marine grade aluminium (AA-5083) and low carbon steel
(A-36). Literature review was used as a guidance to identify the suitable
parameters, the dimension of specimen used and the other technical data
related to diffusion welding before proceeding with the joining process. Five
different setting of temperature ware used in this joining process 520°C,
540°C, 560°C, 580°C and 600°C using fixed bonding pressure at 7 MPa and
holding time at 60 minutes, under atmospheric pressure condition. The
temperature of a furnace was 20°C it was then heated until it reached the
temperature sets for each of the experiment. The temperature was soaked for
60 minutes, then the specimens was cooled down in a furnace until the
temperature decreased to 20°C. The joining were successful and the result
from impact test (Izod) showed that the reading of impact loads from 0.6 until
1.2 Joule. For future study, there are few aspects required to improve the
result.
