摘要
-Underwater friction-stir welding (UWFSW), method die solidstate joining, is used widely in both similar and dissimilar combining of Aluminium, Magnesium, Copper and their alloys. Its applications are in a different field such as aeronautics, automobiles, shipbuilding, etc. The paper compares mechanical properties such as tensile and compressive strength, micro-grain structure, Impact strength, and hardness of the materials on different aluminium alloys AA5052 and AA6082. These properties are compared under certain selected variables such as continual tool rotational speed, rate of welding using underwater friction-stir welding process. In underwater friction-stir welding, parameters of the tool impact a important role in determining joint strength of weld joint. H13 tool steel has been used as a tool material for a variety of pin profiles, including cylindrical, cylindrical threads, and tapered hexagons. The Taguchi L9 method was used for statistical analysis. This experiment helps to identify the main factors that affect the hardness, bending, impact and joint's tensile stress.
