Abstract

Grain refinement is the best way to improve the mechanical properties of fusion welds of the aluminium. The grain refinement was thereby found to be strongly dependent upon the aluminium chemical composition, where the pure aluminium has the highest grain refining efficiency. In order to increase the strength of the weld area is carried out by TIG welding with vibration on the torch which aims to obtain a smoother welded grain deposit so that its strength will increase. Theoretically, smoothing of the weld grain deposits occurs due to the welding along with with the torch vibrations arising from the peak pressure generation, the development of shear stress, the density power and the presence of laminar flow around the dendritic arm resulting in the intersection of the dendritic arms which smooths the grains. To observe the effect of the frequency and amplitude of the torch vibration in welding to refine the welded grain deposits, the research conducted with 5 Hz and 10 Hz torch vibration and torque vibration amplitude (0.25; 0.50; 0.75; 1.10; 1.60 and 2.00) mm and welding speed of 100 mm/minute and 200 mm/minute, respectively. As a comparison of the extent to which the effect or effectiveness of vibration on the torch on the weld deposit grain size produced, welding without vibration with welding speed of 100 mm/minute. Increase the welding speed will reduce grain size; on the other hand, increase the frequency have affected different grain size. Meanwhile, increase the amplitude to 0.75 mm will reduce the grain size then the grain size will unstable with increasing amplitude.
