Abstract

Welding on aluminum alloys AA1100 using tungsten inert gas (TIG) had drawbacks and difficulties, such as porosity. Optimal control is needed to minimize the shortcoming. Welding automation is often used to ease the controls required, and one of the welding automation methods is welding speed control. It is necessary to do manual welding to determine the response of the step increase in welding speeds. This research aims to find the response of TIG welding speed control on temperature and top bead width of aluminum alloys AA1100 thin plate. Both autogenous welding and the welding using filler methods were used to find the difference between the two methods. The varied parameter in this study is the variation of step increase of welding speed. Top bead width and temperature were measured to find the step increase welding speeds response. The study results show that the higher the welding speed, the resulting top bead width will decrease. There is almost no delay in the visible change in the top bead width after applying the step increase in welding speed. Furthermore, the initial welding speed greatly affects the temperature in the next step. Also, the slower the welding speed, the hotter the resulting temperature, but it takes time for the heat to accumulate. Finally, in welding using the filler method, the temperature and top bead width are generally lower than in the autogenous method. In welding using the filler method, if the welding speed is too low, there may be an accumulation of filler itself which causes an increase in bead width.
