In the application of welding "GTAW" has several advantages such as&#x0D;welding results do not need to be cleaned from slag or corrosion residue. Due to&#x0D;the above-mentioned advantages, the precise determination of weld parameters&#x0D;and offset by the welding skills of welded characteristics will be affected. The&#x0D;purpose of this research is to know the characteristic of GTAW welding on low&#x0D;carbon steel, by observing the shape of weld bead and supported by the result of&#x0D;macro photo of welding result from various variations of currents and variations&#x0D;of the angle geometry of tungsten electrode.&#x0D;The method used in this study is an experimental method, with treatment of&#x0D;parameters of parameters of current and parameters of angle geometry variation of&#x0D;tapering of tunsten electrode. Analyze method is done to welding result and macro&#x0D;photo of T connection weld result.&#x0D;From the analysis of GTAW weld metal form with type T connection&#x0D;through variation of electrode geometry angle and strong welding current in this&#x0D;research, can be drawn some conclusions, among others, from some variation of&#x0D;weld geometry angle which gives good shape of welding characteristic and deep&#x0D;penetration is angle 300 of ampere 90 A.
