In the welding experiment of T-fillet weld of 5mm thick aluminum plates, the penetrations, deformations and leg lengths were plotted with I/√v or √I/v as parameters in abscissas. In order to obtain the most reasonable welding schedule we must consider it under the defining factors and limits shown in Fig. 9. In our case, using 1/16″∅ electrode wire, the comparatively high current range (I=240-280A, v=70-110 cm/min, I/√v=0.20-0.22×103 A/(cm/sec)1/2, I=4.5-5.5mm) is considered preferable.
