عنوان مقاله [English]
In this research, Welding of D2 Cold Work Tool Alloy steel have been evaluated. A-TIG technique has been utilized to fine an appropriate solution in order to increase the depth of penetration and welding width compared to TIG. Active oxide flux and current intensity have considered as a main variables and their effects on penetration depth, welds width and welding surface appearance were investigated. The fluxes used in this study were ZrO2 and SiO2 and welding process was carried out at 85, 100, 115, 130 and 145A current intensities.
The results showed that arc deviation and spattering due to electrical resistance of ZrO2 flux creates improper appearance on weld surface. Welding by SiO2 flux make welds with good surface appearance and increase the depth of penetration and also decrease weld width. SiO2 flux shows the best performance by increasing of penetration depth up to 5.4 mm at 145A current intensity.
