Abstract    In this experimental work, Manganese oxide (MnO2), Zinc oxide (ZnO), Iron oxide (Fe2O3) and Magnesium chloride (MgCl2) were used as activating flux to investigate the effects for SS 304 in tungsten inert gas (TIG) welding. Ultimate tensile strength, percentage elongation, Penetration depth and width were studied of material SS 304. The experimental results indicated that the MnO2 and Fe2O3 fluxes increases the weld penetration depth and decrease the weld width but ZnO and MgCl2 fluxes shows a little effect on penetration depth and weld depth to width ratio compared with conventional TIG process. Since the activated TIG welding can increase the ultimate tensile strength and percentage elongation.

چکیده    این پژوهش مطالعه ای در مورد اکسید منگنز ، اکسید روی، اکسید آهن و کلرید منیزیم که به عنوان شارهای فعال استفاده می شوند را ارائه می دهد تا اثرات آنها را بر اس اس 304 در جوشکاری گاز بی اثر تنگستن (TIG) بیابد. مقاومت نهایی کششی، درصد ازدیاد طول، عمق نفوذ، نسبت عرض و عمق به عرض اس اس 304 مورد مطالعه قرار گرفته است. آزمایش نشان می دهد که استفاده از اکسید منگنز و اکسید آهن به عنوان شار، عمق نفوذ جوش را افزایش و عرض جوش را کاهش می دهد. همچنین، استفاده از اکسید روی و کلرید منیزیم به عنوان شار افزایش کمی در عمق نفوذ و نسبت عرض به عمق جوش در مقایسه با فرایند رایج TIG نشان می دهد. استحکام کششی نهایی و درصد ازدیاد طول در جوشکاری شار فعال TIG افزایش یافته است.
