![]() ![]() The highest strength and quality of welds was obtained when the Al99.5 filler metal was used in a braze welding process. Braze welded joints underwent tensile tests, metallographic examinations using a light microscope as well as structural examinations involving the use of a scanning electron microscope and an X-ray energy dispersive spectrometer (EDS. The tests involved the use of an aluminium filler metal (Al99.5 and two filler metals based on Al-Si alloys (AlSi5 and AlSi12. Another attractive feature of the process is that the brazed joints is hermetically sealed by the braze material.īraze Welding TIG of Titanium and Aluminium Alloy Type Al – Mgĭirectory of Open Access Journals (Sweden)įull Text Available The article presents the course and the results of technological tests related to TIG-based arc braze welding of titanium and AW-5754 (AlMg3 aluminium alloy. Test results obtained on single overlap and hat-stiffened structural specimens show that weld brazed joints are superior in tensile shear, stress rupture, fatigue, and buckling than joint fabricated by spotwelding or brazing. The process has been used successfully to fabricate Ti-6Al-4V titanium alloy joints using 3003 aluminum braze alloy. Fabrication is then completed by capillary flow of the braze alloy into the joint. Resistance spot welding is used to position and align the parts as well as to establish a suitable faying surface gap for brazing. E., Jr.Ī joining process designated weld brazing which combines resistance spot welding and brazing has been developed. [combination resistance spot welding and brazing of titanium alloysīales, T. The brazing alloy contains, by weight, 40 to 50 per cent zirconium, 40 to 50 per cent titanium, and the balance beryllium in amounts ranging from 1 to 20 per cent, said alloy having a melting point in the range 950 to 1400 deg C. Williams, L.C.Ī new and improved ternary alloy is described which is of particular utility in braze-bonding parts made of a refractory metal selected from Group IV, V, and VI of the periodic table and alloys containing said metal as a predominating alloying ingredient.
