Experimental simulation of surface pitting of degraded electrodes in resistance spot welding of aluminium alloys
A novel experimental technique, using specially designed electrodes (with machined annular and circular pits, and central cavities), was developed to simulate the effects of pitting morphology of the electrode tip face on weld nugget size and joint strength in resistance spot welding of aluminium alloys. Results of the experimental simulations indicate that the distribution of electrode contact...
متن کاملStudy of Mechanical Properties Change During Friction Stir Spot Welding of Aluminium Alloys
The Friction Stir Welding process is now 20 years old and the interest in it and its potential continues to increase dramatically. FSW can be applied to a multitude of products with varying material types and thicknesses. However, a continuous weld is not always required to meet the product performance requirements. Thus, one can consider some form of intermittent weld, such as Friction Stir Sp...
متن کاملLaser welding of dissimilar aluminium alloys with filler material
Laser welding of dissimilar aluminium alloys with filler material Luís Filipe Amaro Pinto Instituto Superior Técnico – Technical University of Lisbon – Portugal September 2008 Abstract The aluminium alloys are materials with great potential because of its high strength and low weight. However, the welding of dissimilar aluminium alloys is difficult in autogeneous welding, due to these alloys ar...
متن کاملProblems in Welding of High Strength Aluminium Alloys
The 7XXX series alloys are heat-treatable Al-Zn-Mg or Al-Zn-Mg-Cu alloys. They develop their strength by solution heat treatment followed by ageing. In contrast to the 5XXX series alloys, the 7XXX series alloys do not respond favourably to cold work, because they are strengthened almost exclusively by GP zone formation and precipitates which nucleate from the GP zones. Introducing many new disl...
متن کاملExperimental Effects Investigation of Ultrasonic Spot Welding on Dissimilar Al3105 and Al1050 Alloys Joining
The aluminum alloys of Al1050 with thickness of one millimeter and Al3105 with thickness of half millimeter were joined via ultrasonic spot welding (USW). To create a suitable welding, a vibrating horn (welding tool) fit to transducer and ultrasonic generator was designed using ANSYS software. Due to mechanical and thermal cycles during USW, both diffusion and mechanical mixing facilitated the...
