In the present study, friction spot welding or refill friction stir spot welding was performed to consolidate dissimilar AA5754 Al and AZ31 Mg alloys. The intermetallic compounds of Al12Mg17 and Al3Mg2 were primarily found in the weld, distributed at the interface between the base materials and in the Al top sheet. The distribution of the intermetallic compounds and the interfacial area between...

Welding is often used in industry as a joining technique, one of which Micro Resistance Spot (MRSW). MRSW was carried out to know the maximum load and shear stress produced on separate worksheets using AISI 304 aluminum alloys then connected lap joint. This study uses weld current, time, emphasis electrodes. In this, welding done constantly does not use cooling. The currents are 140, 280, 420 A...

INTRODUCTION The first aim of this "ex vivo split mouth" study was to compare the thermal elevation during the welding process of titanium bars to titanium implants inserted in pig jaws by a thermal camera and two thermocouples. The second aim was to compare the strength of the joints by a traction test with a dynamometer. MATERIALS AND METHODS Six pigs' jaws were used and three implants were...

The aim of this study is to evaluate the microstructures, tensile lap shear strength, and fatigue resistance of 6022-T43 aluminum alloy joints welded via a solid-state welding technique-ultrasonic spot welding (USW)-at different energy levels. An ultra-fine necklace-like equiaxed grain structure is observed along the weld line due to the occurrence of dynamic crystallization, with smaller grain...
