An efficient nondestructive testing method of resistance spot weld quality is essential in evaluating the all welded joints automotive components a car body production line. This study proposes prediction algorithm for welding that can predict geometrical and physical properties spot-welded joint evaluate based on acceptance criteria. To this end, four statistical models main joint, including t...

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...
