Mechanical parts during service may be subjected to cyclical loading and high stresses, which make fatigue life prediction extremely important. The finite element method is commonly used in research institutions and industry in order to estimate life span of mechanical parts. In this study, an experimental investigation of the geometrical dimensions and mechanical properties of a weld joint, an...

In many applications that use high strength steels, structural integrity depends greatly on weld quality. Imperfections and the bead geometry are influencing factors mechanical properties of welded joints but, especially in fatigue strength, they cause a great decrease. The proper knowledge these two is important from nominal stress approach to fracture mechanics approaches. Studies concerning ...

This paper focusses on effect of flat wire electrode gas metal arc welding (FW-GMAW) inline during the process to improve quality weld bead. Since perimeter has enlarged, turbulence molten droplet characteristics is altered due electromagnetic force. To bring out, butt joint are proven with use electrode. The experimental results indicated that, and their orientations significantly factors bead...

Plane welds are a common type of weld in industrial sites. When the welding robot multiple types plane at same time, traditional teaching and programming modes become relatively complicated. Therefore, order to solve problem automatic various welds, taking V-type butt, I-type lap as examples, this paper proposes extraction method based on 3D vision. Firstly, realize line segmentation workpiece ...

For the creation of surface reinforcement particles in metal matrix, friction stir processing is frequently utilized. Formation aluminum/SiC composite on Tungsten Inert Gas (TIG) butt weld Al5083 by a novel technique direct (DFSP) using hollow tool successfully demonstrated this present work. Deposition SiC zone DFSP was confirmed X-Ray diffraction (XRD) method. Micro analysis joint achieved me...
