Abstract The non-destructive full-field non-contact thermographic technique is applied for flaw detection of the welded joints, in real-time and offline configuration. In this paper, a procedure manual arc welding process presented. Surface temperature acquisitions by means an IR camera were performed during 8 specimen both calibration validation numerical model. investigated variables are (manual stick (SMAW) gas (GMAW) welding) joint shape (butt T joint) steel sound conditions with...

The thermal and electrical responses of additive manufactured specimens were analysed for a steel magnetic shield as case study. analysis was based on the evidence that variations in properties material can be measured phase delay diffusion through bulk. signal post-processing performed, results presented diagram. showed after heat treatment, slope diagram changed to less steep, indicating an increase diffusivity hence conductivity. conductivity predicted using Weidemann-Franz law validated...

This study presents a comprehensive understanding of the fatigue behavior 316L stainless steel specimens produced using laser powder bed fusion (PBF-LB/M) method. The investigation has been conducted through multifaceted approach that includes surface roughness analysis, density measurements, microstructural examination, testing, strain and thermographic analysis. Thermographic data processing models, i.e. bi-power law (TCM-modified) model TCM method, are applied to test results standard...

Abstract Resistance spot welding (RSW) is considered a preferred technique for joining metal parts in various industries, mainly its efficiency and cost-effectiveness. The mechanical properties of welds are pivotal ensuring structural integrity overall assembly performance. In this work, the quality attributes resistance welding, such as both nugget corona bond sizes, assessed by analyzing thermal behavior joint using physical information neural network (PINN). Starting from signal phase...

Abstract In the present paper, results of a research focused on microstructure investigation steel welded joints by means non destructive thermographic technique are presented. particular, two rough obtained irregular manual welding analyzed. Active lock in thermography phase analysis is applied, basing evidence that thermal diffusivity related to diffusion length, using contrast trend as function distance from laser spot. Diffusivity expected be dependent local and vary through different...

Abstract This study presents the preliminary outcomes of a methodology for physical and mechanical characterization various chestnut elements in different states preservation. Strategizing conservation retrofit interventions timber is necessary, to do this, it necessary establish an estimation (transmissivity, thermal conductivity, humidity level, etc.) properties (density, compressive or bending strength, etc.). essential information typically associated with defects, but there are lack...

Mechanical joining techniques are fundamental in the industrial landscape, with welded joints standing out as a primary method across diverse manufacturing sectors. In this work, we present novel contribution to fatigue life assessment of welds through 3D-Scanning weld seam. The methodology is applied on specimens tested alternate bending fatigue, showing that for real case applications, statistical approach surface irregularities joint plays keyrole. particular by means scanning, some...
