I. Abstract: The prediction of the optimal weld bead width is an important aspect in shielded metal arc welding (SMAW) process as it is related to the strength of the weld. This paper focuses on investigation of the development of the simple and accurate model for prediction of weld bead width of butt joint of SMAW process. Artificial neural networks technique was used to train a program in C++...
About one million workers worldwide are engaged in welding processes, where they are exposed to a complex mixture of inhalable pollutants. Adverse effects in the respiratory system can occur due to this occupational exposure. Currently, legislative limits only exist for inhalable and alveolar particles. However, epidemiologic and toxicologic studies show that especially ultrafine particles (UFP...
pulsed current plasma arc welding (pcpaw) is one of the most widely used welding processes in sheet metal manufacturing industry. in any fusion arc welding process, the weld bead geometry plays an important role in determining the mechanical properties of the weld and hence quality of the weld. moreover, the geometry of weld bead involves several simultaneously multiple quality characteristics...
welding is a process in which two or more metals are attached by the use of heat and, in some cases, pressure. direct exposure and inhalation of welding fumes causes acute and chronic side effects in humans. kidney damage is one of these important side effects. β2 microglobulin is an 11.8 kilodalton protein and levels increase in the case of some inflammatory and viral diseases, or kidney malfu...
