Flux cored arc welding (FCAW) is applied due to its remarkable results and advantages (high productivity, joint quality etc) in various fields (industrial construction, naval, chemistry, petrochemistry etc.). FCAW disadvantages, mainly the emission of pollutants, can be counteracted by their rigorous control and local forced ventilation in the production. Control measures that can be used for m...

This research uses shielded metal arc welding (SMAW) method combined with flux core art (FCAW) using ASTM A36 10 mm steel material and double V seam. Then the electrode used in this study is for SMAW E7018 welding. , while FCAW E71T1 The current variations are 60A, 75A, 90A 190A, 205A, 220A. purpose of to determine optimal that produces highest tensile impact strength differences microstructure...

To investigate influence of welding parameters on weld bead geometry in underwater wet flux cored arc welding (FCAW), orthogonal experiments of underwater wet FCAW were conducted in the hyperbaric chamber at water depth from 0.2 m to 60 m and mathematical models were developed by multiple curvilinear regression method from the experimental data. Sensitivity analysis was then performed to predic...

Two welding methods of FCAW (Flux-cored arc welding) + FCAW, and GTAW (Gas tungsten were compared to identify effective routes for STS 316L/A516-70N clad stainless steel. Since the speed method is slower than that method, amount heat input large, size heat-affected zone formed larger, angular deformation also large. The microstructure specimens investigated by computational simulation, results ...

This investigation aims to explore determinants of exposure to particle size-specific welding fume. Area sampling of ultrafine particles (UFP) was performed at 33 worksites in parallel with the collection of respirable particles. Personal sampling of respirable and inhalable particles was carried out in the breathing zone of 241 welders. Median mass concentrations were 2.48 mg m(-3) for inhalab...

The microstructural and mechanical evaluation of 9% Ni steel with flux-cored arc welding (FCAW) was performed two different Ni-based weld metals: Inconel 625 Hastelloy 609. metals showed changes depending on the temperature gradient crystal growth rate for each region during cooling after welding. A cellular/planar exhibited at bottom metal, which rapidly cooled in contact cold base metal. Colu...
