Evaluation of the Melted Zone Microstructure in the Interface of the Dissimilar Weld between A335 Low Alloy Steel and ER309L Filler Metal by Gas Tungsten Arc Welding
In the present study, the microstructure and mechanical properties of the dissimilar welding between ASTM A335 low alloy steel and ER309L austenitic stainless steel were investigated using the gas tungsten arc welding process. The welding of dissimilar materials between ASTM A335 low alloy steel and ER309L austenitic stainless steel was found to have a significant effect on the microstructure w...
متن کاملEvaluation of metal weld-zone by using Poisson’s ratio distribution
Poisson’s ratio has not received much attention because of its narrow range of measured values and difficulties in measurement. In previous work, genuine non-destructive evaluation method of characterizing weld-zone using Poisson’s ratio distribution was proposed. The method was to use immersion ultrasonic testing for measuring longitudinal and transverse wave speeds simultaneously. In present ...
متن کاملNeurofuzzy model-based predictive control of weld fusion zone geometry
A closed-loop system is developed to control the weld fusion which is specified by the topside and back-side bead widths of the weld pool. Because in many applications only a top-side sensor is allowed which is attached to and moves with the welding torch, an image processing algorithm and neurofuzzy model have been incorporated to measure and estimate the top-side and back-side bead widths bas...

متن کاملThe Evaluation of Tropospheric Ozone Formation in the Downwind of the South Pars Industrial Zone
Hydrocarbon Processing Industries (HPIs) emit large amounts of highly reactive hydrocarbons and Nitrogen Oxides to the atmosphere. Such simultaneous emissions of ozone precursors result in rapid and high yields ozone (O3) formation downwind. The climate of the Middle East has been shown to be favorable for O3 formation in summer. There are also vast activities in processing oil and gas in this ...
