Development of Stand Alone Application Tool for Processing and Quality Measurement of Weld Imperfection Image Captured by μ-Focused Digital Radiography Using MATLAB- Based Graphical User Interface

PZ Nadila, Yupiter HP Manurung, SA Halim وآخرون · المجلة العُمانية للبحوث الهندسية · 2012 · 10.24200/tjer.vol9iss2pp64-79

Digital radiography incresingly is being applied in the fabrication industry. Compared to film- based radiography, digitally radiographed images can be acquired with less time and fewer exposures. However, noises can simply occur on the digital image resulting in a low-quality result. Due to this and the system’s compl …

Simulation Study on Multipassed Welding Distortion of Combined Joint Types using Thermo-Elastic-Plastic FEM

RN Lidam, Yupiter HP Manurung, MR Redza وآخرون · المجلة العُمانية للبحوث الهندسية · 2012 · 10.24200/tjer.vol9iss2pp1-16

This paper investigates the angular distortion induced by the gas metal arc welding (GMAW) process on the combined butt and T-joint with a thickness of 9 mm. The material used in this study was low manganese carbon steel S355J2G3. A 2-D and 3-D thermo-elastic-plastic finite element (FE) analysis has been developed to s …
