Understanding the joining process in real time during welding can help improve quality, reliability, and manufacturing efficiency. For this purpose, a laser ultrasonic method that detect situ quality without contact would be useful. However, behaviors of propagation as well melting with increasing temperature remain unclear. Therefore, study aimed to experimentally investigate in-process behavi...

The present study presents a numerical prediction of residual stresses (RS) using the single-pass tungsten inert gas (TIG) welding process for stainless steel plates and two-pass TIG pipes. effect heat exchange between material environment was studied. work consists two parts: first one is based on determination existence numerically Cast3M software, which has been validated by literature resul...

Quality strongly depends on good mechanical properties of any manufacturing material. Similarly, quality Tungsten Inert Gas (TIG) welding Duplex Stainless Steel (DSS) like percentage elongation, ultimate tensile strength etc. Better Percentage Elongation (PE) is produced using proper parameters and their values at the time TIG welding. In this study, has been done ASTM/UNS 2205 duplex stainless...

Primljeno (Recieved): 2011-07-13 Prihvaćeno (Accepted): 2011-11-15 Original scientific paper This paper presents welding current influence on spreading of electromagnetic field in TIG welding process. The quality of welding is analyzed by „Fast Fourier Transformation“ (FFT) on recorded current. Electric and magnetic field are measured using an instrument „Macshek ESM – 100 3D Fieldmeter“ [1]. W...
