Abstrakt (anglicky)
   Monel is a trademark for a series of nickel alloys,mainly composed of nickel (up to 67%) and copper, with some iron and other trace elements. Welding of nickel alloys is increasingly used in the industry to manufacture many important components of the jet engine, marine industries, chemical processing, etc. In this study, a 3D thermo-mechanical finite element (FE) analysis is employed to evaluate residual stresses caused by the tungsten inert gas (TIG) welding of Monel 400 (Nickel-Copper alloy) plates. Residual stresses obtained from the FE analysis are then employed as verification of ultrasonic stress measurement results. The ultrasonic stress measurement is based on acoustoelasticity law, which resents the relation between the acoustic waves and the stress of material. The ultrasonic stress measurement is carried out by using longitudinal critically refracted (LCR) waves, which are longitudinal ultrasonic waves propagated parallel to the surface inside the tested material.
