AB  - This paper is presenting a method for temperature transfer function (TTF)
estimation by filtering an experimentally collected data. The experimental data were
obtained in simultaneous measurements of inside and outside temperatures variations
during the period of 3 months of a building located in Belgrade, Serbia. The TTF
estimation is based on Wiener filtering technique for the dynamic systems with finite
impulse response (FIR). TTF is derivate in time and complex domain and the correctness
of the acquired transfer function is tested on the new input data set. The estimated TTF in
complex domain is used to get decrement factor (DF) and time lag (TL) between the
temperatures.

AB  - The effect of MIG/MAG shielding gas on the toughness of aluminium alloy AlMg4.5Mn weld metal has been analysed using the instrumented Charpy pendulum for standard toughness testing. The MIG/MAG welding was performed in the shielded atmosphere of Ar, as well as the mixtures of gases Ar + 0.0307 % O 2, Ar + 30 % He + 0.0317 %O 2 and Ar + 48 % He + 0.0290 % O 2. Metallographic tests have been performed in order to check the appearance and porosity of the weld metal, as well as its toughness testing at different temperatures (20, - 90, - 196 °C), using the instrumental Charpy pendulum, in order to separate the crack initiation and crack growth energy. In this way, a comprehensive insight of the effect of shielding gas on the weld metal toughness has been obtained.

AB  - An analysis of the influence of heterogeneity of the ferriteaustenite welded joint on its integrity has been performed. The Charpy specimens, with notch positioned in different regions of welded joint, have been tested using the instrumented pendulum to separate crack initiation and growth energy. In all cases tested (different heat input, room and low temperature, down to -60°C), weld metal had the lowest toughness, due to the presence of S ferrite, which was not the case in the heat affected zones, having surprisingly high toughness, including both crack initiation and growth energies. Finally, J-R curves have been obtained by using standard fracture mechanics testing procedure and compared with crack driving forces, obtained numerically using King's method, enabling estimation of influence of cracks on integrity of ferriteaustenite welded joints in cylindrical pressure vessel.
