Timefrequency diagram is applied to estimating the stability of gas metal arc welding process. A methodology has been developed to obtain indexes based on image processing of the spectrogram in order to evaluate the relationship between the spectrogram and the stability of process. The acoustic ...
Welding operations which use argon as the shielding gas results in an atmosphere contaminated with argon which is toxic at high partial pressure. Argon has a relatively high melting point (-189.2C) and is a solid at the temperature of liquid nitrogen. This presents a potential problem of blocki...
In Russia, natural gas, jointly produced with petroleum, was used in Baku in 1871. In the early 1920s, developments in welding technology enabled the construction of steel pipes capable of handling higher pressures. This permitted the development of larger network systems over extended areas, ...
This study examines the welded joint between P91 steel and Incoloy 800HT using the activated tungsten inert gas (A-TIG) welding process. The focus is on analyzing the microstructure and evaluating the mechanical properties of joints made with different compositions of activating flux. Owing to the...

Figure 1.Schematic diagram of a gas refrigerator: (Cm) compressor, (Co) cooler, (RH) regenerative heat exchanger, (E) expander, (N) object to be cooled work. The cycle based on throttling is the simplest but is not very efficient. Therefore, it is used only for the very small gas re...
Each two plates are welded together along the seams by automatic laser welding machine to form a plate pair. Each plate pair are then welded onto the four columns to form a plate bundle, which is the core heat transfer body of the full set of ...
