Modelling the process of formation of welding aerosol in welding of mining equipment
Welding International, 2012The thermodynamic model of the formation of welding aerosol is proposed. The thermodynamic parameters of chemical compounds and aerosol phases are calculated. A program is proposed for the numerical calculation of the level of generation of various elements with the variation of the parameters which control the welding conditions.

The Formation of Cracks after Welding
Aircraft Engineering and Aerospace Technology, 1939SOME kinds of chrome‐molybdenum steels widely employed in the construction of aeroplanes, the chrome‐manganese‐silicon steels introduced comparatively recently and even some carbon steels with a higher content than 0·2 per cent. carbon show minute cracks after welding with oxy‐acctylene, even when the actual operation of welding is carried out ...

Influence of Welding Current on Formation of Weld Bead in TIG Welding for Joining Thin Plates
Advanced Engineering Forum, 2018In this paper, a new (novel) welding technology has been applied to join 0.1 mm thin plates. An initial study on the influence of welding current on the welding properties for stainless steel SUS304 plates is discussed in this paper. The weld bead appearance on both top surface and bottom surface was observed by microscope to indicate the change of ...

Characterization of welding arc and weld pool formation in vacuum gas hollow tungsten arc welding
Journal of Materials Processing Technology, 2013Abstract An experimental method is suggested to obtain the effective arc radii for various welding conditions in vacuum gas hollow tungsten arc welding. The irradiance distribution of welding arc next above the anode workpiece is obtained by applying Abel inversion algorithm to the CCD arc image, and then used to determine the distribution of arc ...

Influence of beam space shape on weld formation in laser keyhole welding
SPIE Proceedings, 1998In laser welding of metals with a high power continuous CO 2 laser, a so-called keyhole is formed in the material. The keyhole greatly affects the absorption of laser and makes remarkable influence on the weld formation. Based on the energy balance in the keyhole, this paper presents an analytical mathematical model about the quantitative relationship

The influence of a welding current modulation on weld seam formation
2016The influence of a welding current on formation of weld is considered in the article. The advantages of welding by the modulated current are found out in comparison with welding by a direct current. It is determined that the high-frequency pulses of a current increase pressure of an arch, its stability and penetration.
