The Formation of Cracks after Welding

Aircraft Engineering and Aerospace Technology, 1939
SOME 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 ...

Modelling the process of formation of welding aerosol in welding of mining equipment

Welding International, 2012
The 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.

Influence of Welding Current on Formation of Weld Bead in TIG Welding for Joining Thin Plates

Advanced Engineering Forum, 2018
In 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, 2013
Abstract 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 ...

The influence of a welding current modulation on weld seam formation

2016
The 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.

Influence of Ultrasonic Vibrations on the Formation of a Welding Seam

Russian Engineering Research
The methods of ultrasonic influence on the formation of welds are analyzed. The processes occurring in a weld as a result of ultrasonic vibrations are studied. Positive factors of ultrasonic influence are established that improve the quality of welded joints.
