Effect of process parameters on arc behavior and weld formation in weaving gas tungsten arc welding

Journal of Materials Engineering and Performance, 2022
Abstract The arc welding with weaving has been used widely to obtain better weld quality by avoiding lack of side wall fusion and improve the weld efficiency by obtaining the wide weld bead. But the effect of weaving process parameter change on the weld is not clear.

Effect of helium gas on arc characteristic in gas tungsten arc welding.

QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 1985
Effects of helium gas on the maximum arc pressure and on the critical travel speed to melt a base metal were investigated in GTA welding.Results were obtained as follows;(1) The critical speed in helium (He) gas arc is much higher than in argon (Ar) gas arc.

Mobile electromagnetic levitator for time‐resolved in situ X‐ray diffraction studies of high‐temperature phase transformations

Journal of Synchrotron Radiation, EarlyView.
A mobile electromagnetic levitator combined with time‐resolved synchrotron X‐ray diffraction enables in situ studies of high‐temperature phase transformations without container‐induced contamination and reveals the first direct observation of metastable phase formation in undercooled Fe–Co alloys.In situ observations of high‐temperature transformations,

Occupational exposure to metal welding and cataract: A systematic review and meta‐analysis

Acta Ophthalmologica, EarlyView.
Abstract Background Metal welding generates ultraviolet radiation (UVR) of cataractogenic wavelengths, and UVR emitted during welding has been associated with cataract formation, but results from prior studies are conflicting. Methods We conducted a systematic review and meta‐analysis of epidemiological studies addressing associations between ...
