alloy is type B cracking model in which the strain rate has little effect on the deformation ability of the liquid film. Key word: aluminum alloy; weld metal; susceptibility; weldability... and their later performance in practice. Consequently, the following factors have to be considered when evaluating weldabilites of weld metal and base metal. They are welding operability, arc stability......
J. Cent. South Univ. (2017) 24: 2556-2564 DOI: https://doi.org/10.1007/s11771-017-3669-4 Theoretical and experimental investigation of gas metal arc weld pool in commercially pure aluminum: Effect... of the arc causes the wire at the electrode tip to melt off as droplets. The metal droplets transfer from the filler wire to the weld pool through the arc. The molten metal collects in the weld pool......
