Weld pool development and stirring behavior of AlCu4SiMg aluminum alloy during GTA welding hybrid a longitudinal electromagnetic field

摘要

Based on the numerical calculation of a hybrid electromagnetic field in the molten metal flowing unified model, we conclude that LMF affects the flowing state of molten metal at the welding pool. The welding current fluxes, direction of hybrid electromagnetic and local temperature of molten metal determine the stirring behaviors of the LMF attachment during the GTAW process.
