Weld joints metallography characterization in aluminum alloys AA5754 Cold Metal Transfer welding process

Resumen [ES]

In this work, the metallographic characterization in square groove weld of aluminum alloys sheets AA5754 Cold Metal Transfer welding process was developed. The parameters current and tension were remained constant. The pulse correction and welding speed were varied in order to study their influence in various bead dimension. The weld geometry from macrographs study was obtained. Pulse correction have a significantly influence on bead width and penetration depth while welding speed have great influence on dimension of heat affect zone. The predominantly microstructure in fused zone is interdendritic network of aluminum-silicon eutectic. The paper seek to understand the relationship between welding parameters and weld pool dimensions and structural metallographic. Based on the results, was possible the optimization of welding process.
