This work presents the analysis and development of the TIG-MIG hybrid welding process based on the analysis of the voltage and current signals generated during the metal transfer. The effect of the parameters on the stability of the process is evaluated using on stated stability indices. The stability indices evaluated showed little variation between them with respect to the stability classification by experimental conditions. A comparative analysis of stable and unstable conditions is

Finally, the visual inspection of the weld beads and a statistical analysis for the validation of the obtained experimental results are carried out. As a result of the research, the effectiveness of the method used for stability analysis in hybrid TIG-MIG welding processes in the manufacturing area was demonstrated.
