Dynamics of the gas metal arc welding process research - laboratory system and sound monitoring module-

To ascertain application possibility of the sound monitoring for dynamics of the gas metal arc welding (GMAW) process research, the following was parallel performed on the laboratory system: (a) established DC voltage / DC current monitoring and (b) developing sound monitoring. The first part of the paper briefly describes the developing laboratory system and sound monitoring module. In the second part, experimental results with the applied data processing method are presented. The third part is devoted to the necessary adaptation of the sound monitoring module.
