Stud Arc Welding – Changes of the main welding parameters due to welding on unclean surface

open access: yes, 2008
The main purpose of welding parameters monitoring systems is to monitor the welding voltage and current in real time (on-line). This relies on experiences that useful information about welding process quality can be gained by analysis of welding voltage and current dynamics.
