Effects of Operational Parameters on the Characteristics of Ripples in Double-Pulsed GMAW Process
This study focuses on the characteristics of the ripples of the weld bead formed during the double-pulsed gas metal arc welding (DP-GMAW) process. As a special output of the process, ripples include many useful information and can reflect the quality of the welding process. The work analyzed the ope...
