Adelaide scientists have developed a new high-speed welding technology that is set to cut production time and save industry millions of dollars. The keyhole welding process cuts hours from traditional ...

Abstract: This paper investigates the thermal characteristics of region surrounding laser welding keyhole. The thermal characteristics of region surrounding laser keyhole play an important role on the ...

Abstract: This present paper addresses the process monitoring of laser-MAG hybrid welding by using a double high-speed camera sensing system. Different welding parameter experiments are conducted ...

Mathematical statistics were used to study the stability of weld pool and the elimination of weld defects in aluminum alloy plasma arc keyhole welding at continuously varying positions. In the ...

Keyhole formation is a prerequisite for deep penetration laser welding. Understanding of the keyhole dynamics is essential to improve the stability of the keyhole. Direct observation of the keyhole ...

ABSTRACT: This paper presents an experimentally validated weld joint shape and dimensions predictive 3D modeling for low carbon galvanized steel in butt-joint configurations. The proposed modelling ...
