Droplet measurement in laser enhanced GMAW
Proceedings of 2011 International Conference on Modelling, Identification and Control, 2011In the laser enhanced gas metal arc welding (GMAW) process developed recently, droplets of melted metal can be detached from the wire under relatively low currents with the assistance of an auxiliary force provided by a laser. The stability and the arc and the quality of the resultant welds are improved.

Thick plates of 5083 aluminum alloy are welded with GMAW and GMAW-TW processes; the influence of weld pool convection on porosity formation, microstructure, and mechanical property of the welding joints is investigated. The results showed that due to the appearance of outward flow and “push-pull” patterns, and intense mixing and stirring effects in ...

Advanced Robotic GMAW Cladding Process Development
SNAME Maritime Convention, 2013Weld cladding of carbon steel with stainless steel alloys is common for applications where corrosion resistance is required. While automated gas metal arc welding (GMAW) has been shown to reliably produce clad layers with adequate flatness, joint fusion, and acceptable levels of dilution, porosity defects have been reported as a significant issue.
