Laser-Gas Metal Arc (GMA) hybrid welding is fast making the transition from laboratory to production, in industries as diverse as shipbuilding to automobile manufacturing. However, many aspects of hybrid laser welding are not well understood. This work presents a summary of recent experimental explorations into various practical aspects of hybrid welding, such as joint design, gap tolerance, welding through conventional tack welds, and others. An assortment of analyses are run, including metallurgical analysis and radiographic testing, weld formation analysis via macroscopy, mechanical properties evaluations using tensile and bend testing, and process analysis using high speed imaging.
