摘要: Abstract Hybrid welding technology can be defined as the combination of a laser heat source with secondary source. In this paper new generation high power fiber was used and it coupled TIG arc Two separate sets experimental trials were performed. It included testing process parameters such power, speed current. Microstructure, microhardness weld appearance analyzed. A comparison performed between leading configuration. The results showed that configuration produces better penetration sounder weld. overall investigation gave clear input is more convenient respect to one. obtained worth larger for statistical prove here presented results.
