Hybrid laser-MIG/MAG welding at ISI
Mrňa, Libor ; Novotný, Jan ; Šebestová, Hana ; Znášik, Samuel ; Gross, Jan ; Harašta, Jiří
Laser welds usually suffer from underfill defects because the welding is usually made without a filler wire. During the hybrid laser-MIG/MAG welding, the laser beam forms the melt pool, and the arc simultaneously delivers melted filler wire. The synergic interaction of both heat sources allows deeper penetration while the weld face is sufficiently filled and has the prescribed geometry. This contribution reports the issues of individual systems integration and presents already-made experiments.
