HYBRID WELDING
hybrid welding is much faster and the energy input per unit length is much lower; therefore the thermal distortion is much lower. Furthermore, you can reduce the number of weld beads significantly and so reduce the production time.’ Aside from improved joint gap tolerance and
the elimination of hot cracks, hybrid laser welding also facilitates other improvements in weld quality. As the weld pool is larger and the freezing and cooling process immediately aſter welding is slower than in laser welding, gas bubbles in the weld pool can escape more readily before the weld freezes. Tis can reduce weld porosity content. Te production of large-scale welds requires
heavy-duty machinery. Trumpf recently opened a facility in Austria where a hybrid laser welding head from Fronius International is capable of joining sheets weighing 20 tons to produce huge frames for press brakes. Te welds, which are up to 8mm deep, support loads of up to 320 tons of press force, repeatedly, over the lifetime of the brake press. Hybrid welding is a quicker process, because only a single pass is required, compared with

conventional arc welding where you would build up the weld a bead at a time. Te system can join more than 20 machine frames a week; the laser can also preheat the materials and, as the process is automated, quality assurance is more efficient. In ship building, large steel plates, which
are approximately 15mm thick and up to 30 metres long, are welded together. Hybrid laser welding is used as the gap between plates is simply too large to bridge using a conventional laser beam alone. Te laser delivers the power densities needed to achieve high welding speeds and deep welds. As mentioned, this subsequently reduces the heat input and distortion, while the MIG torch bridges the gap using filler wire. Mitsubishi Heavy
