What's new about Hybrio™ technology?
ESAB's Hybrio™ hybrid laser welding technology combines the deep weld penetration and low heat input associated with laser welding with the excellent weld properties and superior gap tolerance of Gas Metal Arc Welding (MIG/MAG - GMAW). A radically new welding alternative, it produces extremely narrow and deep welds at very high travel speeds. In a single pass, the Hybrio™ process can often achieve what might require multiple weld passes using a conventional fusion welding process. Heat input to the part is reduced, as is the associated weld shrinkage and distortion that can make post-welding geometry unpredictable – and costly to repair.
Using MIG/MAG - GMAW in combination with a laser, the Hybrio™ process solves laser-only welding's limitations, concerning its ability to produce acceptable welds in joints with less than perfect fit-up between parts. This enables a widened, more robust process envelope by a factor of three compared to a conventional laser-only process. MIG/MAG - GMAW also allows users to add filler metal to adjust the weld's metallurgical properties and create beads and fillets, while the slower cooling rate reduces hardness. These features are especially beneficial when joining high performance carbon and stainless steels.
