Welding Inconel 718
This is our 4000 watt Co2 laser slicing process. We can cut Stainless Steel and alloys to .five hundred”, Steel and metal alloys to .750″ and aluminum to .375″. Equally our devices have big bed dimensions, just one is sixty” x 120″ and the 3000 watt is seventy eight” x 157″. Equally devices have automatic loading and shuttle tables for prototyping to manufacturing.
