Huffman Corp. introduced model HP-245ACC, a laser welding system with a fully enclosed atmospheric welding chamber for welding in an inert gas environment. The system is designed for welding oxygen-sensitive or -reactive materials like titanium. The system can be configured with a variety of features like antechambers, inert gas handling and purification systems, oxygen and moisture sensors, and part-handling devices to match the end user’s specific needs. Applications include weld restoration on worn surfaces on a variety of turbine engine components like blades, vanes, shrouds, seals, and bladed disks or integrally bladed rotors. The system is also capable of 3-D freeform fabrication — welding successive layers of material to build up complex 3D components. (
