LASER ADDITIVE MANUFACTURING AND WELDING WITH HYDROGEN SHIELD GAS

Using hydrogen in the shielding gas during laser welding is counter-intuitive to standard formulation design practices which often strive to limit or eliminate hydrogen from the shielding gas for laser welding (or from the welding arc and weld pool for other welding methods). The present disclosure...
