In some aspects, material processing head can include a body; an antenna disposed within the body; a first tag, associated with a first consumable component, disposed within a flux communication zone of the body at a first distance from the antenna, the first tag having a first resonant frequency; and a second tag, associated with a second consumable component, disposed within the flux communication zone of the body at a second distance from the antenna, the second tag having a second resonant frequency that is different than the first resonant frequency, where the first and second resonant frequencies are tuned based upon at least one of: i) a difference between the first distance and the second distance; or ii) a characteristic (e.g., shape) of the flux communication zone in which the first tag and/or the second tag is disposed.

A plumber's heat shield comprises an arcuate preferably metallic shell attached to a spring-clamp by means of an obedient shaft which enables the heat shield to be moved to any position relative to the spring-clamp. The arcuate shell is preferably formed from aluminum or other material having high infrared reflectivity. The obedient shaft is preferably formed from helically-wound steel spring outer sheath surrounding a ductile copper wire core. The spring steel outer sheath prevents the ductile copper wire core from being bent at too sharp of a radius (which would cause the ductile core to work-harden and fracture) while at the same time protecting the ductile copper wire core from the open-flame of the soldering torch.

In some aspects, consumables for a material processing head can include a body that is substantially axially symmetric about a central longitudinal axis; and a ring-shaped data tag attached to the body, the data tag having a central axis that is substantially coaxial to the central longitudinal axis of the body, the data tag having a conductive coil formed around the central axis of the data tag.

A torch for a welding or plasma cutting operation configured to provide information. The torch includes a torch body. The torch also includes indicators coupled to the torch body and control circuitry coupled to the indicators and configured to provide data relating to the welding or plasma cutting operation to the indicators.

Hybrid bonded turbine rotors and methods for manufacturing the same are provided. A method for manufacturing a hybrid bonded turbine rotor comprises the steps of providing turbine disk having a rim portion comprising a live rim of circumferentially continuous material and a plurality of live rim notches in an outer periphery of the turbine disk alternating with a plurality of raised blade attachment surfaces defining the outer periphery; providing a plurality of turbine blades, each of which comprising an airfoil portion and a shank portion, the shank portion having a base surface; metallurgically bonding a compliant alloy material layer to either or both of the raised blade attachments surfaces of the turbine disk and the base surfaces of the blade shanks; and linear friction welding the plurality of blades to the turbine disk so as to form a bond plane between the raised blade attachments surfaces of the turbine disk and the base surfaces of the blade shanks, the compliant alloy material layer being disposed at the bond plane.

A dry storage systems for radioactive nuclear waste materials may include a double-walled canister system. The canister system may include a canister having a tubular inner shell defining an internal cavity for storing nuclear waste material, a first lid sealably welded to a first end of the inner shell, a primary base plate defining a peripheral edge portion and having an annular closure flange, and an annular full thickness butt weld formed at an abutment joint between the annular closure flange and a second end of the inner shell. The inner shell, first lid, and first end closure may collectively define a sealed primary pressure retention barrier. A tubular outer shell may adjoin the inner shell. The outer shell may be welded to the canister to form a hermetically sealed secondary pressure retention barrier.
