A method includes removing a section of electrical insulation proximate an end of a tubing-encased conductor (TEC) to form an end of electrical insulation that is axially recessed relative to the end of the TEC. The method includes welding an end member to an outer surface of the outer tube at a weld joint that is axially between the end of the TEC and the end of the electrical insulation to protect the electrical insulation from heating damage from welding. The method includes replacing the section of electrical insulation proximate the end of the TEC by inserting a spacer into the end of the TEC between the outer tube and the electrical conductor after welding the end member to the outer surface of the TEC. A tool can be electrically connected to the electrical conductor and the tool can be welded to the end member.

A controller performs a first process of scanning a cylindrical irradiation region including a focused spot of laser light emitted from a laser light emitter to machine a flank face side of a workpiece to manufacture a cutting tool having a plurality of cutting edges arranged in line. In the first process, the controller scans the cylindrical irradiation region along a scanning path that has periodicity and changes a machining depth to form the plurality of cutting edges. The controller further performs a second process of scanning the cylindrical irradiation region including the focused spot of the laser light emitted in a direction different from an irradiation direction of the laser light in the first process to machine a rake face side of the workpiece.

A method of creating a cladded tool with a distributor including a feed mechanism and an energy source. The method includes providing a substrate and distributing particulate material from the feed mechanism onto the substrate. The particulate material includes agglomerated particles with diameters between 30 and 100 microns. The method also includes activating the energy source to produce a beam spot on the particulate material, the substrate, or both and at least partially melting the particulate material, the substrate, or both with the beam spot to form a bonded layer of particulate material on the substrate.

Provided is a mask including a mask frame including a base part in which cell openings are defined, and a coating part surrounding edges of the cell openings, covering at least a portion of an upper surface of the base part, and including a materials that is different from that of the base part, and unit masks on the mask frame, respectively corresponding to the cell openings, including a material that is different from that of the coating part, and in which openings are defined.

The present invention relates to a method of producing a composite rod from a braze material and a sheet of material comprising cermet. The method comprises scoring a surface of the sheet to produce at least one line of localised stress and subsequently causing the sheet to break along the line or localised stress, thereby to produce a plurality of cermet chunks. The cermet chunks can be combined with the braze material to produce the composite rod. In a particular embodiment, the sheet of material may be a used cermet cutting tip.
