The invention relates to a method and to a device for welding together two joining partners by means of friction stir welding, which prevents the joining partners being contaminated by welding residue. The method comprises the following features: a welding head that can be integrated into any machine, said welding head being in the form of a spindle drive driven by a drive unit, comprising a mounting flange for securing the device assisting the welding process, and a clamping system for receiving a frustoconical-shaped tool having a welding and smoothing shoe for guiding a welding pin (11), a device (17) integrated into the welding and smoothing shoe for grinding the waste produced during the welding process, the waste produced during welding is then removed by means of one inlet channels for fluid arranged in the upper and/or lower area of the frustoconical-shaped tool for the fluid (20, 18) and a suction channel (19).

Methods of screening a polycrystalline diamond element for suitability for electrical discharge machining (“EDM”). The method includes providing a PCD element including a plurality of bonded diamond grains, determining at least one characteristic of the PCD table correlated to electrical conductivity of the PCD element, and EDM the PCD element if the value of the at least one characteristic correlates to an electrical conductivity above a threshold value.

A method for producing a primary material for a cutting tool, for example a primary material for a saw blade or a saw band, in which a band-shaped carrier of a metal carrier material and a wire of high-speed steel are continuously brought together along a lateral edge of the band-shaped carrier and transported into a welding device and the band-shaped carrier is welded to the wire along the lateral edge of the carrier to produce a bimetal band. The band-shaped carrier and the edge wire are welded to one another by at least a first welding device, which is arranged on one side of the band-shaped carrier, and at least a second welding device, which is arranged on the opposite side of the band-shaped carrier.

Disclosed is a coupling member that enables a joint between a wooden member and a mating member to absorb vibration energy, and a method for producing the same and a joint structure using the same. The metal coupling member is embedded in the wooden member. The wooden member is connected with a mating member by the coupling member. The coupling member includes a metal rod-like main body portion to be embedded in the wooden member, and an inner rod portion protruding from the main body portion. The inner rod portion axially extends from a protruding portion thereof to a predetermined depth in the main body portion, has a periphery separated from the main body portion to allow axial displacement of the inner rod portion relative to the main body portion, and is integrally connected to the main body portion at the deepest part thereof.

An anchoring assembly for anchoring a liner of a cured lining material arranged to be applied in liquid form to a metal object provided with the anchoring assembly, the anchoring assembly including an elongated mounting pin and a ferrule provided at a first end thereof, wherein the pin is arranged to be mounted at the first end to the metal object, the anchoring assembly further including a plurality of spaced anchor fins connected to the pin at a second end and extending radially outward relative to the pin, wherein the ferrule includes a radially outwardly extending place holder part arranged to be held by a ferrule holder during mounting of the pin at the first end to the metal object.

Embodiments of the present disclosure provide a mask assembly and a manufacturing method thereof. The mask assembly includes: a frame; a mask provided with a mask area and connection areas positioned on opposite sides of the mask area; and a plurality of first connection parts in each connection area, wherein the plurality of first connection parts in each connection area are arranged in M rows and N columns, each row includes a plurality of first connection parts, each column includes at least one first connection part, and in the same connection area, the first connection parts of any two adjacent rows are arranged in a staggered manner, where each of M and N is an integer larger than 1, and the mask is fixed to the frame via the plurality of first connection parts.

A mount system and method of manufacture for e.g. a machine vision camera is disclosed. The mount system comprises a rectangular base, a lower clamp disc, an upper clamp disc, a tilting plate, an expansion clamp, and an O-ring. The expansion clamp comprises a tapered head screw and an expandable mandrel, both typically made of stainless steel. The mount system facilitates improved machine vision by enabling effective mounting of machine vision cameras in smaller spaces and/or spaces requiring unusual angles and intricate positioning. The mount system is also advantageous in inhospitable environments having harsh environmental factors. The mount system is also easier for machine vision personnel to learn and understand.

A method for manufacturing a cutting tool having a rake face, a flank face, and an edge having a ridge line interconnecting the rake face and the flank face, wherein on the flank face there is a cutting edge region from the ridge line of the edge to a point A away therefrom on the side of the flank face by a distance X, the method comprising producing and processing the flank face with a laser, the producing and processing being producing and processing the cutting edge region along the ridge line of the edge with a first laser beam having a depth of focus equal to or deeper than a width of the cutting edge region when the distance X is the width of the cutting edge region, the distance X being 0.2 mm or more and 5 mm or less.

A non-weldable workpiece may be affixed to a weldable workpiece by friction stirring the weldable workpiece to plasticize and extrude at least a portion thereof into a recess in the non-weldable workpiece. The weldable workpiece may then be welded to a body of a downhole tool to enable the welding of a non-weldable workpiece onto a body to increase the wear-resistance of the body.

The invention relates to a method and a laser machining device 10 for machining a workpiece 13. The laser machining device 10 has a laser 11 for generating a laser beam 12, which is deflected by way of a deflecting device 15 in accordance with a pattern defined by a control unit 14 and is directed onto a workpiece surface 17 of a workpiece 13, which surface is to be machined. The point of impingement 18 of the deflected laser beam 12b on the workpiece surface 17 is guided along at least one spiral path within a circular hatched area 16. The spiral path 19 is characterized by spiral path parameters. One spiral path parameter is the line spacing a between neighboring points of intersection P of the spiral path 19 with an axis running through the center point M of the spiral path 19.
