摘要： A contact tip suitable for electric arc welding has a consumable electrode. The contact tip has a body which defines a bore through which the electrode is able to pass to enable electric current from a welding power supply to be transferred from the body to the electrode. The body, in part of the length of the bore between an inlet end and an outlet end, has at least one region (herein referred to as a primary contact region) at which the body is adapted to enable primary electrical contact with the electrode, and along a remainder part of the length of the bore, the body is adapted such that any secondary contact between the body and the electrode along the remainder part does not substantially short circuit the primary electrical contact in the primary contact region of the bore.

摘要： The invention relates to blind rivets and to methods of joining therewith. The method of the invention is suitable for joining two or more workpieces with a blind rivet. The method includes the first step of positioning a blind rivet at a point of overlap of two or more workpieces, the blind rivet including a rivet body and a mandrel. The next step involves rotating the mandrel about a longitudinal axis thereof and contacting the mandrel with the overlapping workpieces, wherein the mandrel is rotated at a speed to cause plasticization of the overlapping workpieces. The method then involves causing the mandrel to penetrate through the plasticized overlapping workpieces and form an aperture therethrough. A further step of the method involves capturing a portion of the overlapping workpieces that is displaced upon the penetration of the mandrel and securing the rivet body within the aperture to join the overlapping workpieces. The invention also includes a workpiece penetrating and joining blind rivet. The blind rivet includes a rivet body including a shank having a first end, a second end and an axial passage extending through the shank between the first and second ends. Also included is a mandrel including a shaft positioned within the axial passage and a head at one end of the shaft for contacting a workpiece wherein the mandrel is configured so that when contacting the workpiece, being rotated about a longitudinal axis thereof at a speed to cause plasticization of the workpiece and being caused to penetrate through the plasticized workpiece the mandrel cores a portion of the plasticised workpiece, displaces the portion from the workpiece and forms an aperture in the workpiece.
