A method for joining or machining, in particular a friction stir welding method, using an apparatus, in which a tool, in particular a friction stir welding tool, is driven via a spindle with a spindle axis. To achieve high process reliability, even when the method is applied in poorly accessible positions, an adapter, in particular an angle head, is arranged between the spindle and the tool so that the tool axis about which the tool rotates does not coincide with the spindle axis. A force acting on the spindle is measured and the method is controlled depending on the force measured at the spindle. The apparatus for joining or machining, in particular for friction stir welding, includes a headstock with a spindle, which can be rotated about a spindle axis and a tool, in particular a friction stir welding tool, which can be driven about a tool axis by the spindle.

The present invention provides a weathering steel for solid-state welding that forms an excellent weld when subjected to solid-state welding and has tensile properties equivalent or superior to those of high tensile strength steel, said steel having weathering properties superior to those of conventional weathering steel for welding, wherein the reliability of the weld is equivalent or superior to that of the parent material; and a weathering steel material for solid-state welding. Further, there is provided a solid-state welded structure that includes the weathering steel for solid-state welding according to the present invention, and a solid-state welding method for said weathering steel for solid-state welding. The weathering steel for solid-state welding having a steel composition comprises, in % by mass, C: 0.10 to 0.60% and P: more than 0.035 to 1.000%, with the remainder consisting of Fe and unavoidable impurities.

A dissimilar metal article may include a first metallic component including a first metal material, a second metallic component comprising a second metal material, and a transition joint provided between and bonding a first metallic component first end surface to a second metallic component first end surface. An additive flow material may be further provided to the dissimilar metal article to strengthen the joint between the first metallic component and the second metallic component.

A method of manufacturing a high-pressure fluid vessel includes forming a first portion of a high-pressure fluid vessel with a molding process. The high-pressure fluid vessel includes a stack of capsules. Each capsule includes a first domed end, a second domed end, and a semicylindrical portion extending between and connecting the first domed end to the second domed end. The method further includes forming a second portion of a high-pressure fluid vessel with the molding process. The second portion of the high-pressure fluid vessel is positioned adjacent to the first portion of the high-pressure fluid vessel. The second portion of the high-pressure fluid vessel is welded to the first portion of the high-pressure fluid vessel.

The invention relates to a work interface accessory, comprising an external body having a wall delimiting a recess for the introduction of a rotating portion of the friction stir welding head, an upper plate comprising fastening portions against the head, a central rotating shaft projecting to carry a work tool, the shaft comprising an internally toothed coupling sleeve to allow the shaft to be driven in rotation, when an externally toothed ring gear of the rotating portion of the head rotates in the sleeve.

A method for attaching a cover to a base includes coupling the cover to the base and welding the cover to the base using a friction stir welding tip. The method further includes pushing the cover against the base using a shoulder through which the friction stir welding tip extends.

The invention relates to tooling for holding parts in position to enable them to be friction welded together in order to construct a hollow structure, the tooling comprises: a framework made up of two frames for receiving the parts for welding together in their positions for forming the hollow structure, the parts comprising preformed parts and an intermediate section; shape-holder members for holding the hollow structure, associating backing thrust members and lateral grip members for gripping the outsides of the preformed parts; anvils suitable for being placed inside the set of preformed parts beside the section; and clamping means operable to take up a clamping position in which they cause opposing thrust to be applied against the anvil and the inside face of a preformed part, its part itself bears against the shape-holder members.

A panel joint structure suppresses stress concentration on a flange corner section-side end-portion of an adhesive during application of a peeling load. A first panel member includes a panel body section, a corner section, and a first flange section. A second panel member is arranged to oppose the first flange section. A joint section joins the first flange section and the second panel member in a contact state thereof, and an adhesive continuously provided in a longitudinal direction of the corner section adheres the first flange section to the second panel member. The first panel member includes a load transmission section near a joint section, and the load transmission section is provided between the panel body section and the first flange section, and an angle θ2 thereof that is defined with the panel body section is larger than an angle θ1 defined by the panel body section and a portion in a short direction of the first flange section. A flange distal end-side end-portion of the load transmission section in the short direction of the flange section is disposed in a region between a corner section-side end-portion and a distal end-side end-portion of the joint section in the short direction of the first flange section.
