A friction welding machine for radiating fins is disclosed, which mainly uses a moving unit to drive a friction joint unit to approach the plurality of radiating fins, and a friction rod provided in the moving unit rotates at a high speed to penetrate the radiating fins. The radiating fins are then welded together through the heat generated by high-speed rotation friction to achieve the purpose of improving the welding quality of the radiating fins and reducing the cost.

In an example, a showerhead pedestal assembly for a substrate processing chamber is provided. The showerhead pedestal assembly includes a faceplate. A platen is disposed within the faceplate and includes a heater element extending through at least one groove in the faceplate. The at least one groove is profiled to accept at least one portion of the heater element. A periphery of the platen is joined to an interior surface of the faceplate by a friction stir welded joint.

The disclosure provides an aluminized composite including a base material. The aluminized composite may also include a diffusion layer disposed over the base material. The aluminized composite may further include an aluminum material disposed over the diffusion layer.

A machine component includes a first region having a first linear expansion coefficient, and a second region having a second linear expansion coefficient greater than the first linear expansion coefficient and joined to the first region. A region including an outer periphery of an interface between the first region and the second region is inclined toward the second region side over the entire periphery. On a surface of the first region, a groove is formed to extend along the outer periphery of the interface.

A device for performing a method for producing a lamination pack, wherein in the method laminations are cut from an electric strip or sheet; the laminations are placed on top of each other to form a lamination stack; the laminations are connected by material fusion to each other by: locally plasticizing a material of the laminations in an edge region of the laminations by generating friction heat by a tool; mixing the locally plasticized material, at least of the laminations neighboring each other, with the tool; and allowing the plasticized material to cool and fuse the laminations in the edge region to form the lamination pack. The device has a punch press and/or a receptacle for one or a plurality of lamination stacks. The device further has a welding tool that is rotatably driven about an axis of the welding tool and moveable transverse to the axis of rotation.

A method of sealing a hole in a wall of a hollow structure comprises providing a sealed chamber that is external to the structure and that is in fluid communication with an internal space of the structure via the hole. The structure may be a pipe-in-pipe structure and the internal space may be an annulus between outer and inner pipes. Fluid flows through the hole into or out of the chamber as the pressure and/or composition of fluid in the internal space is adjusted. Then, a plug is spun and friction-welded into the hole. The plug is inserted into the hole from within the chamber.

The invention relates to a device and a method for changing the welding direction of the welding shoulder of a system for a friction stir welding process virtually without delay when required by the geometric arrangement of the joint partners to be welded or by a material unevenness, having the following method features: a) a main part (1) with a horizontally movable bridge support (5) has a friction welding head (12) which can be vertically adjusted together therewith and which has a pin receiving area (13) for mounting and driving a welding pin tip (14), wherein the welding shoulder (18) has a welding shoulder receiving area (17) which is supported at multiple points, and b) the welding shoulder receiving area (17) can be adjusted to any angle of attack relative to the joint partners by means of different push-pull rods (16) during the welding process.
