A laser welding apparatus is provides that includes: a support member including a heat generation portion which has a size that is limited to correspond to a size of a welding area of a plurality of plastic components and is made from a material that absorbs a laser beam and generates heat, and which generates heat of a temperature that is equal to or greater than a melting temperature of the plastic components; a laser beam irradiation unit for converging a laser beam to be transmitted through the plurality of plastic components, and irradiating the laser beam toward the heat generation portion through the plurality of plastic components; and a welding controller for causing a laser beam to be irradiated at the heat generation portion using the laser beam irradiation unit to thereby cause the heat generation portion to generate heat, and welding abutting faces of a welding area of the plurality of plastic components with heat that is generated.

A fiber-reinforced thermoplastic resin member welding method includes: heating, by a heating unit, a welding target portion in which plural fiber-reinforced thermoplastic resin members layered on top of each other, each of the plural fiber-reinforced thermoplastic resin members including thermoplastic resin as a main composition, and the thermoplastic resin including reinforcing fibers; applying pressure, by a pressure applying unit, to the welding target portion; and cooling, by a cooling unit, at least a surface of the welding target portion at the same time as when the welding target portion is being heated by the heating unit or after the welding target portion has been heated by the heating unit.

A method for manufacturing a fuel cell assembly includes: arranging an end face of a gas diffusion layer on a placement jig in a state abutting an end face of a resin frame; melting a part of the frame member and causing to penetrate into the gas diffusion layer by pressurizing the projecting part by way of a heat-transfer member, and heating the projecting part via the heat-transfer member by abutting a heating member against of the heat-transfer member; and solidifying the part of the resin frame having penetrated into the gas diffusion layer, in which an abutting position of the heating member relative to the heat transfer member is set in the melting step so that a central axis of the heating member is positioned more to a side of the gas diffusion layer than the central axis of the projecting part.

The plastic preheating arrangement for a plastic welding device comprises a support, at least one first preheating device and a pivoting arrangement with which the at least one first preheating device can be pivoted relative to a first surface of the support from a starting position into a preheating position. In this manner, an undercut of a first component can be circumnavigated and the first component can be heated by means of the first preheating device.

A process and apparatus (1) for packaging a product (P) arranged on a tray (4) is disclosed. The apparatus comprises a packaging assembly (8) configured for tightly fixing one or more film sheets to one or more trays. The packaging assembly includes a lower tool (22) defining a prefixed number of seats (23) for receiving the trays and an upper tool (21) facing the lower tool and cooperating with the upper tool to define a packaging chamber (24). The packaging assembly (8) is configured to operate at least in a first operating condition, where said packaging chamber (24) is open, and in a second operating condition, where said packaging chamber (24) is hermetically closed. First injection apertures (90) are positioned in corner regions of the seat and are configured to inject streams of gas in a direction substantially parallel to and above the flange (4c) of a tray (4) positioned in said seat. The process includes the step of activating injection of a plurality of streams of gas through said first apertures (90) in order to form a controlled atmosphere inside the tray before closing the tray with the film.

A method of manufacturing a workpiece includes heating a pre-formed blank of a first fiber reinforced thermoplastic material in an oven. A second fiber reinforced thermoplastic material is heated in an extruder. The second fiber reinforced thermoplastic material is extruded from the extruder, within the oven, to form an extrudate. The extrudate is positioned on the pre-formed blank of the first fiber reinforced thermoplastic material, within the oven, to form a composite blank. The extrudate may be formed into a shape before being positioned onto the pre-formed blank, after being positioned onto the pre-formed blank. The composite blank may then be transferred to a final shaping station.

The present invention relates to an apparatus and method for joining a longitudinal seam in a tube, to an apparatus and method of joining a longitudinal seam in a tube in a borehole, to an apparatus and method of repairing a tube and to a pig. In an aspect an apparatus is provided for joining a longitudinal seam in a tube. The apparatus (200) includes a spool (202) for progressively unwinding a coiled member (10) into an extended form (12). The member (10) transitions from a flat form when coiled (11) to a slit tube form when extended (12), in which form the member is resiliently biased. A joining device (214) is positioned downstream of the spool arranged to provide energy to a portion of the member in its extended form to cause heating so as to progressively join together the longitudinal edges of the slit tube as the member passes the joining device. A longitudinal seam (20) is thereby formed in the tube.

A minimally invasive surface attachment apparatus for non-penetrating mechanical attachment of components to a target surface includes a cartridge assembly and mounting assembly. Actuation of the cartridge assembly causes first and second exothermic reactants located between outer casing and the inner casing to come into contact and cause an exothermic reaction. This reaction liquefies a bonding material between the cartridge assembly and mounting assembly, allowing it to flow around the mounting assembly and onto a target surface creating a seal. Vacuum pressure will bind the mounting assembly to a target surface.
