A clamping apparatus for clamping shaped parts which are welded along a welding contour by irradiation with a laser beam, includes a first clamping plate used as a holder for a first shaped part, a second clamping plate which is designed to apply a clamping force to the first shaped part and a second shaped part arranged thereon, an outer clamping jaw including a recess and an inner clamping jaw arranged in the recess, which together form the second clamping plate, a passage gap for the laser beam formed in sections between the outer clamping jaw and the inner clamping jaw, and one or more fastening elements which connect the outer clamping jaw with the inner clamping jaw in sections and which bridge the passage gap; and further includes a mirror element arranged such that the laser beam is reflected onto a section of the welding contour.

The present invention provides polymer-metal composites free of adhesives and methods of making same. In particular, the present invention takes advantage of a unique metallic bonding surface created by exposure to a laser whereby micron-sized fragments are fixed to the metallic bonding surface such that a high strength bond with polymeric material is created upon exposure to a second laser.

It is provided an electronic control device including a resin molded body, a metal body, and an electronic component, wherein the resin molded body and a main surface of the metal body are bonded, and at least a part of a side surface continuous to the main surface of the metal body is in contact with a side contact portion provided in the resin molded body.

A composite including: (I) a fiber-reinforced composite material; and (II) a metal member joined and fixed to the fiber-reinforced composite material by welding. The fiber-reinforced composite material is composed of reinforcing fibers and a resin composition. The resin composition contains (A) a polypropylene-based resin and (B) a modified polyolefin-based resin. The polypropylene-based resin has a tensile modulus of not less than 1 GPa. The modified polyolefin-based resin is a modified polyolefin resin modified with at least one kind of monomer which is selected from carboxylic acid group-containing vinyl monomers and epoxy group-containing vinyl monomers. A weight ratio between (A) and (B) in the resin composition is 90:10 to 40:60.

A laser welded structure is formed by laser welding together a resin molded body formed from a thermoplastic polymer alloy containing a crystalline resin and an amorphous resin and a metal body made of a metal. A glass transition temperature of the amorphous resin is lower than a melting start temperature of the crystalline resin.

An electric valve can be further miniaturized while reducing the number of manufacturing man-hours. The electric valve contains: a motor including a stator member and a rotor member that displace a valve body, and a housing for accommodating the motor. The housing is formed by joining a heat generation portion formed of a first material to a heat receiving portion formed of a second material. The light transmittance in the first material is lower than the light transmittance in the second material.

A bonding structure manufacturing method for manufacturing a bonding structure in which a first member and a second member are bonded is provided with: a step for forming a perforation with an opening in the surface of the first member and forming a protrusion that protrudes into the inner circumferential surface of the perforation; a step for disposing the region of the first member where the perforation is formed adjacent to the second member; and step for filling and curing the second member in the perforation of the first member by irradiating a laser on the region of the first member where the perforation is formed from the second member side.

The present disclosure relates to a battery module that includes a housing having a first absorptive material configured to absorb a laser emission, a cover having a second absorptive material configured to absorb the laser emission, and a collar configured coupled to the housing and coupled to the cover via a laser weld. The collar includes a transparent material configured to transmit the laser emission through the collar and toward the housing or the cover.
