Abstract: A method of forming a body by deposition of a weld material comprises providing a welding head (12), providing a foundation (52) upon which the body is to be formed. A weld material is supplied from a supply (22). The welding head (12) and the foundation (52) are connected to a supply of electricity to form an arc between the welding head (12) and the foundation (52) to melt the material. A raised member (74) is provided on the foundation (52). The method further includes manipulating the foundation (52) and the welding head (12) relative to each other to deposit the material on the raised member (74) and form the body.

Abstract: A method of forming a hollow section body by deposition of a weld material includes the steps of providing a welding head 12 and a turntable 36 on which the body is to be formed, supplying a weld material to the welding head 12, the weld material to be deposited on the turntable 36 and connecting the turntable 36 and the welding head 12 to a supply of electricity to form an arc between the welding head 12 and the turntable 36 or the body to melt the material. The method includes the steps of manipulating the turntable 36 and the welding head 12 relative to one another to deposit material to form a first wall 40, manipulating the turntable 36 and the welding head 12 relative to one another to deposit material for form a second wall 42 extending from an angle to the first wall 40 and manipulating the turntable 36 and the welding head 12 relative to one another to deposit material to form a third wall 44 joining the first two walls, to form a hollow section body.

Abstract: A calcined powder of co-precipitated mixed oxides of tin and antimony is used as a YAG laser marking additive. The additive is designed to impart little to no color to the plastic in which it is incorporated but to provide a high contrast dark marking after being exposed to a YAG laser.

Abstract: Apparatus for forming a component by the deposition of a weld material includes a welding head 12 providing a weld material 24 to be deposited on a substrate, in order to build up the component. A flow of current is provided between the welding head 12 and the substrate to thereby melt the weld material 24 and form a molten weld pool in the substrate. The substrate is moved relative to the welding head and the molten weld material is gradually deposited upon the molten weld pool to build up the components layer by layer. The molten weld pool thus effectively moves along the substrate. A supply of argon at cryogenic temperatures is provided just behind the molten weld pool to quench the weld material, thus refining and improving its crystal structure.

Abstract: An apparatus for forming a component, for example for an aerospace engine, includes a welding head 12 which supplies a weld material 24 to be deposited on a substrate 56 in order to build up the component. A flow of current is provided between the welding head 12 and the substrate 56 thereby melting the weld material and forming a molten weld pool in the substrate. A coil 50 is located above the weld pool and is provided with an alternating current thereby inducing an alternating magnetic field in the region of the weld pool to exert a force upon the molten substrate of the weld pool. This improves the crystal structure and therefore the properties of the resulting component.

Abstract: Apparatus for forming a workpiece by deposition welding comprises a welding head having at least two wires of weld material extending therethrough. Each wire is formed of weld material such that an electric current is passed therethrough, the wires become molten and form the weld material of the workpiece.

Abstract: A method for forming a body by deposition of a weld material comprises providing a welding head (12), and providing support means (34) to support the body. The welding head (12) and the support means (34) are connected to a supply of electricity to form an arc between the welding head (12) and the support means (34) to melt the weld material. The welding head (12) and the support means (34) are manipulated relative to each other to deposit the weld material and form a carrier member of the body. The carrier member is formed to carry a projecting member. The carrier member has a first portion (52) of a first predetermined thickness and a second portion (54) of a second predetermined thickness, the second predetermined thickness being greater than the first predetermined thickness. A projecting member is provided on the first portion.

Abstract: Alloy and cast alloy product ideally suited for use as a component in a vehicle frame or subframe, i.e., body-in-white, comprising an alloy consisting of about 2.00 to 5.00 wt. % magnesium, up to approximately 0.30 wt. % silicon, approximately 0.20 to 1.60 wt. % manganese, up to approximately 1.00 wt. % iron, and between about 0.10 to 0.30 wt. %, zirconium, the balance substantially aluminum and incidental elements and impurities. The aluminum/magnesium alloy is typically solidified into ingot derived working stock by continuous casting or semi-continuous casting into a shape suitable for remelt for casting, which shape is typically an ingot billet. Excellent mechanical properties are obtained from a cast product that is not subjected to high temperature heat treating operations subsequent to casting.
