An additive manufacturing system includes an energy source and a material delivery device. The energy source is configured to direct an energy beam toward a component to form a melt pool. The material delivery device is configured to feed a wire toward the melt pool to deposit material on the component. In some examples, the material delivery device is configured to discharge a current to the wire to disengage the wire from the melt pool. In some examples, the material delivery device is configured to measure an arc voltage between the wire and the component.

A method of joining dissimilar metal, golf club components, and particularly golf club bodies, hosels, and faces, using a projection resistance welding process is disclosed herein. The method may include the step of applying an interlayer material before the projection resistance weld process occurs.

A design for tank fabricating equipment and system comprises a frame supporting opposing arms for supporting one or more tank shells. The opposing arms pivotally engage opposing sides of the tank shells to force them into a circular cross-sectional shape. The arms are provided with rollers for aligning the tank shell with adjacent components during fabrication. In some embodiments, the rollers are provided with a circumferential channel to accommodate welding seams and to ensure alignment of butt joints.

Provided herein are manufacturing methods, e.g., comprising: (1a) forming a layer, including: depositing a starting material including a mixture of a metal and a sacrificial material; and applying a laser beam to the deposited starting material to consolidate the deposited starting material and form the layer; (1b) optionally repeating (1a) one or more times; and (1c) at least partially removing the sacrificial material to form a porous metal part.

To obtain a pressure tank that achieves a high manufacturing efficiency and does not hamper storage of an open/close portion such as a vacuum valve in a pressure tank. A pressure tank of the present invention includes: a tank body having at least one penetrating slit-shaped mortise and having a space formed inside the tank body; a reinforcing member having a tenon portion formed at an end thereof so as to be directed in one direction, and having an electric field relaxation portion on a side opposite to the tenon portion, the reinforcing member being attached to an inner wall surface of the tank body with the tenon portion inserted into the mortise; and a welding portion sealing and fixing the mortise and the tenon portion with no gap therebetween, the welding portion being formed by melting an end of the tenon portion from outside of the tank body.

Angled, single laser weld and a method of forming an angled, single laser weld including arranging a first and second faying surfaces of a first and second component adjacently to form an interface between the components; irradiating at least one of the first and second components at the interface with a laser, wherein the first faying surface defines a plane formed at an angle alpha in the range of +/−5 degrees to 60 degrees from an axis A perpendicular to the first front surface and the second faying surface matches the first faying surface; and forming a junction at the interface with an hourglass shaped weld.

Disclosed in the present invention is a manufacturing method for a carbon steel and austenitic stainless-steel rolling clad plate, comprising the steps of: (1) obtaining a blank material of a carbon steel layer and a blank material of a stainless-steel layer; (2) assembling blank materials; (3) cladding and rolling; (4) cold rolling; (5) first annealing; and (6) second annealing. The carbon steel and austenitic stainless-steel rolling clad plate has two unique annealing processes, so that the clad plate has the performance advantages of the austenitic stainless-steel and the carbon steel. In addition, further disclosed in the present invention is a carbon steel and austenitic stainless-steel rolling clad plate manufactured by this method.

A high strength and corrosion resistant ferrochrome alloy bulk is disclosed, which comprises, in weight percent: 30-68% Cr, 1.5-8% Ni, 1.6-6% C, and the balance Fe and incidental impurities, of which a Fe/Ni ratio is in a range from 5 to 10 and a Cr/C ratio is in a range between 10 and 33. Experimental data reveal that, samples of the high strength and corrosion resistant ferrochrome alloy bulk all possess hardness above HV400 and excellent corrosion resistance due to the high content of Cr. As a result, experimental data have proved that the high-strength and corrosion-resistant ferrochrome alloy bulk of the present invention has a significant potential to replace conventional high-strength stainless steels, so as to be widely applied in various industrial fields, e.g., aviation, transportation, marine facility components, chemical equipment and pipe fittings, engine parts, turbine blades, valves, bearings, building materials, and so on.
