A method of forming a steel part is provided. The method includes the steps of coating a first steel plate to obtain a first precoat upon the first steel plate so as to define a first base, a first intermetallic alloy layer on the first base and a first metal alloy layer on the first intermetallic alloy layer. On a first face of the first steel plate the first metal alloy layer is removed in a first area of the first steel plate, while at least part of the first intermetallic alloy layer in the first area remains. A second steel plate is coated to obtain a second precoat upon the second steel plate so as to define a second base, a second intermetallic alloy layer on the second base and a second metal alloy layer on the second intermetallic alloy layer. On a second face of the second steel plate, the second metal alloy layer is removed in a second area of the second metal plate, while at least part of the second intermetallic alloy layer in the second area remains. After removal of the first and second metal alloy layers, the first steel plate is butt-welded to the second steel plate at the first and second areas to form a welded blank. A heat treatment is performed on the welded blank. The welded blank is shaped after the heat treatment into the steel part. A steel part is also provided.

Plate consisting of a steel substrate (1) and a precoat (2) consisting of a layer of intermetallic alloy (3) in contact with said substrate, topped by a layer of metal alloy (4), characterized in that, on at least one precoated face of said plate, an area (6) situated at the periphery of said plate has said metal alloy layer removed.

A brazing assembly for a roof laser-brazing system includes: i) a brazing bracket configured to be mounted to a brazing robot in a brazing section; ii) a laser head mounted to the brazing bracket and configured to emit a laser beam to irradiate a bonding portion of a side panel and a bonding portion of a roof panel; and iii) a wire feeder mounted to the brazing bracket and configured to supply a filler wire to a focal position of the laser beam.

A coated metal heat pipe, method of joining the heat pipe to a block of fissionable uranium, and the fissionable block with one or more embedded heat pipes are provided for use in a nuclear space reactor. The heat pipe wall is composed of a nickel-based alloy, stainless steel, or refractory metal. A sandwich of successive copper, molybdenum and copper layers cover the heat pipe. This interface manages the shear stresses from differential thermal expansions of the core and heat pipe materials. The molybdenum also serves as a uranium diffusion barrier. After inserting each coated heat pipe into openings in the block of fissionable material, a hydraulic ram, hot isostatic press, or other means apply selected external heat and pressure in an inert environment to complete the metallurgical bond, where the copper interface layers are brought up to a near liquidus temperature.

This disclosure provides systems, methods, and apparatuses, including computer programs encoded on computer storage media, that provide for welding techniques for manufacturing robots, such multipass welding techniques for welding robots. For example, the welding techniques may enable generation of weld instructions based on a welding fill plan. The instructions may be generated based on a bead model or a table that indicates a wire feed speed, a travel speed, or a voltage. As another example, the techniques may enable generation of weld instructions based on the one or more dimensions of a seam. As another example, the techniques may enable generation of a joint model of a cross-section of a seam to be welded. The joint model may be generated based on a combination of a plurality of feature components to generate the joint model of the seam. Other aspects and features are also claimed and described.

A method for laser soldering includes selecting a copper-containing material as a filler material, supplying the filler material at a butt joint of two components, and melting the filler material in a main process zone by means of laser radiation in an advancement direction. The filler material in the main process zone is melted by means of laser radiation of a wavelength H in the blue or green spectral range with 400 nmH600 nm.
