A thermal module structure includes an aluminum base having a heat pipe receiving groove formed on one side thereof; a heat dissipation unit including a plurality of radiation fin assemblies or heat sinks and being provided with a first heat pipe receiving section; a plurality of heat pipes made of a copper material and respectively having a heat absorption section and a horizontally extended condensation section; and a copper embedding layer provided on surfaces of the heat pipe receiving groove and the first heat pipe receiving section. The aluminum base and the heat dissipation unit are horizontally parallelly arranged. The heat absorption sections are fitted in the heat pipe receiving groove, and the condensation sections are extended through the first heat pipe receiving section. With the copper embedding layer, the aluminum base and the heat dissipation unit can be directly welded to the heat pipes.

A method of manufacturing a punch, such as a socket punch, using wire EDM with at least six steps. The method involves forming a blank, holding the blank with an adapter, machining grooves in the blank, manufacturing a side relief of a working portion using wire EDM, milling the working portion to a final size, and forming a cone point on the end of the working portion. The method allows the punch to be manufactured more quickly and from a CAD model, therefore removing the need for over-specialized equipment and improving manufacturing times.

In some embodiments, a method may bond titanium to an intermediate alloy. The method may include layering a portion of an intermediate alloy onto a portion of titanium. The method may include focusing a controlled heat source on a spot of the intermediate alloy to form a weld pool in the intermediate alloy at the spot. The method may include superheating the intermediate alloy in the weld pool above the melting point of the intermediate alloy but below the melting point of titanium such that liquid intermediate alloy contacts the surface of the portion of the titanium heating the portion of the titanium. The method may include diffusing the portions of titanium and intermediate alloy together such that upon the intermediate alloy cooling below the melting point of the intermediate alloy the portions of the intermediate alloy and titanium are bonded forming a weldment.

In a method for the production of a seamless, multilayered tubular product, a further layer is applied through hardfacing on a base layer of a round or polygonal block, with the further layer made of a metallic material which is different than a metallic material of the base layer. The round or polygonal block with hardfaced further layer is hot formed to produce a tubular product with reduced wall thickness and outer perimeter in one or more stages. A diffusion layer is established between the base layer and the further layer through heat treatment before hot forming and/or after hot forming, thereby producing a thickness of the diffusion layer of at least 5 m with the proviso that the thickness of the diffusion layer is 0.1% to 50% of a thickness of the further layer, with the thickness of the further layer being equal to or greater than 100 m.
