    Abstract: Face sheets are bonded to honeycomb core material by applying brazing material to a side surface of one of said face sheets, placing one side of the honeycomb core material against the side of the aforesaid face sheet covered with brazing material and the other face sheet against the other side of the honeycomb core material, heating the assembly to melt the brazing material, and thereafter permitting the assembly to cool. Capillary action causes flow of the brazing material from the face sheet initially covered therewith to the other face sheet when the brazing material is melted.

    Abstract: A method for joining well and other oilfield tubulars by amorphous bonding comprises the steps of positioning a body of amorphous material (16) between adjacent and surfaces of a pair of oilfield tubulars (3, 4) that are to be joined and using induction heating to melt the amorphous material and create on cooling a metallurgical bond between the tubulars (3, 4). Throughout the heating and bonding process the tubulars (3, 4) are fixed in axial alignment with each other using clamp means which include a mandrel (1) which is inserted into the interior of the tubulars (3, 4) so that the bonding process can be performed in a sealed chamber (17, 18) which is filled with an inert gas.

    Abstract: A method of making an expanded metal sandwich structure includes cleaning at least two metal superplastic core sheets to remove metal oxides and residues that would interfere with diffusion bonding of the sheets. The core sheets are placed face-to-face and a gas pressure line fitting is inserted between one edge and is welded into place. The fitting has a through bore through which gas can flow under pressure into the space between the core sheets. The core sheets are pressed together and laser welded together into a core pack along lines which will form junction lines between the core sheets when the core pack is superplastically expanded. The core pack and the two metal face sheets having superplastic characteristics are each chemically cleaned, and the face sheets are placed over and under the core pack. An envelope gas fitting is placed between the face sheets and is welded in place while seal welding around the entire peripheral edges of the face sheet and the core pack to produce a sealed envelope pack with gas fittings into the core pack and into a face sheet zone between the face sheets and the core pack. A gas supply tube is connected to each of the fittings and air and moisture is purged from the packs by flushing with dry argon. The packs are pressurized to a low pressure with argon to maintain separation of the sheets while heating to prevent premature bonding. The full pack is placed in an internal cavity of a heated die and is raised to superforming temperatures. Forming gas is injected to inflate the envelope pack to the interior walls of the cavity and to inflate the core pack to the envelope pack and to diffusion bond the face sheets to the core sheets.

    Abstract: A two-sheet superplastically formed/diffusion bonded panel is made with a forming die assembly in which forming cavities are held in a flexible retaining sheet that floats in a forming box. A gas passage is provided through the box behind the cavities and the retaining sheet so that the cavities and retaining sheet are forced toward a rigid face sheet forming die element when pressurized gas is introduced. A face sheet and a reinforcing sheet sealed together around their edges, except for a gas passage to provide pressurized gas between the two sheets, are placed between the face sheet die and the forming die elements positioned in the box. The sheets are then heated and pressurized gas is applied between the sheets to cause the face sheet to move into contact with the face sheet die element while the reinforcing sheet superplastically deforms into the cavities supported by the retaining sheet to form ribs. After the ribs are formed in the reinforcing sheet, the pressure between the face and reinforcing sheets is reduced and the pressure in the box behind the cavity retaining sheet and die cavities is increased so that the formed sheet is moved against the face sheet for bonding. For dimple, as opposed to rib reinforced parts, dimples are created in a grid by shaped blocks facing the reinforcing sheet, which blocks are attached at their base to a flexible retaining sheet acted upon by pressurized gas in the gas chamber.

    Abstract translation: 两片超塑性/扩散接合面板用成形模组件制成，其中成型腔保持在浮动在成型箱中的柔性保持片中。 气体通道设置在空腔后面的箱体和保持片上，使得当加压气体被引入时，空腔和保持片被迫朝向刚性的面片成形模具元件。 除了在两片之间提供加压气体的气体通道之外，围绕它们的边缘密封在一起的面片和加强片被放置在面片模具和定位在盒子中的成形模具元件之间。 然后将片材加热，并且在片材之间施加加压气体，使得面片移动成与面片模具元件接触，同时加强片材超塑性变形到由保持片材支撑的空腔中以形成肋条。 在加强板中形成肋之后，面和加强片之间的压力降低，并且腔保持片和模腔之后的盒中的压力增加，使得所形成的片材抵靠面板移动以进行粘结。 对于凹坑，与肋加强部件相反，通过面向增强板的成形块在网格中形成凹坑，该块体在其基部附接到在气体室中受加压气体作用的柔性保持片。
