High-productivity hybrid induction heating/welding assembly
In certain embodiments, inductive heating is added to a metal working process, such as a welding process, by an induction heating head. The induction heating head may be adapted specifically for this purpose, and may include one or more coils to direct and place the inductive energy, protective structures, and so forth. Productivity of a welding process may be improved by the application of heat from the induction heating head. The heating is in addition to heat from a welding arc, and may facilitate application of welding wire electrode materials into narrow grooves and gaps, as well as make the processes more amenable to the use of certain compositions of welding wire, shielding gasses, flux materials, and so forth. In addition, distortion and stresses are reduced by the application of the induction heating energy in addition to the welding arc source.
Hot-pressed member and manufacturing method therefor
A hot-pressed member is formed using a tailored blank material obtained by butt joining respective ends of two or more coated steel sheets. The hot-pressed member has two or more sites formed by the respective coated steel sheets and at least one joining portion between the sites. Depending on a type of a coated layer of each of the coated steel sheets, t.sub.w/t.sub.0 is appropriately controlled where t.sub.w is a thickness of a thinnest portion in the joining portion and t.sub.0 is a thickness of a thinnest site of the sites. A tensile strength of each of the sites is 1180 MPa or more.
