5 results about "Forge welding" patented technology

Forge welding (FOW) is a solid-state welding process that joins two pieces of metal by heating them to a high temperature and then hammering them together. It may also consist of heating and forcing the metals together with presses or other means, creating enough pressure to cause plastic deformation at the weld surfaces. The process is one of the simplest methods of joining metals and has been used since ancient times. Forge welding is versatile, being able to join a host of similar and dissimilar metals. With the invention of electrical and gas welding methods during the Industrial Revolution, manual forge-welding has been largely replaced, although automated forge-welding is a common manufacturing process.

PendingCN121447388AChemical compositionIngot
The invention relates to a method for improving the surface quality of nickel-based alloy strip foil, and belongs to the technical field of high-temperature alloy processing and preparation. Remelting electroslag ingots with set chemical components are obtained; the remelting electroslag ingot is subjected to cogging forging at the heating temperature of 1150-1250 DEG C, the deformation is controlled to range from 30% to 70%, and a flat blank is obtained; the flat blank is subjected to hot rolling at the heating temperature of 1150-1250 DEG C, the deformation is controlled to be 50%-90%, and a strip blank is obtained; and the strip blank is sequentially subjected to rough cold rolling, first surface coping, finish cold rolling, second surface coping and withdrawal and straightening, and the nickel-based alloy strip foil is obtained. The nickel-based alloy foil with the high-quality surface is obtained by reducing defect sources layer by layer through high-temperature large-deformation forge welding shrinkage, hot rolling recrystallization refining, cold rolling layering hardening depth control, SiC micro cutting defect removal, finish rolling mirror surface copying and annealing refining, micro crack removal through ultra-finishing and residual crack closing through tension withdrawal and straightening.

Method for friction stir welding or processing high strength steel

A method of processing high-strength steel includes providing a first piece of high-strength steel. Friction stir processing the first piece of high strength steel is performed by pre-heating an area in advance of a friction stir welding tool and moving the friction stir welding tool between 500 mm and 300 mm per minute to attain a mixed zone having a mixed zone temperature at the mixed zone between a eutectoid temperature and a forge welding temperature from a combination of the friction from the friction welding tool and the step of pre-heating.

Method for forming a forged and welded structure split gear rim

PendingCN122274597AGear wheelMachine
A method for forming a forged and welded split gear rim involves forging a full circular ring using a large ring rolling mill and cutting it into two semi-circular rings. Radial extrusion using hydraulic jacks and a square box prevents radius expansion after the full circle is cut, reducing the radius of the semi-circular rings to their pre-welding radius. A tie rod fixture then fixes the reduced-diameter, straightened semi-circular rings, allowing for heat treatment while maintaining the radius dimensions. Finally, removing the tie rod fixture and machining the components allows the two semi-circular rings to be welded into a full circular rim. This method eliminates the need for large plate rolling machines to bend steel plates into arc shapes and for extending the ends of the steel plate as clamps. Therefore, it reduces costs in terms of both equipment and materials used. This simplifies the production process, enabling manufacturers without large plate rolling machines or access to large quantities of high-strength steel plates to produce forged and welded split gear rims.
