Description
Technical Field
The invention relates to the technical field of welding equipment, in particular to a welding device for heterogeneous workpieces.
Background
Friction welding refers to the process that a welding tool rotating at a high speed is used for locally melting a welded material by heat generated by friction between the welding tool and a workpiece, when the welding tool moves forwards along a welding interface, the plasticized material flows from the front part to the rear part of the welding tool under the action of the rotating friction force of the welding tool, and a compact solid-phase welding seam is formed under the extrusion of the welding tool. Compared with the traditional fusion welding, the friction welding has the advantages of low heat input, high efficiency and energy saving, and is particularly suitable for welding dissimilar metals.
In friction welding, friction pressure and welding pressure are two important parameters. The friction pressure refers to the pressure to which the workpiece is locally subjected on both sides of the weld head. By applying friction pressure, workpieces on two sides of the welding head can be tightly attached, the contact area of welding is increased, and the welding quality is improved. Welding pressure refers to the force exerted on a workpiece during friction welding. The welding pressure is used for stably fixing the workpiece on the welding head and keeping the deformation of the workpiece so as to avoid welding defects. The magnitude of the friction pressure and the welding pressure can affect the quality and effectiveness of the friction weld. Proper friction pressure and welding pressure can ensure that workpieces at two sides of a welding head are tightly attached, and the welding quality is high; if the pressure is too small, the workpiece may not be completely sealed, and the welding quality is poor; if the pressure is too high, the workpiece may be severely deformed, thereby affecting the welding quality. Therefore, when performing the friction welding operation, it is necessary to reasonably set the friction pressure and the welding pressure according to the material and the welding requirements to achieve a good welding effect.
