The double top forging butt welding machine adopts a composite process of forging and welding. Through the double top forging force, the two metal workpieces to be welded are brought into contact and fused at high temperature, thereby achieving high-quality welding connection. Its main advantage is that it can effectively improve the welding quality, reduce thermal cracks and welding defects, and is particularly suitable for some high-strength or difficult-to-weld materials that are difficult to connect by traditional welding methods. The working principle of the double top forging butt welding machine is based on a composite process combining forging and welding. Before welding, the double top forging butt welding machine preheats the workpiece to be welded through a heating device to make the surface of the workpiece reach a suitable temperature range. This process is to ensure that the metal can be fully softened after heating, which is conducive to subsequent welding and forging. Then, the double top forging butt welding machine will apply forging force at both ends of the workpiece. This process makes the metal surface contact more closely and promotes the diffusion between the metals. The forging pressure causes the metal to produce plastic deformation at high temperature, thereby accelerating the formation of the welded joint. The current passes through the electrode to heat the welding area of the workpiece, so that the contact surface reaches the appropriate temperature, ensuring the fluidity and welding strength of the metal during the welding process. The combination of current action and forging force can effectively eliminate the oxide layer on the metal surface and improve the contact quality of the metal.
