Method for manufacturing thermometal metallurgy composite tube in pressure welding composite mode

Abstract

The invention provides a method for manufacturing a thermometal metallurgy composite tube in a pressure welding composite mode, and provides a manufacturing method for the metallurgy composite tube which is safe, reliable and high in interlayer bonding strength. According to the technical scheme, the method for manufacturing the thermometal metallurgy composite tube in the pressure welding composite mode includes the steps that an inner tube is coaxially mounted in an outer tube, inert gas is inflated to manufacture a tube blank after interlayer sealing is conducted on two ends of the tube, wherein a tapered flaring is formed in one end of the inner tube; the tube blank penetrates through an induction heating coil on an annular welding support and a welding core bar encircled by positive electrodes and mounted on a tail base, is fixedly connected with a pressure welding circular cone bearizing welding head at the position of the head portion of the welding core bar, and is clamped in a pneumatic chuck of a power head on a machine tool moving working table, the power head pulls the tube blank to rotate at a constant speed to the left, the positive electrodes are pressed down and are powered on, a V-shaped annular high-frequency current scanning heating zone or a resistance welding electrode pressing heating zone is formed on the tube blank interlayer surfaces between the positive electrodes and the negative electrode of the pressure welding circular cone bearizing welding head, metal on the bonding surface is fused, the tube blank is forced to pass through the axially fixed circular cone bearizing welding head, and the tube blank is welded into a whole.

AI Technical Summary

Benefits of technology

This patented technology improves upon existing methods for producing strong but expensive plastic composite pipings by combining specialized components together into a single unit without requiring complex processes like heat treatment. These new techniques improve productivity while reducing costs compared to traditional ways. They also provide better quality control over the final products due to their ability to maintain close surface connections during processing.

Problems solved by technology

Technologies described include current techniques for joining together multiple parts made from thin films (metalloys), including chemical vapor deposition processes like vacuum evaporation, sputtering, electroplating, laser weldability, and cold roll/hot pressurizing. These technological features contribute significantly improve the quality of these composites compared to traditional nonferritially fired cladded steels. Additionally, they provide technical advantages over conventional methods due to their ability to create both stable and durable connections without adding extra weight than usual ones.
