Vacuum Welding Technical

We have vacuum brazing, vacuum diffusion welding and friction stir welding technologies, and are committed to supporting machining and manufacturing for special enterprises<

What is vacuum brazing?

Vacuum brazing refers to the use of filler metal (called solder or solder) whose melting point is lower than that of the base metal in a vacuum environment. At the temperature of the melting point of the brazing filler metal, the liquid brazing filler metal is used to wet and spread on the surface of the base metal and fill the gaps in the base metal, so as to dissolve and diffuse with the base metal, so as to realize the connection between parts.

This process welds parts with small deformation, especially suitable for mass production, and has important applications in aviation, aerospace, automobile, electronics and other fields. In addition, the characteristics of this process also determine that it is especially suitable for the welding of composite materials, ceramics, crystals and other special materials, and is an indispensable process in the forming and manufacturing of such materials.

What is vacuum diffusion welding?

Vacuum Diffusion Welding means that in a vacuum environment, the closely fitting components are kept under a certain temperature and pressure for a period of time, so that the atoms between the contact surfaces diffuse each other to form a connection Although diffusion welding is a welding process with a long history, it has not been developed rapidly until recent years. The weld seam of this process is invisible to the naked eye, and no brazing filler metal is added and no material is melted.

What is friction stir welding?

Friction stir welding is that the stirring head rotates at a high speed and rubs against the workpiece to be welded, generating heat to form a thermoplastic layer, the stirring head and the workpiece move relatively, and the thermoplastic metal continuously formed in front of the stirring head Transfer to the back of the mixing head, filling the cavity behind, thus forming the method of connection.

At the beginning of welding, the stirring head rotates at a high speed, and the special-shaped finger quickly drills into the welding seam of the plate to be welded. At this time, part of the metal is extruded from the surface, and the shoulder and the surface of the workpiece to be welded generate heat. The generation of the cavity is continuously carried out by filling, and the metal in the weld area undergoes extrusion, frictional heat generation, plastic deformation, transfer, diffusion,

Manufacturing of military chassis

As a safety-critical industry such as aerospace specialty, the welding process must define many performance criteria. For applications where tightness is critical, use our machining to meet all requirements and productivity. We are equipped with advanced CNC machining centers, as well as vacuum brazing, vacuum diffusion welding, and friction stir welding technologies.
