Tungsten Copper Alloy Connector
1. Description Of Tungsten Copper Alloy Connector:
Tungsten-copper connectors are mostly found in pipes, which connect the most vulnerable parts of the pipe by nesting or welding to improve performance. In addition, there are many forms such as tungsten copper rivets, tungsten copper bolts, tungsten copper electrodes, pins and so on.
2. Size and Performance Of Tungsten Copper Alloy Connector:
Tungsten Copper Alloy connector process as per customer's drawing.

3. Principle Of Tungsten Copper Alloy Connector:
1). Shape locking: It is the mutual clamping effect formed by the shape of the connected parts or the additional connecting parts, and the force that hinders the relative movement between the connected parts is generated on the joint surface;
2). Friction locking: two or more connected parts are pressed together, and positive pressure is generated on the joint surface. When there is a relative movement trend between the connected parts, the relative movement between the connected parts is blocked on the joint surface. friction force or friction torque;
3). Material locking: use the molecular bonding force between the material and the connected parts to connect them, such as welding and gluing.
4.Classification Of Tungsten Copper Alloy Connector:
Tungsten copper alloy connectors can be divided into three classification:
1). Rivets: refers to a short cylindrical rod with a semi-circular nail head at one end, insert it into each steel plate or steel nail hole to be connected, and press or hammer the protruding end into a second nail head , which can be divided into four types: semi-round head, high head, submerged head, and semi-submerged head;
2). Bolts: usually cylindrical rods with square or hexagonal heads at one end and threads at the other end, equipped with nuts and washers, which can fasten steel components or steel-wood components together, which can be divided into rough and Two kinds of refined bolts;
3). Welding rods: rod-shaped metal strips that are melted and filled at the junction of welding parts during welding. It is coated with anti-oxidation (alloying, etc.) flux. According to the mechanical properties and chemical composition of the metal material to be welded, as well as the requirements for the welding seam and the process conditions of the equipment, different types and types of electrodes are selected.
