Products Description
Copper Tungsten Insert Welding Electrode are mainly composed of two parts: the electrode body and the electrode surface. The electrode body is generally made of copper alloy material, and the electrode surface is made of refractory metal, such as tungsten or molybdenum.Such a combined electrode can prolong the service life of the electrode, because copper with high thermal conductivity and high electrical conductivity undertakes a good heat dissipation function, and the metal tungsten surface with a high melting point can reduce arcing and high temperature corrosion.Moreover, they can maximize the concentration of thermal energy on the workpiece to be welded, thereby forming an effective nugget, which can reduce costs and improve production efficiency.Copper tungsten-faced welding electrodes have gone through vacuum casting, hot and cold forging, solution processing and hot processing,forming a high-quality welding electrode with dense internal structure and high smoothness.
Features Of Copper Tungsten Insert Welding Electrode
1. High hardness and wear resistance: The hardness of tungsten insert (HRC ≥ 60) is combined with the toughness of copper matrix, suitable for welding of high hardness materials.
2. High temperature resistance and arc ablation resistance: The melting point of the tungsten matrix (3410°C) is combined with the conductivity of the copper phase, and can withstand high current and arc impact.
3. Zero gap and zero resistance combination: The bonding of copper and tungsten adopts a special process to achieve zero gap and zero resistance to ensure conductive performance.
4. High precision and long life: High processing accuracy, longer life than traditional electrodes, reducing downtime and maintenance time.
Application of Copper Tungsten Insert Welding Electrode
Copper Tungsten Insert Welding Electrode are widely used in precision welding processes in the electronic field, such as the welding of chip transformer leads, the welding of earphone leads, the welding of earphone leads, the welding of induction IC card coils and the welding of high-frequency communication components.They are also often suitable for welding copper products such as copper wire, copper lug, copper foil and copper cross wire. When manufacturing and welding superhard alloys,copper tungsten-faced welding electrodes show ultra-high high temperature strength and stiffness, excellent arc resistance and wear resistance, strong anti-blocking resistance and high welding accuracy.
