Soldering Wolfram Wires

Wolfram wires: Fine wire made by forging and drawing tungsten bars. Wolfram wiresis mainly used in electric light sources such as incandescent lamps and halogen tungsten lamps. Wolfram wires used as various luminescent materials in light bulbs also require the addition of a small amount of potassium, silicon, and aluminum oxides during the smelting process. Wolfram wires are generally drawn using various drawing dies. It is mainly used for manufacturing filament and high-speed cutting alloy steel, as well as optical instrument, chemical instruments and other functions. Wolfram wires has a high melting point, high resistivity, good strength, and low vapor pressure, making it the best material for making incandescent filaments among all pure metals. But wolfram wires has a high hardness and brittleness, making it difficult to process. When the current is heated to a certain temperature through the wolfram wires, the resistance value of the wolfram wires also increases to a certain value (generally, the resistance value of the metal wire increases with the increase of temperature).

The tip of ultrasonic soldering iron vibrates at ultrasonic frequencies. This vibration induces cavitation in the molten solder, which breaks up and removes oxides and promotes wetting. Ultrasonic soldering iron enables the easier joining of hard-to-solder materials which are known as impossible or difficult to be soldered in conventional soldering. Eco-friendly soldering is achieved by fluxless soldering and no post treatment to remove flux. The ultrasonic soldering technology is widely used in wolfram wires. The ultrasonic soldering iron of Cheersonic produces high quality soldered joints. Using the solder alloy, can easily solder directly to glass, ceramics and other low solderability materials.
