Tungsten Worm Weights 1

Details: Category: Tungsten Information; Published on Wednesday, 24 September 2014 08:58; Written by Sherry; Hits: 532

Tungsten worm weights, also called tungsten barrel weights in some countries, are known as "Diamond Series" because of they are drilled, beveled and diamond polished to avoid damaging the line.

Tungsten worm weights are feature for cone or bullet shape, which designed to easily slip through weeds and appreciated by bass anglers. The weights have a hole through their center to hold the fishing line. Rigged directly in front of soft-plastic baits such as worms or craws, worm weights can be fixed in place or allowed to slide along the line.

Tungsten worm weights are equipped with nylon inserts to keep your line in top working order and not nicked by the weight edge as is common with other weights.

Tungsten rod is a very hard, dense metal that has the highest melting temperature of all metals: 6,192°F (3,422°C). It is a chemical element; atomic number 74. Tungsten has excellent corrosion resistance and is only slightly affected by acids. Tungsten Rod is manufactured by powder-metallurgical manufacturing techniques. Moreover, It characterized by high temperature resistance and high creep resistance.

Specifications of tungsten rod:

type	purity of tungsten	application
WAL1	>=99.92%	filament,cathode and components for electron tubes,electrode for the gas discharge tube.etc.
WAL2	>=99.92%
WAL3	>=99.92%	grid siderod,lead,support,electrode for the discharge lamp,etc.

Tungsten Rods for Electrode

Details: Category: Tungsten Information; Published on Tuesday, 23 September 2014 15:31; Written by jwy; Hits: 528

Tungsten rod for electrode shared the same properties of tungsten, tungsten rod is frequently used as electrodes in high-energy electrical equipment (such as targets in X-ray tubes and spark gaps in Tesla Coils) where other metals would vaporize or melt. The thin filaments in light bulbs are made of fine Tungsten wire. Our solid Tungsten rod are 1/8" in diameter, and 3" to 3.5" long.

Selecting the right tungsten is crucial to a successful TIG weld. You have to insure the correct tungsten is used for the type of metal you are welding, the type of technology used in your welder such as transformer or inverter, and the thickness of the metal you will need to weld. This leaves you with a variety sizes ranging from 1/16 to 1/8” and the types of tungsten’s such as the Pure Tungsten (TP), 2% Thoriated Tungsten (TT2), 2% Ceriated Tungsten (TC2), and 2% Lanthanated Tungsten (TL2). Fortunately, LONGEVITY offers high quality tungsten electrodes and explains which tungsten is required for the right application. Pure Tungsten (TP) – (green tipped) - Pure tungsten readily forms a ball on the end. It is designed for use with transformer-based power sources for AC welding of aluminum. Unfortunately, LONGEVITY does not carry transformer based technology considering the size and weight of TRANSFORMER welders. Therefore, this tungsten is rarely sold buy our sales staff.

Tungsten inert gas (TIG) welding, also known as gas tungsten arc welding (GTAW), is an arc welding process that uses a tungsten electrode to transmit the electric arc to the work piece. Unlike other arc welding methods, the tungsten electrode does not provide material to the weld, so a separate filler rod is needed for that purpose. Some tungsten electrodes are made with a small amount of thorium, which is a radioactive material and improves the welding qualities of the electrode.

Welding with tungsten: Tungsten has the highest melting point of all metals, so the electrode material does not melt when exposed to the high temperatures of the arc. Tungsten can be used to weld metals and specific alloys designed to have a high melting point. Even though the tungsten electrode doesn't melt during the welding process, the electrode can wear or chip over time. The electrode can be reshaped to a conical or rounded shape using a grinder.

Electrodes that contain thorium: Thoriated tungsten electrodes are made from tungsten combined with 1 to 2 percent thorium in the form of thorium dioxide. Thoriated tungsten electrodes result in improved welding properties over pure tungsten electrodes. By using thoriated tungsten electrodes, welders find it easier to start the arc and maintain the arc, reduce weld contamination, carry a higher level of current, and achieve a longer electrode life through reduction in wear.
