Tungsten alloy swaging rod is made of tungsten alloy rod through calcinations. The normal method used in the processing are extruding, forging and sintering. After calcinations, tungsten alloy swaging rod has higher ductility, toughness and tensile strength than tungsten alloy rod, so it can be used for a longer time. Warhead of FGM-148 is made of tungsten alloy swaging rod.

FGM-148 is a United States-made man-portable fire-and-forget anti-tank missile fielded to replace the Dragon antitank missile in US service.

FGM-148  is a fire-and-forget missile with lock-on before launch and automatic self-guidance. The system takes a top-attack flight profile against armored vehicles (attacking the top armor, which is generally thinner), but can also take a direct-attack mode for use against buildings. This missile also has the ability to engage helicopters in the direct attack mode. It can reach a peak altitude of 150 m (500 ft) in top-attack mode and 60 m in direct-fire mode. It is equipped with an imaging infrared seeker. The tandem warhead is fitted with two shaped charges: a precursor warhead to detonate any explosive reactive armor and a primary warhead to penetrate base armor.

With the high density and high hardness of tungsten alloy swaging rod, FGM-148 can penetrate the armor on the top of tank and destroy the tank.

When you are going to buck rivets, this is just another name for setting them in place. A rivet is essentially a metal pin with a head on one end and a shank that goes through a hole between two pieces of metal. When the head is compressed against a bucking bar on the shank side, the shank has no where to go and expands outward forming another head. These two heads on either side act as a fastener and hold the piece of metal tightly together.

1.Place the rivet to be bucked into a rivet hole.

2.Push the pneumatic hammer against the head of the rivet, while at the same time placing the bucking bar on the shank of the rivet.

3.Find the center of the shank with the bucking bar. This does not have to be an exact science, but the closer the center can be found while pushing against the shank, the more symmetrical the expansion of the rivet shank will be.

4.Hold the bucking bar steady against the shank once the center has been found, then activate the pneumatic hammer to drive the rivet home.

 The bucking bar includes a housing and a driven member movable with respect to the housing. The worker using the bar holds it with the driven member pressed against one end of the rivet. When blows are delivered from the hammer through the rivet to the bar, an appropriate reaction force is generated automatically by mechanisms within the bar. These mechanisms include at least a first pressure chamber and an exhaust port for releasing pressure from the pressure chamber to the atmosphere. By controlling the flow of air through the pressure chamber, the mechanisms within the bucking bar control the forces acting on the driven member during the recoil and rebound motions. Preferred control mechanisms include a second pressure chamber and a movable shuttle. The shuttle is initially biased in a preferred direction by a biasing element in the form of a coil spring. Subsequent movement of the shuttle is dependent upon the characteristics of the hammer blow. Generation of reaction force within the bucking bar is in turn dependent on the position and motion of the shuttle. Preferably, the shuttle acts as part of several valves controlling the flow of pressurized air into and out of the two pressure chambers. A piston fixed to the end of the driven member acts as part of another valve for controlling the flow of pressurized air into the first pressure chamber.

Bucking bars are tools used to form bucktails (the head formed during riveting operations) on rivets.They come in many different shapes and sizes, asshown in figure 13-4.Bucking bars are normally made from an alloy steel similar to tool steel. Theparticular shape to be used depends upon the locationand accessibility of the rivet to be driven. The sizend weight of the bar depend on the size and alloy ofthe rivet to be driven. Under certain circumstances,and for specific rivet installations, specially designedbucking bars are manufactured locally. These barsare normally made from tool steel. The portion of the bar designed to come in contact with the rivet has apolished finish.This helps to prevent marring offormed bucktails. Bucking-bar faces must be keptsmooth and perfectly flat and the edges and cornersrounded.

NOTE: Never hold a bucking bar in a viseunless the vise jaws are equipped with protective covers to prevent marring of thebucking bar.A satisfactory rivet installation depends largelyon the condition of the bucking bar and your ability touse it.If possible, hold the bucking bar in such amanner that will allow the longest portion of the bar tobe in line with the rivet. You should hold the buckingbar lightly but firmly against the end of the rivet shankso as not to unseat the rivet head. The inertia of thistool provides the force that bucks (upsets) the rivetand forms a flat, headlike bucktail.

IDAS (based on the IRIS-T air-to-air missile) is primarily targeted against air threats, such as ASW helicopters, but also against small or medium-sized surface vessels or coastal land targets. It is currently being developed by Diehl BGT Defence and HDW, which is a part of Thyssen-Krupp Marine Systems (TKMS), to be fired from Type 212's torpedo tubes. IDAS will be fibre-optic guided and officially has a range of approx. 20 km. Four missiles will fit in one torpedo tube, stored in a magazine. First deliveries of IDAS for the German Navy and operational service are planned from 2014 on.

The IDAS system is also the world's first missile which gives submarines the capability to engage air threats whilst submerged, and the first tube-launched missile that does not emerge in a capsule, but is fired directly from the torpedo tubes.

With the high density and hardness of military tungsten alloy swaging rod, IDAS can penetrate armor and destroy helicopter.

The Tomahawk is a long-range, all-weather, subsonic cruise missile. The missile was named after the Native American axe. Introduced by General Dynamics in the 1970s, it was initially designed as a medium to long-range, low-altitude missile that could be launched from a surface platform. It has been improved several times and, due to corporate divestitures and acquisitions, is now made by Raytheon. Some Tomahawks were also manufactured by McDonnell Douglas (now Boeing Defense, Space & Security).

The Tomahawk missile family consists of a number of subsonic, jet engine-powered missiles designed to attack a variety of surface targets. Although a number of launch platforms have been deployed or envisaged, only sea (both surface ship and submarine) launched variants are currently in service. Tomahawk has a modular design, allowing a wide variety of warhead, guidance, and range capabilities.

With the high density and hardness of military tungsten alloy swaging rod, Tomahawk can penetrate armor and destroy warship.

Thorium tungsten electrode characteristics

Thorium oxide containing tungsten thorium ( thorium dioxide or thoria ) , in the United States it is most commonly used tungsten electrodes , determine other tungsten electrodes have become a standard of good or bad . However, since this has a low level of tungsten electrodes radiological hazards , many users have switched to other options. In general , a 2% thoriated tungsten electrode is a relatively good tungsten electrode having the lowest work function , even when the overload voltages also performed well . Thorium tungsten electrode performance in many respects superior to pure tungsten electrodes . Than pure tungsten thorium oxide provides about 20 percent higher than the current carrying capacity , generally longer life , but also help prevent contamination when welding . Using thoriated tungsten electrode , arc easier than that of pure tungsten electrode and the arc or zirconium tungsten electrodes more stable. Thorium tungsten electrode 1% (EWTh - 1) and thorium tungsten electrode 2% (EWTh - 2) can be used for DCEN. They remain in the welding process sharpened tip , which can be used to weld steel pipe , not usually direct current, because it is difficult to maintain a spherical tip welding without cracking , which is a must for direct current .

Thorium tungsten electrode application

Thoriated tungsten electrodes are usually used for the DC negative electrode or carbon, stainless steel, nickel alloys, titanium alloys and other applications of the positive electrode . Their operating performance , even when the overload current of the operation can be very good .

Thoriated tungsten electrode is usually used in the field of carbon and stainless steel . Thorium oxide content of 2% thoriated tungsten electrode is typically less than 1% of the thorium content of the tungsten electrode to better improve performance . Communicate using thorium tungsten electrode welding, faster , and to be used with caution in order before welding on AC DC welding reaction . In AC welding, balled balls will not melt, so the effect is not as liquid ball so well.

Thoriated tungsten electrodes are usually used for DC welding field, while pure tungsten electrodes for AC welding . During the welding process , the staff should carefully read the instructions for use of thorium tungsten electrode .
