Explosive Cladding Process

The explosive cladding process provides several advantages over other metal-bonding processes ... [Pg.143]

In 1962, the first method for welding (qv) metals ia spots along a linear path by explosive detonation was patented (8). This method is not, however, used iadustriaHy. In 1963, a theory that explained how and why cladding occurs was pubHshed (9). Research efforts resulted ia process patents which standardized iadustrial explosion cladding. Several of the patents describe the use of variables iavolved ia parallel cladding which is the most popular form of explosion cladding (10—13). Several excellent reviews on metal cladding have been pubHshed (14—16). [Pg.143]

Vessel heads can be made from explosion-bonded clads, either by conventional cold- or by hot-forming techniques. The latter involves thermal exposure and is equivalent in effect to a heat treatment. The backing metal properties, bond continuity, and bond strength are guaranteed to the same specifications as the composite from which the head is formed. AppHcations such as chemical-process vessels and transition joints represent approximately 90% of the industrial use of explosion cladding. [Pg.150]

Chemical-Process Vessels. Explosion-bonded products are used in the manufacture of process equipment for the chemical, petrochemical, and petroleum industries where the corrosion resistance of an expensive metal is combined with the strength and economy of another metal. AppHcations include explosion cladding of titanium tubesheet to Monel, hot fabrication of an explosion clad to form an elbow for pipes in nuclear power plants, and explosion cladding titanium and steel for use in a vessel intended for terephthaHc acid manufacture. [Pg.150]

Some of the restrictions on the use of aluminum are caused by manufacturing and fabrication problems and by its low mechanical strength. However, aluminum is widely used and is competitive with Type 316 stainless steel in many instances. The explosion-bonding process has made the aluminum cladding of steel practical, and... [Pg.265]

Important applications for titanium have been developed in processes involving acetic acid, malic acid, amines, urea, terephthalic acid, vinyl acetate, and ethylene dichloride. Some of these represent large scale use of the material in the form of pipework, heat exchangers, pumps, valves, and vessels of solid, loose lined, or explosion clad construction. In many of these the requirement for titanium is because of corrosion problems arising from the organic chemicals in the process, the use of seawater or polluted cooling waters, or from complex aggressive catalysts in the reaction. [Pg.875]

Detaclod Process or Explosive Cladding. (Explosive Bonding). This process developed in US ca I960 consists of bonding dissimilar metals into "clad plates by using precisely controlled detonation of large quantities of explosives. Clads are essentially structures... [Pg.518]

Like roll-clad products, explosively clad metals can be further processed by all fabrication procedures, although special welding conditions may be required. The problems of heat-treating systems of this kind are exemplified by the properties listed in Table 20.7 for a combination of fine-grained structural steel and titanium. [Pg.616]

Detaclad process or explosive cladding, which is also called explosive bonding, was developed by the DuPont Company. [Pg.30]

Plutonium-239 and tritium for use as military explosives are the two major transmutation products. The nuclear process for Pu-239 production is the same as for energy generation, but there are some differences (a) metallic natural uranium clad with aluminum facilitates later dissolution for plutonium recovery, and the reactor operates at a relatively low temperature because of the aluminum clad and better heat transfer (due to the metallic natural uranium) (b) the irradiation cycle is limited to a few months to minimize the Pu-239 conversion to Pu-240 and Pu-241 and (c) a carbon or a heavy water moderator is used to increase the neutron efficiency. [Pg.955]
