beryllium copper and resistance welding electrode

  • electrode

    welding electrodes. in arc welding, an electrode is used to conduct current through a workpiece to fuse two pieces together. depending upon the process, the electrode is either consumable, in the case of gas metal arc welding or shielded metal arc welding, or non-consumable, such as in gas tungsten arc welding. for a direct current system, the .

  • list of blade materials

    the blade of a knife can be made from a variety of materials, the most common being carbon steel, stainless steel, tool steel and alloy steel. other less-common materials used in knife blades include: cobalt and titanium alloys, ceramics, obsidian, and plastic . the hardness of steel is usually stated as a number on the rockwell c scale hrc .

  • electric resistance welding

    electric resistance welding is a welding process where metal parts in contact are permanently joined by heating them with an electric current, melting the metal at the joint. electric resistance welding is widely used, for example, in manufacture of steel pipe and in assembly of bodies for automobiles. the electric current can be supplied to electrodes that also apply clamping pressure, or may be induced by an external magnetic field. the electric resistance welding process can be further classi

  • tellurium copper

    tellurium copper is not suited to welding though can be welded with gas shielded arc welding or resistance welding; it can be readily soft soldered, silver soldered, or brazed. tellurium copper can be used as the electrode in electrical discharge machining edm .

  • electrogas welding

    electrogas welding egw is a continuous vertical position arc welding process developed in 1961, in which an arc is struck between a consumable electrode and the workpiece. a shielding gas is sometimes used, but pressure is not applied. a major difference between egw and its cousin electroslag welding is that the arc in egw is not extinguished, instead remains struck throughout the welding .

  • beryllium copper

    beryllium copper becu , also known as copper beryllium cube , beryllium bronze and spring copper, is a copper alloy with 0.5—3% beryllium and sometimes other elements. beryllium copper combines high strength with non-magnetic and non-sparking qualities. it has excellent metalworking, forming and machining properties. it has many specialized applications in tools for hazardous environments, musical instruments, precision measurement devices, bullets, and aerospace.

  • copper–tungsten

    copper tungsten is a good choice for a vacuum contact due to its low cost, resistance to arc erosion, good conductivity, and resistance to mechanical wear and contact welding. cuw is usually a contact for vacuum, oil, and gas systems.

  • list of welding processes

    this is a list of welding processes, separated into their respective categories.the associated n reference numbers second column are specified in iso 4063 in the european union published as en iso 4063 . numbers in parentheses are obsolete and were removed from the current 1998 version of iso 4063. the aws reference codes of the american welding society are commonly used in north america.

  • spot welding

    spot welding is a type of electric resistance welding used to weld various sheet metal products, through a process in which contacting metal surface points are joined by the heat obtained from resistance to electric current. the process uses two shaped copper alloy electrodes to concentrate welding current into a small 'spot' and to simultaneously clamp the sheets together. work-pieces are held together under pressure exerted by electrodes. typically the sheets are in the 0.5 to 3 mm thickness r

  • glidcop

    the hardness is comparable to many copper-beryllium and copper-tungsten alloys, while the electrical conductivity is comparable to rwma class 2 alloy. other additives for specialized applications include molybdenum, tungsten, kovar, and alloy 42. t 500 c 932 f glidcop al-15 has a yield strength of over 29 ksi 200 mpa .

  • berylliosis

    berylliosis, or chronic beryllium disease cbd , is a chronic allergic-type lung response and chronic lung disease caused by exposure to beryllium and its compounds, a form of beryllium is distinct from acute beryllium poisoning, which became rare following occupational exposure limits established around 1950. berylliosis is an occupational lung disease.
