A method of welding by the heat produced by a laser beam. The high-intensity, concentrated heat allows the welding of exotic alloys that cannot be welded by other methods.
Industry:Aviation
A method of welding in which the flame is directed back over the finished weld, rather than ahead of the weld.
Industry:Aviation
A method of welding in which the metal is heated by an electric arc whose temperature has been greatly intensified by the injection of a gas. The plasma arc becomes a jet of high current density that produces temperatures of up to 60,000°F (33,316°C). One of the chief advantages of plasma arc welding is the concentration of this extreme heat which allows parts to be welded with a minimum of distortion.
Industry:Aviation
A method of welding in which the metal is melted by heat generated by alternating current induced into the metal.
Industry:Aviation
A method of welding in which the two ends of the metal to be joined are heated until they are almost, but not quite, melted. The ends are placed together and hammered until they flow together and become one piece.
Industry:Aviation
A method of welding metal by the heat produced when a high-speed stream of electrons strikes the metal. Electron-beam welding is used in applications in which the heat must be concentrated at the point the weld is being made.
Industry:Aviation
A method of welding thin material. Skip welding is done in a series of short beads, with a space between each bead about as long as one of the beads. After the first series of beads is made, a second series is made between each of the first ones.
Skip-welded material is less likely to warp than material welded with one continuous bead. Skip welding is sometimes called step welding.
Industry:Aviation
A method of welding thin sheets of metal by clamping them tightly together and passing electric current through them. The heat produced by the current melts the metal, and the pressure forces the molten metal from the two sheets together. Spot welding and seam welding are both types of electrical resistance welding.
Industry:Aviation
A method of winds-aloft observation by visually tracking a pilot balloon.
Industry:Aviation
A method of working sheet metal in which the metal is bent without heating it.
Some types of metal such as thin sheets of aluminum and magnesium alloys are normally bent cold, but other metals, especially thick sections of steel, are heated red-hot before they are bent.
