Century Dictionary and Cyclopedia
    • n weld The dyer's-weed, Reseda luteola, a scentless species of mignonette, native in southern Europe and naturalized further north. It was formerly much cultivated as a dye-plant, its pods affording a permanent yellow suited to both animal and vegetable fibers, later displaced, however, by quercitron, flavin, and the aniline dyes. Its seeds yield a drying-oil. Also yellow-weed, and sometimes woad or wild woad.
    • weld To unite or consolidate, as pieces of metal or a metallic powder, by hammering or compression with or without previous softening by heat. Welding is and has long been a matter of great practical importance, chiefly in the manufacture of iron and steel, and of the various tools, utensils, and implements made of those metals. Iron has the valuable property of continuing in a kind of pasty condition through quite a wide range of temperature below its melting-point, and this is a circumstance highly favorable to the process of welding. Most metals, however, pass quickly, when sufficiently heated, from a solid to a liquid condition, and with such welding is more difficult. The term welding is more generally used when the junction of the pieces is effected without the actual fusing-point of the metal having been reached. Sheets of lead have sometimes been united together by fusing the metal with a blowpipe along the two edges in contact with each other, and this has been called autogenous soldering, or burning if the heating was done with a hot iron. Still, “the difference between welding and autogenous soldering is only one of degree” (Percy). The term welding is also used in speaking of the uniting of articles not metallic. Most metals when in the form of powder can be consolidated or welded into a perfectly homogeneous mass by sufficient pressure, without the aid of heat. The same is true of various non-metallic substances, such as graphite, coal, and probably many others. A method of welding has been recently invented by Elihu Thomson, which appears to be capable of being employed with a variety of metals on a very extensive scale. In this, which is known as electric welding, a current of electricity heats the abutting ends of the two objects which are to be welded, these being pressed together by mechanical force, and so arranged with reference to the electric current that there is a great and rapid accumulation of heat at the joint, in consequence of the greater relative conductivity of the rest of the circuit. This method of welding in some cases partakes of the nature of autogenous soldering, the pieces of metal being actually fused while uniting; in other cases, as with iron, nickel, or platinum, the union may take place without fusion, as in ordinary welding. In electric welding the pressure which forces the metallic surfaces together may, in the case of a plastic metal like iron, be either quiet or percussive in character; in autogenous soldering a more delicate and quiet Pressure is generally preferred. In case of large articles hydraulic pressure can be used to force their surfaces into contact with each other.
    • weld Figuratively, to bring into intimate union; make a close joining of: as, to weld together the parts of an argument.
    • weld To undergo the welding process; be capable of being welded.
    • n weld A solid union of metallic pieces formed by welding; a welded junction or joint.
    • weld A Middle English form of wield.
