Welding is a fabrication process that joins materials, usually metals or thermoplastics , by using high heat to melt the parts together and allowing them to cool, causing fusion. Welding is distinct from lower temperature metal-joining techniques such as brazing and soldering , which do not melt the base metal.

Used as a fuel gas in the oxyacetylene welding process. ALLOY: A mixture with metallic properties composed of two or more elements, of which at least one is a metal. AMMETER: An instrument for measuring electrical current in amperes by an indicator activated by the movement of a coil in a magnetic field or by the longitudinal expansion of a wire carrying the current. The term annealing usually implies relatively slow cooling.

Welding Terminology

BS provides terms, symbols and definitions for welding, brazing and thermal cutting of metals. Some definitions might also apply to non-metals. This standard is intended for designers, those drafting welding specifications, welding production, manufacturers and inspection personnel. Where it was felt that an existing definition needed clarification, this has been done while striving to not contradict the existing definition. As far as practicable, the numbering system used in this standard follows that of BS EN , with new numbers allocated to terms that are not in the European standard.

CTWEL - Welding Term and Definition

Welding is a fabrication process whereby two or more parts are fused together by means of heat, pressure or both forming a join as the parts cool. Welding is usually used on metals and thermoplastics but can also be used on wood. Some materials require the use of specific processes and techniques. A number are considered ' unweldable ,' a term not usually found in dictionaries but useful and descriptive in engineering. The material added to help form the join is called filler or consumable. The form of these materials may see them referred to as parent plate or pipe, filler wire, consumable electrode for arc welding , etc. Consumables are usually chosen to be similar in composition to the parent material, thus forming a homogenous weld, but there are occasions, such as when welding brittle cast irons, when a filler with a very different composition and, therefore, properties is used.

Acceptable Weld A weld that meets all requirements and acceptance criteria of the design and welding specifications. Actual Throat The shortest distance between the weld root and face. Alloy Metal having different properties than the original base elements. Arc Blow The deflection or wandering of an electric welding arc from its normal path due to magnetism in the base metal. Arc Welding A group of welding processes wherein coalescence or complete fusion is produced by heating with an electric arc.

Learn About Our Industrial Ovens. Become a Keen Distributor. The following are my non-technical definitions for some basic welding terms. These are good for the home hobbyist and those just coming into the welding field. Most people don't want to sit down and learn all the welding vocabulary and I don't blame 'em, I didn't either.


To become a skilled welder, you first need to learn the technical vocabulary (​language) of welding. The sections in this booklet introduce you to some of the basic.

Пуля ударила в асфальт в нескольких метрах позади. Беккер оглянулся. Убийца целился, высунувшись из окна. Беккер вильнул в сторону, и тут же боковое зеркало превратилось в осколки. Он почувствовал, как этот удар передался на руль, и плотнее прижался к мотоциклу. Боже всевышний.

 - Он пожал плечами. - Ладно, - нахмурилась Сьюзан.  - Попробуем еще… Кухня. - Спальня, - без колебаний отозвался .

Вот она показалась опять, с нелепо скрюченными конечностями. В девяноста футах внизу, распростертый на острых лопастях главного генератора, лежал Фил Чатрукьян. Тело его обгорело и почернело. Упав, он устроил замыкание основного электропитания шифровалки.
