What is Welding? - Definition, Processes and Types of Welds

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. Multi-user access to over 3, medical device standards, regulations, expert commentaries and other documents.

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. But if you will learn these, you'll be a cut above most beginners.

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.

Basic Welding Terms

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. In addition to melting the base metal, a filler material is typically added to the joint to form a pool of molten material the weld pool that cools to form a joint that, based on weld configuration butt, full penetration, fillet, etc. Pressure may also be used in conjunction with heat or by itself to produce a weld. Welding also requires a form of shield to protect the filler metals or melted metals from being contaminated or oxidized.

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.
