3. Definitions
Terms used in this specification shall be in accordance with AWS A3.0. Standard Welding Terms and Definitions. Additional terms specific to this standard are defined in this section.
consumables. Filler metals, fluxes, and shielding gases used in the welding process.
effective weld areas
groove welds. The effective area is the effective weld length multiplied by the weld size. (See 4.2 for additional details.)
fillet welds. The effective area is the effective weld length multiplied by the effective throat. (See 4.3 for additional details.)
plug and slot welds. The effective area shall he the nominal area of the hole or slot in the plane of the faying surface.
Engineer. The responsible technical authority.
essential variable. A welding parameter whose change beyond the tolerances permitted by a standard requires requalification of a welding procedure, welder, or welding operator.
Manufacturer. The organization responsible for the performance of the work covered by this specification.
modification. An alteration to machinery or equipment that changes the original design.
Owner. The person, company, or agency that purchases the equipment.
piping porosity. A form of porosity having a length greater than its width that lies approximately perpendicular to the weld face. When the porosity extends to the weld surface, it is frequently referred to as “pin holes.”AWS D14.3 pdf download.
