equipment modification. An alteration to machinery or equipment that changes the original design.
fracture toughness. The ability of a material to resist fracture when a flaw is present. It is typically measured by Charpy V-notch. dynamic tear. plane-strain fracture toughness. or drop-weight nil-ductility transition temperature tests.
fracture toughness variable (T). A qualification variable that is required when fracture toughness is specified by the Engineer. When fracture toughness is not required, these variables shall be considered data variables (formerly known as Supplementary Essential Variable).
Manufacturer. The organization responsible for the design and fabrication of the end product created utilizing this specification.
operator of automatic welding equipment. Welding personnel who operate equipment that requires only occasional or no observation and no manual adjustment of the controls.
Owner. The person, company, or agency purchasing the equipment.
procedure qualification variable. One of a set of elements that define the qualification limits of a Welding Procedure Specification (WPS).
performance qualification variable. One of a set of requirements that define the qualification limits of welders and welding operators.
qualified person. A person who, by possession of a recognized degree or certificate of professional standing, or who, by extensive knowledge, training, and experience, has successfully demonstrated the ability to solve or resolve problems relating to the subject matter and work.
qualification variable (0). See performance qualification variable and procedure qualification variable (formerly known as Essential Variable).
repair. The restoration of machinery or equipment to meet its intended performance without changing the original design. structural welds. Welds which carry the primary working loads during normal operations.
welding variable. Any controllable detail of a welding procedure which is required to be addressed on the Welding Procedure Specification (WPS)
4. Basic Weld Detail
4.1 Groove Welds
4.1.1 A complete joint penetration (CJP) weld is a groove weld in which weld metal extends through the entire joint thickness. The size of a CJP groove weld shall be the thickness of the thinner part joined.
4.1.2 A partial joint penetration (PJP) weld may be welded from one or both sides and has incomplete joint penetration. The size of a PJP groove weld shall be the joint penetration obtained. Welds in skecd I-Joints having dihedral y. angles less than 60° shall be designed as PJP groove welds (see 4.2.4).
4.1.3 The effective length for any groove weld, square or skewed, shall be the width of the part joined (see Figure 41).
4.1.4 The effective weld area shall be the effective weld length multiplied by the weld size.
4.2 Fillet Welds
4.2.1 The effective throat for a fillet weld shall be the minimum distance, minus any convexity, between the weld root and the face of a fillet weld (see Figures 4.2, 4.3, and 44). When approved by the Engineer, design values based on increased effective throat, as a result of increased joint penetration beyond the joint root, may be used. Welding shall be performed using a WPS qualified in accordance with 7.4.3 Fillet Weld Qualification for Deep Joint Penetration.
4.2.2 The length of a fillet weld shall be the overall length of the full-size fillet, including boxing.
4.2.3 The effective area shall be the effective weld length multiplied by the effective throat. Stress in a fillet weld shall be considered as applied to this effective area for any direction of applied load.AWS D14.3/D14.3M pdf download.
