API 1104 - ANSWER The API standard, Welding of Pipelines and Related Facilities. This
standard is often used in construction of cross country pipelines
ASME - ANSWER American Society of Mechanical Engineers
ASNT - ANSWER American Society of Nondestructive Testing
AWS - ANSWER American Welding Society. Has 9 codes and many standards.
AWS A3.0 - ANSWER The AWS Standard Welding Terms and Definitions
AWS B1.10 - ANSWER The AWS guide for the Nondestructive Examination of welds
AWS B1.11 - ANSWER The AWS guide for the Visual Examination of Welds
AWS B5.11 - ANSWER The AWS specification for the Qualification of Radiographic Inter-
preters
AWS D1.1 - ANSWER The AWS Structural Welding Code-Steel.
AWS D1.5 - ANSWER The AWS Bride Welding Code used in the U.S. for the construction
of bridges

,AWS D15.1 - ANSWER The AWS Railroad Welding Specification-Cars and Locomotives.
This specification covers welding of railroad cars and locomotives.
CAWI - ANSWER Certified Associate Welding Inspector
CWI - ANSWER Certified Welding Inspector
KASH - ANSWER An acronym for Knowledge, Attitude, Skills and Habits. The basic tools of
a welding inspector.
NDE - ANSWER Nondestructive examination.
NDI - ANSWER Nondestructive Inspection
NDT - ANSWER Nondestructive Testing
QC1 - ANSWER The AWS Standard for AWS Certification of Welding Inspectors. Defines
the requirements and program for the AWS to certify welding inspectors.
SCWI - ANSWER Senior Certified Welding Inspector
SNT-TC-1A - ANSWER The ASNT Recommended Practice, Personnel Qualification and Cer-
tification in Nondestructive Testing, outlines the certification program for NDT technicians.
Actual Throat - ANSWER The shortest distance between the weld root and the face of a
fillet weld
Back Weld - ANSWER A weld made at the back of a single groove welded joint after the
completion of the groove weld.
2
,Backing - ANSWER A material or device placed against the back side of the joint or at
both sides of a weld in ESW and electrogas welding, to support and retain molten weld
metal. The material may be partially fused or remain infused during welding and may be ei-
ther metal or nonmetal.
Backing Weld - ANSWER Backing in the form of a weld, made before the primary weld.
Backstep Sequence - ANSWER A longitudinal sequence in which weld passes are made in
the direction opposite to the progression of welding.
Bevel - ANSWER An angular edge shape.
Bevel Angle - ANSWER The angle between the bevel of a joint member and a plane per-
pendicular to the surface of the member. This dimension equals one half of the groove or
included angle when the edges of both members are prepared at the same angle. When
only one member is prepared at an angle, this dimension is still indicated in the same posi-
tion on the welding symbol for groove angle, but equals the total degree of preparation of
the groove.
Bevel Groove Weld - ANSWER A type of groove weld in which the mating members of the
joint have one single-bevel or double-bevel edge and one square edge preparation.
Block Sequence - ANSWER A combined longitudinal and cross sectional sequence for a
continuous multiple pass weld in which separated increments are completely or partially
welded before intervening increments are welded.
Boxing - ANSWER The continuation of a fillet weld around a corner of a member as an ex-
tension of the principle weld
3
, Buildup - ANSWER A surfacing variation in which surfacing material is deposited to
achieve the required dimensions.
Butt Joint - ANSWER A joint between 2 members aligned approximately in the same
plane.
Buttering - ANSWER A surfacing variation that deposits surfacing metal on one or more
surfaces to provide metallurgically compatible weld metal for the subsequent completion of
the weld.
Butting Member - ANSWER A joint member that is prevented, by the other member,
from movement in one direction perpendicular to its thickness dimension. For example,
both members of a butt joint, or one member or a T-joint or corner joint.
Cascade Sequence - ANSWER A combined longitudinal and cross sectional sequence in
which weld passes are made in overlapping layers.
Chain Intermittent Fillet Weld - ANSWER An intermittent weld on both sides of a joint in
which the weld increments on one side are approximately opposite those on the other side.
Cladding - ANSWER A surfacing variation that deposits or applies surfacing material usu-
ally to improve corrosion or heat resistance.
Complete Joint Penetration - ANSWER A joint root condition in a groove weld in which
weld metal extends completely through the joint thickness.
Concave Fillet Weld - ANSWER A fillet weld having a concave face.
Concavity - ANSWER The maximum distance from the face of a concave fillet weld per-
pendicular to a line joining the weld toes
