Welding Terms Flashcards
Cascade Sequence
A combined longitudinal and cross-sectional sequence in which weld passes are made in overlapping layers.
Block Sequence
A combined longitudinal and cross-sectional sequence for a continuos multiple pass weld in which separated increments are completely or partially welded before interring increments are welded.
Fillet Weld
A weld of approxament triangular cross section joining two surfaces approxament at right angles to eachother in a lap joint.
The leg lenghts of the largest isosceles (Two legs of equal length) right triangles which can be inscribed with in the fillet weld cross section.
Back Sequence
A longitudinal sequence in which weld passes are made in the direction opposite to the progess of welding.
Heat Affected Zone
(HAZ)
The portion of the base metal whose mechanical properties or microstructure have been altered by heat of welding, brazing, soldering or thermal cutting.
Joint Penetration
The distance the weld metal extends from the weld face into a joint.
Root penetration
The distance that the weld metal extends into the joint root.
Weld Throat
Generally the shortest distance throught the cross section of the weld.
Root Reinforcement
Weld reinforcement opposite the side from which welding was done.
Face Reinforcement
(Weld Crown)
Weld reinforcement on the side of the joint from which welding was done.
Root Surface
The exposed surface of the weld opposite the side from wich welding was done.
Weld Face
The exposed surface of a weld face and the base metal.
Spot Weld
Plug Weld
A weld made in a circular hole in one member of a joint fusing that memeber to another member.
Slot Weld
A weld made in an elongated hole in one member of a joint fusing that member to another member.
Backing Weld
Backing in the form of a weld.
Back Weld
A weld made at the back of a single groove weld.
Surfacing Weld
A weld applied to a surface, as opposed to making a joint to obtain desired properties or dimensions.
Seam Weld
A continuous weld made between or upon overlapping members.
Faying Weld
The matting surface of a member that is in contact with or in close proximity to another member to which it is joined.
Edge Weld
A weld in an edge joint.
Groove Radius
(J or U Grooves)
The radius used to form the shape of a J or U Groove.
Groove Angle
The total included Angle of the Groove between work pieces.
Bevel Angle
The angle between the bevel of a joint member and a plane perpendicular to the surface of the member.
Bevel
(Chamfer)
An angular edge slope.
Root Opening
(Gap)
A seperation between the work pieces at the root.
Root Edge
A root face of zero width.
Rootface
(Landing, Nose, Flat)
That portion of the groove face adjacent to the joint.
Groove Face
That surface of a member included in the Groove
Joint Root
That protion of a joint to be welded where the member aproach closest to eachother.
Theoretical Throat
The distance from the begining of the joint root perpendicular to the hypotenuse of the Largest right triangle that can be inscribed within the cross section of a fillet weld. The dimension is based on the assumption that the root opening is equal to zero.
Effective Throat
The minimum distance minus any convexity between the weld root and the face of a fillet weld.
Actual Throat
The shortest distance between the weld root and the face of the weld.
Single Welded Joint
A joint that is welded from one side only.
Double-Welded Joint
A joint welded from both side of a joint.
Groove Weld Size
The joint penetration of a weld size.

For a concave fillet weld, which throat dimensions are the same?
Actual and Effective
In a partial peniteration single V-Groove weld, the dimension measured from the joint root to the weld root is called the?
Root Penetration
The size of a spot weld is determined by its?
In the performance of a vertical position weld, the type of weld progression having a side-to-side motion is called?
Weave Bead Technique
The technique ised to control distortion of a long joint where individual passes are applied in a direction opposite the general progression of welding in the joint is called?
Backstepping
A technique ised in a multiple layer weld deposit where each successive layer is longer than the previous on is called?
