Fillet Weld
|
A triangular weld that joins two metal parts at a right angle. All fillet welds defined in the Edge Weld PropertyManager have a 450 configuration.
|
|
Groove Weld
|
A weld applied in a preformed opening or groove between two metal parts. Groove welds defined in the Edge Weld PropertyManager can represent all edge-to-edge weld types (square butt, V, J, & U conditions).
|
|
Local Weld Joint Coordinate System
|
Edge weld results are calculated for all mesh nodes on the intersecting edge of the terminated part. Results are calculated with respect to a local coordinate system established at each node as shown in the figure. 
- Surface Normal, Us: Axis is normal to the top surface of the shell of the terminated part .
- Weld Joint Normal, Uj: Axis is normal to the intersecting shell edge of the terminated part and oriented away from the part.
- Weld Axis, Uw: Axis runs parallel to the direction of the weld seam. Its direction is defined by Uw = Us x Uj.

|
Weld Size
|
The dimension of the joint penetration of a groove weld (s). The distance from the root to the toe of a fillet weld (weld leg).
|
|
Weld Throat
|
The minimum distance from the root of the weld to the face of the weld (t). 
|
|
Joint Normal Force
|
A component of the weld force (Tj) acting normal to the intersecting shell edge of the terminated part along the weld joint normal axis, Uj. Units given in force / unit weld length.
|
|
Shear Weld Axis Force
|
A component of the weld force (Tw) acting parallel to the weld seam along the local weld axis, Uw. Units given in force / unit weld length.
|
|
Shear Surface Normal Force
|
A component of the weld force (Ts) acting along the local surface normal axis, Us. Units given in force / unit weld length.
|
|
Bending Moment
|
A moment (Mw) acting about the local weld axis, Uw. Units given in moment / unit weld length.
