Edge Weld Definitions

This topic defines some of the terms associated with the Edge Weld connector.

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.
