Modeling A Weld Using An Edge Weld Connector

The edge weld connector joins surface bodies together

The edge weld connector extracts load and stress information from the simulation results. The connector uses the information to calculate appropriate weld sizes .

Groove Weld – Single Sided

Groove Weld – Double Sided

Fillet Weld – Single Sided Fillet Weld – Double Sided

Modeling A Weld Using An Edge Weld Connector

The weld calculations uses the throat shear method.

This is based on forces rather than stresses to size the weld.

Currently the edge weld sizes follow the guidelines set forth by the American Welding Society Section D1.1. 5.

The edge weld connector works best for perpendicular weld junctions.
