There are two types of edge welds in SOLIDWORKS simulation: Fillet Weld and Groove Weld. Each weld type can be single-sided or double-sided. Fillet weld is a triangular weld that joints two metal parts at a right angle. Whereas, groove weld is applied in a preformed opening or groove. 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.
Weld size is demonstrated in the following image. For fillet weld, the weld size is the distance from the root to its toe and weld throat is the minimum distance from the root of the weld to the face of the weld. For groove weld, the weld size is the width of the weld coverage and weld throat is the depth of the groove filled with weld.
The edge weld connector estimates the appropriate size of a weld needed to attach two metal components. The program calculates the appropriate weld size at each mesh node location along the weld seam. Select American or European Welding Standards to perform the weld calculations.
Estimate Weld Size Example
Consider a cantilever beam with four edge welds at the fixed end of it. Notice that the beam is modeled using surface bodies to allow adding edge welds. At least one of the two sides of the edge weld has to be surface body to work.
After the simulation is done, to estimate the welds size, right-click on on Results folder and Select “Define Weld Check Plot…”
The simulation is run with an estimate weld size value. However, it seems that all four edge welds fail. Therefore, we will increase the estimated value for edge weld and run the simulation again.
By changing the estimated weld size to a higher number, the weld check plot will show all edge fillet sizes are good now.
Clicking on “Details…” button on Weld Check Plot opens up the Edge Weld Results page which summarizes all results for the weld in this model. Also by clicking on the graph button, a graph of weld size and throat size shows up. See below:
