workbench for multilayer weld paths - weldslicer
Posted: Thu Jun 16, 2022 6:02 am
Hello,
I have been working quite a while on something similar to a slicer for 3d printing but for variable multilayer welds. I am roughly following what is described in the literature "equal area assumption". In short along a basecurve the weld get sliced into crosssections, this crosssection get sliced into passes, this passes get connected and return the paths, which the weld torch is going to follow. A scan (either a .stl or a point cloud) of the part geometry can be provided, since the cad based basecurve and the top cover face of the weld (top bead) are fitted to the scan and the slicing is carried out on this adapted model.
A chart of such a weld looks like:
Along the weld (x-axis) the cross section (y-axis) varies. The colored fields represent the areas of the weld paths. Each area is within the weld procedure specifications determined Amin/Amax borders (caused by min/max. weld speed).
This chart looks in 3d like this: Some examples (Input and Output) are found on:
https://www.weldslicer.com/examples
With the provided workbench at https://www.weldslicer.com/examples you are able to see and simulate the generated paths. Also the workbench is used to generate the input data for the weldslicer itself.
The handling of the workbench and the result of the weldslicer can be seen on following youtube videos:

If someone out there is interested and has access to a welding robot please send me a PM.
