I do not believe you can model welds inside a single part, apparently SW do not realize that sometimes you need to use welding on a single part, which is a real need sometimes.
from SW2008 or SW2009, exist the command 'Welded Corner'.
The Welded Corner PropertyManager allows you to add a weld bead to the corners of a folded sheet metal part, including miter flanges, edge flanges, and closed corners.
The problems with welds at this time with SW are:
1.- They colapse the model... as you add welds the assembly performace gets slow and slow.
2.- One of the objectives of placing welds into a CAD model is to obtain data for the manufacturing process (i.e: material required for the welds, lenght and number of welds, to calculate time, or to be bale to program welding robots using the C/L of the weld and the type of weld, etc. None of this can be done (as far as I know) with SW.
Placing welds just for visual effect on a render is nice, but a CAD is more that a rendering tool, in fact to produce great renders you can get tools way better that SW.
For drawing purposes we use welding symbols where we need welds (and we use a lot)
I totally agree with you in regard to weld beads in SolidWorks. They are there to make your model look nice and serve no other purpose.
In Inventor after making Weld beads you had the option of exporting these welds to an Excel spreadsheet.
The info that was automatically generated was weld size, weld length, volume etc.
From these you could work out total weld lengths added up weight due to welds and also do a costing exercise ie how much Mig wire / welding rods are needed to weld the assembly,
SolidWorks at the moment is sadly lacking in this department.
May as well do as you do and detail welds on the drg.
Mark (SolidWorks 2009 SP4.1)
say '...With the introduction of multi-bodies in SW2010' is not corret.
Multi-bodies were born in SW2003.
Excuse my accuracy, but the forum (in reading) is accessible to all ... not a time ago you need to log in to view it, and then, for those, who are fasting to SW, may misinterpret your information.
Multi-body parts are nothing new this is true, but SW2010 has for the first time added the ability to create multi-body sheet metal parts. Something we were previously unable to achieve. From what I've used of it, a very handy feature indeed.
we must stay on topic and answer to the question. SolidWorks 2010 isn't yet official and I don't recommend even if it were in SP0.0 and it isn't the support for multi-sheet metal that solves his problem.
If the tank is made by deforming, certainly he didn't use sheet metal tools, because SolidWorks doesn't support the flattening parts of sheet metal obtained by deforming.
If it's a folded sheet metal .. he can use the command I recommended.
If it is a multi-body, of which the main piece is a sheet metal, he can use the command in the weldment toolbar.
SolidWorks doesn't support formed parts.
If you project formed parts, they can't be unfolded and surely you have not used sheet metal tool.
If you project your tank with sheet metal tool, you can use Welded Corner.
99% of our work is done using the sheet metal module... however the welds in SW are totally useless, since all they do is to add a visual weld for a more realistic rendering of the 3D object, however from the point of view of engineering they are of not use, for example:
- If you add welds all you add is more load to the model
- Adding welds without specifying the material properties are of no use on performing structural analysis.
- Welds in SW do not provide any information such as: number of welds, length, volume, etc. that can be use to estimate time and cost of the process.
- You add welds but the information can not be use to extract data to program robotic welding.
Is any use for welds, other that to see the filet on the 3D solid (at the expense of machine performance)?
And believe me, we know to use the SW sheet metal functionality at 100% of his capability (and sometimes more).
The point Mauricio and myself were making was that although it is possible to add weld beads in your model, why bother for the reasons already stated.
It takes up resources, slows down model, and you cannot use these weld to get any info from.
Detail welds in drawing. Look at how you model in something like X-Steel (the industrial standard package for structural steel work) you do not show weld beads or butt welds within the model, you show weld symbols in the fabrication drawing.
Now if you could extract information from the weld bead similar to how you can in AutoDesk Inventor, in certain circumstances it might be beneficial to add these welds, for reasons already discussed.
You can model the welds without any special tools, i.e. extrude, revolve, sweep would be the most popular methods.
Uncheck the "merge result" in feature dialog box when creating welds, this will give better control over display.
the weld thing is the same as the making threads on a model....subjective!
some want, some don't and some don't give a hoot either way.
but there have been some great suggestions on how to aproach this issue?
