- [Instructor] The welded corner feature
inside of Solidworks allows you
to get a nice visual representation
of what your part will look like
once a sheet metal part has been welded,
and it also updates the mass property and volume
of the part, so you can get an accurate representation
of the final volume and mass of your part.
Let's go ahead and show you how that works.
So come up here to sheet metal,
come over here to corners,
and come down to welded corner.
Now, corners to weld,
let's go ahead and choose one of these surfaces.
Now if you choose this surface here it might not work,
but if you choose this surface over here,
it automatically just creates a welded corner here.
And notice this fillet looks pretty small,
so you might wanna increase that
to, maybe like, a quarter inch.
And you can see here, you get a nice round fillet.
It's gonna fill in that entire space
and this open bend region down here at the bottom.
Generally, it's a good idea to leave
those regions, or those corners, open,
and let the weld fill 'em in.
It's gonna make Solidworks do a little bit easier,
or better, job of trying to solve this.
Sometimes, when you do actually close that corner
and fill in that bend region before you do the weld,
it causes some issues.
So, I generally recommend leaving that bend region open.
Go ahead and click on okay,
and there's our new welded corner.
Alright, same thing over here.
Let's try another one,
and come over here to this surface here.
Same thing, because it's a big gap starting off with,
that's generally a bad idea to weld.
You wanna bring those two edges
very close together, prior to welding.
But, Solidworks doesn't really care.
So, if you wanna try to weld this,
it will allow you to put a weld bead here.
It'll actually extend this material over for the weld bead.
Click on okay and there's our new welded corner.
Now, I do wanna point out that the material properties
do get updated, like I talked about earlier.
So, go ahead and get outta this here,
and let's weigh the part.
So, let's roll the history bar back
before those two welded corners,
and come up here to evaluate and click on mass properties.
So, you can see here, the mass is 3.2 pounds
and the volume is 11.37 cubic inches.
Let's go back and then add those features.
There's the welds and let's weigh it again.
And notice, the weight did go up, just by a little bit,
and so did the volume.
So, you can see those are being updated
when you're adding in that weld feature to your part.
The welded corner feature inside of Solidworks Sheet Metal
is a great visual representation of what's gonna happen
to your part once it's welded,
but keep in mind, in the real world,
you wanna generally bring those corners
very close together, prior to welding,
so you don't get too much distortion
in your part, in the real world.
