The welded corner feature in SolidWorks provides a visual representation of a weld, and allows you to get a semi-accurate weight measurement. This also carries over to drawings, and the welds can be shown. To get started, let's take a look at a few examples. In this corner here, I've got a closed corner, corner to corner, butt corner, and I have the open bend region here. You can try closing up the bend region, if you want, but with for thicker materials a lot of the times you'll make the weld feature fail. Or have errors. So in this case, it's open and I'm going to go up to the Sheet Metal, come over here to Corners, and use the welded corner.
I'm going to choose this face here and as soon as I click on that, you can see it fills that in with a representation of what's going to happen when I click on the welded corner. Generally when you are doing welded corners, you want to have your 2 edges very close together like this so you have a butt corner, or even a little bit of an overlap, here. When the weld cools, it doesn't warp your part. Go ahead and click okay. And you can see a nice weld gets filled in there. And I can also do the same thing over here. This has got an open bend region, so this is probably not recommended. But SolidWork can definitely handle it if you do get put in that position.
But before we do this, I want to point out that SolidWorks actually adds that weld, and also adds that material to the weight of the part. So click on evaluate real quick, look at mass properties and you can see this is 3.26 pounds and 11.5 cubic inches. Let's go add the weld come back and weight again. Go to sheet metal, go to corners, go to welded corner and come over here and select this face. You can see that it is going to fill in all of that material and I have a few other options down here, I can change the fill out radius if I wanted to. Either up or down.
You can see that's going to move slightly. You type in 0.125 to get a little bit sharper corner. And I can add some texture, I can add weld symbols if I want to. But in this case I don't really need them. And when I'm happy with that I go ahead click on OK. And there it is. Let's go back and evaluate that again. Weight it and you can see, we add a little bit of mass and we added a little bit of volume. Okay. When you're happy with that you see the two welded corners. Comes out pretty nice. And you've got a finished part. Welded corners can be very helpful in the right situations. And allows the designer to add in some polish to the design. However, they also add in a lot of features and overhead to the part or assembly, and should be used only when necessary.
