Creating Weld on pipe with Weld-o-let

Anonymous — Tue, 15 Jan 2019 00:24:52 GMT

Hi guys,

I am trying to create weld in Inventor assembly and didn't have a good luck so far. I need this weld as solid part to run non-linear static analysis.

I tried Welds options but it failed due to nature of the geometry.

Then I tried using sketch the weld with projected geometry and using 3D sketch as a path but then having a interference.

Please see attached all parts.

Can you please help me!

Thanks & regards,

Generating a proper weld for a weldolet is something I run into on a frequent basis. There may be better solutions out there but what has worked for me is this:

On the trunk pipe:

- Generate a sketch for the connection desired, including a point for drilling a hole and a circle for the OD of the weld. (One may alternately use a circle for the "hole" if no penetration of the trunk is desired.)

- Create the hole using the Center point method, selecting the point from the sketch.

- Share the sketch, if consumed.

- Extrude the circle as a surface, not a solid, such that it intersects the trunk pipe's outer surface at the desired location. Assuming only one weldolet is being attached, do not extrude right through to the other side. (Kinda depends how you set up your sketch plane. If you're working from the center of the pipe outwards, you should be fine.)

- Split the trunk's surface using the extruded surface as the cutting tool. (If you are not drilling the hole, use this same technique for the ID of the weld.)

In the assembly:

- Assemble as usual.

- Generate a groove weld, selecting the bottom side cone of the weldolet as one surface and the "cut" surface on the trunk pipe as the other surface. Check both "full surface" tick boxes. (This should generate a preview of the weld without the need for a weld direction or a Radial option.) If the weld does not preview, switch the order of surface selection. (Yeah, it shouldn't matter and yet occasionally it does.)

Have you created a weldment assembly environment?

Constantly. Or did you mean to reply to the original post?

@leowarren34

YEs in Weld environment.

@leowarren34

fillet weld between weld-o-let and pipe.

In Weld Environment, it dose not accept surfaces.
