I have a pipe that comes out of a head perpendicular to the header, a basic T configuration. I am trying to model the weld for that saddle joint. It requires that the end of the pipe have a 45 degree bevel all the way around, starting with the inside face of the pipe and opening toward the outside face of the pipe. I have tried all manner of swept cuts and just can't seem to figure it out. I can't figure out how I might do it with a loft cut. I am still pretty new to Soldiworks. I have attached the 14" pipe part file. In the lower right corner is a sketch of a line showing the cut profile. I realize it is not a closed profile, I am just trying to show the angle/shape of the cut. After the cut, I don't want any material left below the line anywhere around the saddle joint. So the cut needs to follow the inside edge of the pipe.

Once I get the cut, how do I model the actual weld? It is supposed to have the 45 bevel through the pipe wall and then a 3/8 fillet from the outside of the pipe wall down to the O.D. of the header pipe. I assume it would have to be some kind of lofted boss?
