In my file Structural Member is turned, in the video this is not the case. I can go and adjust Rotation Angle in the PM to get a proper alignment but I wish to know the reason.
Are the two profiles sketch points identical. It is hard to tell because your first picture is a different angle from the second picture. Just a thought...
I have found it. If you change creating Structural Member order you can get rid of twist, I do not know the reason.
Weldment tutorials will show you the "why". Along with a good workbook on weldments in solidworks.
Every weld profile sketch chosen and every construction sketch chosen play together a certain way. If you choose to start a weldment on an angular line for you base profile pick, it will get the main weldment profile twisted to whatever degree your construction line is.
This is shown by you selecting the vertical member up as your first position for your weld profile. The twist is gone because you have a native static control on the weld profile. It is in position to all three main planes. When you start a weld profile on an angle Solidworks does not know what your actual orientation is, so it tries to make the profile relevant to the line you are starting your weld extrusions on. If you start a weld profile on a line that is 22 degrees angular to any of the planes, it is pretty good odds your welded tube will be rotated 22(The profile "twist" usually matches the angle used).
This is also an issue depending on how your weld profiles were created as well.
