please help me out with this.... I just need to do a simple pipe which is spirally welded.... I'm a newbie and from what I read so far and tried that weldment need at least 2 bodies attach and then weld them together but in my case, the pipe is a single body.... I manage to make the pipe being cut spirally using the sweep feature but I cant weld the part.... this below is the zoomed picture of the sweep cut profile......
