Welding filler rod selection?
So far well happy with a lot of the frame building information. As far as filler rod is concerned, I plan to tack the frame from start to complete frame on jig then do all final with tig welding.
Now my question is which filler rod for cold drawn seamless? 3/8 wall thickness 1.5 od, reason asking as all know for roll cages etc some degree of flex required to avoid stress cracks. Does the same apply for bikes?
