I like designing and fabricating two stroke exhaust pipes. I think the average amount of welding in a pipe is 4-5metres. Usualy weld on 19Amps 1mm electrode.
Before anyone says "that's fantastic":rolleyesI'm not looking for fanboi approval as there are plenty better than me at this caper.
I wil in the future be looking to fabricate a Ti pipe and would love some input on purging these types of shapes, if anyone has experience with Ti welding
