I've seen splits like that on lots of tubing.. its usually how hot the seam welder is set it that causes it to split but it normally will only happen after the tubing has been bent

most places that use welded seam tube will bend it with the seam to the inside of the bend. The lack of stretching the seam helps it not tear
thats one of those situations where you cant win,if the weld is harder than it should the pipe will have weird wrinkles or wont compress as it should and will therefore stretch the outside radius to much and split from that instead. strange things happen..

Correct.. if the weld is right you can put that seam anywhere and it'll bend perfectly

absolutely correct,just a shame its so darn difficult and expensive finding tubing with good welds these days. 10 years ago any tubing would be good for most anything you could imagine doing to it and then some,these days there is all sorts of isues even doing the simplest of things. almost glad im not working with that anymore

I was doing the buying for all the material needed for the exhaust lab at Chrysler and I bought all of my tubing from a couple of places(both were US made tubing) and I bought about 3000' per year.. only once did I have a issue with bending it and it split at the seam.. plus old tubing gets brittle from just sitting around... almost all of what I bought was 416 stainless tubing unless we had a special build for someone that called for another material.. the 416 is a stainless but is magnetic but has real good bending properties
