Hi
Nice to hear Jody. Reason why I have used s6 is that on heat transfer pipes (S235) s2 leaves weld pool really dirty. Even after cleaning of that mill scale from inside and outside of the pipe. Gonna take some pics next week and post on here. I could also do some test joints and check them with microscope at the school, just for curiousity
Comments & questions on new & past videos
It seemed pretty obvious to me what Jody was doing with the hammer. Plus, the real frames are gas-purged, that point was made several times.

I was an avid mountain biker but we moved and the closest trail is 30 minutes away; I was 5 minutes from the trails. A lot of people are building their own bike frames using lugs, propane torch, and brazing rods. Bikes take a good bit of abuse especially mountain bikes. Considering the thickness of the tubing that was welded the sledge hammer test was impressive. High end factory bikes are notorious for breaking welds all the time. Building bikes is something I would like to do as a hobby, but it's more difficult than it sounds.Nils wrote:It seemed pretty obvious to me what Jody was doing with the hammer.

Welcome,
As I said I like the hammer test. It shows if you are on the right track. If you want to build bikes, even as a hobby, go for it. Being a biker yourself , you know what is availible, know what people offer. You could build a couple and ask people to ride the hell out of them for a while, and see if anything needs changing. And go from there.

hahaha love the part where you beat the frame with a hammer
but question - did you do this vid before you wrote your bit on welding certification or did you write it first and then decide to give it a go?
random question.
Peter.
"Even for the guys that welded the bicycle you bought at Wal-Mart. (btw… Walmart sucks). Welding certification testing should not always have to be a complicated process. For instance, the welder who welds the Wal-Mart bikes maybe makes a couple of welds under direct supervision of a qualified welding inspector. Then the frame is taken out back and has the shit beat out of it with a sledge hammer.
What better test for a Wal-Mart bike? "
