Welding Cracked Bike Frame. TIG welded joints are the most common type today found on lots of bikes and lots of styles. You can weld titanium but you need an inert gas shield to prevent O2 N2 absorption while the material cools.
What youre seeing is raw steel tubing with a clear gloss powder coat. They did it for 200 and he had to strip the bike to a bare rolling frame and reassemble it all himself. Other repairs to steel frames include.
I have been offered a replacement frame under warranty for my cracked 2011 314 zesty.
How do I choose which welding method to use for my bike frame. Seam crack titanium comes in sheets that are bent into tubes and seam welded Stress crack. I drill clamp a cracked headset tube in my 6000 series aluminum MTB frame as an alternative to TIG welding and expensive heat treating. Very few aluminium frames are heat treated after welding these days and if its a 7000 series its Impractical to do that and so never done.
