Am thinking of shorting my M2 frame. Just want to cut off the very rear portion and possible weld back on the round end. Anything special needed. It is crome molly? will a stick welder work or would a mig be better? | ||

Ewww don't use a stick welder on it! Mig is better but TIG is the best! And yes it is chrome molly  Jodie | ||

If you have to ask whether you can weld a particular metal with a given process....the answer is always "No". | ||

Gas rules! (cause it's all I got...) Maybe you can find an old junk frame to do a test on. Cut a chunk off, weld it up, and pound it in a vise until it fails. If it failes at the weld, start over.... | ||

Welding tubes good is the hardest, but it won't be supporting any real weight, maybe the taillight at most. | ||

With high carbon steel tubing, as is typically used on motorcycle frames, hydrogen embrittlement at and along the point of weld (the heat Affected Zone or HAZ) is an issue. If it is welded with a TIG welder and the welded area (or entire frame) is not annealed after welding, it can crack along the weld pretty easily. But a convenient side affect of using gas welding is that the welds may not need any further annealing after the welding. That is because the gas welding process generates a lot more heat than TIG welding and a much larger area of metal is heated to or near the welding temperature. This eliminates the hydrogen embrittlement along a narrow HAZ. And a gas welding rig lends itself to the use of some pre-heating and and gradual cooling of the finished weld than a TIG or MIG unit does. That can contribute to better welds in chrome moly tubing. Welding, preheating, annealing, etc., can be sort of controversial topics amongst welders. There are many opinions and schools of thought as to the "right way" to do it. I'm not an expert welder, but have done a smattering of it. I've probably spent more time reading about it and agonizing over what to do than I have spent actually doing it. Jack | ||

Thanks for the info. Think I will get some estimates from some pro's first. Would like it to look good. |
