For something to "lose" it's temper, it needs to be heat treated and quenched to a specific "temper" in the first place.Also, the guy who will be doing the welding, in my second hand conversations with him, has expressed concern about the frame "losing its temper" and said it may need some kind of treatment after welding? I'm not sure what exactly that means or if its something to even be concerned about as I haven't seen any mention on here about doing some kind of treatment after welding on a hardtail. He said he has zero experience with welding motorcycle frames so he isn't sure if that's concerning either. He was a union welder so he can weld, he just never did a motorcycle frame before. Any input here would be helpful too.
If you think it through logically... anytime a frame gets damaged and needs welding... even welding up a small 1" crack... you'd have to disassemble the entire bike, strip the paint off, put it in an oven, heat it to cherry red then quench it to whatever "temper" the factory calls for. Then it's back to paint and reassembly.
That's a long way of saying no, frames aren't heat treated. They use normalized mild steel tubing. Call it "weld and forget."
