At what temperatures is there no scale and oxidizing fire question!
Hi if I could ask a question.
I would like to know if one could close the gap between two pieces that are to be forge welded. (see axe picture ). My aim would be to get it up to a heat where no scale yet exists. If there is such a thing. Then I would let the piece cool down and add another round of WD40 or equivalent to the welding area in prep for the second heat to do the weld. What are the temperatures when scale starts to form and when there is none. Would there then be any soot from

I went for leaf spring in the end as it is one solid piece and I have had some experience with heat treating it. Making sure I had some boric acid on hand encase the hole thing did not work though. It might be also important to mention that the bolt
