Ah, so that's what this is all about, tempering vs. annealing. I have a difficult time following all the quote snippets that you use in your responses. The two terms are often used interchangeably, but you are correct that technically there is a difference. Annealing is heating the steel above critical temperature and slowly cooling it, tempering is heating the steel under critical temper. To clarify, I anneal the weld after welding to remove any hardness generated by the welding process and temper it after grinding to increase toughness. My point is, or was that a post heating process of some sort improves the durability of the weld on a bandsaw blade and whether annealing is better or tempering is better seems to be up for debate.
