On the basis of chemistry? that hexavalent chromium is formed via oxidation, and I was throwing out basic ways that are used to increase oxidation rates and decrease energy thresholds needed to attack the chromium oxide layers and oxidize the element. "Could potentially" means I was brainstorming possibilites, I didn't look for a study, I'm not too worried about it. I'd be more worried about Nickel than Chromium, but it's obviously false that you "need" welding levels of heat to produce oxidized forms of Chromium.
