Control the heat during welding – Lower heat during welding can reduce the amount of time impurities have to gather at the grain boundaries. Q: A few months ago, you wrote that 6061 is “hot short.” I’m not familiar with this term. Can you explain it? As molten metal re-solidifies, impurities tend to segregate at the grain boundaries. As such, these locations tend to have a lower melting point than the metal itself. When a molten metal is heated and solidifies, crystals are formed independently of each other. These crystals are distributed throughout the metal and are randomly oriented. These crystals are known as the grains of the solid, and the interfaces between grains are known as grain boundaries. The properties of these grain boundaries heavily influence the overall behavior of solidified metal.

Select the right materials – Steels with low residual phosphorus or sulfur content can minimize the impurities that segregate at the grain boundaries. Three films in, and director Mathew Puccini has pretty much covered the gamut of queer experience. With a light touch and a lyrical eye, Puccini’s shorts play like a moving triptych of quietly pivotal moments in the lives of queer men. “The Mess He Made” starred Max Jenkins as a man waiting for the results of an HIV test, and “Lavender” featured Michael Urie as half of a couple who invite a younger third into their longterm relationship. “Dirty” explores the awkwardness of a more universal folly — bottoming for the first time. As always in Puccini’s work, the characters are tender and natural; the images aglow with intimacy. I find sex to be pretty absurd, and I wanted to show that,” Krantz told Short of the Week, which premiered “Squeegee” in late May. “I’ve also been in relationships with people where we both know there is no practical way to really be together. But when you’re having one of these ‘flings,’ I have found that it can actually be easier to express how wild you are about a person… because you both know that you can never end up together. So that’s the glass between these two characters.” “Ambrosia”

Origin of hot-short

A: Hot short is a standard metallurgical term, but I shouldn’t have assumed that everyone would be familiar with it.
