Partial weld around a pipe joint with clear heat affected zone. This is ASME SA106 Grade B steel pipe NPS 2.5 SCH 80 with J-grooved prepared ends. An automated TIG orbital welder made half an orbit before aborting. The heat affected zone is clearly visible because of the polished ends, even though it is generally innocuous in this material.

Temper Colors
A method of checking temperature is by the temper colors: A given temperature will leave a distinct color corresponding to that temperature on a freshly filed surface. (It should be noted that the presence of alloying elements in the steel affects the colors formed, and some of the higher alloy steels have no temper colors.)
This temperature range is very evident in the picture above, at the outside edge of the temper color you can see the transition of all the colors and corresponding temperatures.

Crop the wall on the sides that isn't necessary. Lightened up the dark ares, but kept colors exactly the same. Reduced jpg file size with no perceivable loss of quality.
