Dropping in a couple of photos of basic sheet metal finishing. Excuse the bad quality as i am new to posting, any tips are welcome!
First one is a 0.7mm corner joint, length 180mm, notice the difference in the coloration even though a standard number 8 cup was used for all of those welds.
Thin sheet metal is extremely sensitive to travel speed, first one was welded the "Proper way" and is completely silver, second one a bit slower on purpose to demonstrate it.

This is an open corner joint with a butt weld on the side, material thickness 1.2mm which makes it very workable.

Lastly a big tray, measuring about 2.1 meters long (7 feet) that had lots of different joints to grind. Notice the inside corner joint which has full penetration yet is completely white in colour, we use a nitrogen back purge for joints that would be difficult to grind and finish such as inside corner joints, the end result is perfect.
