It appears to be a welding technique referred to as "walking the cup", where you rest the "cup" or your tig torch against the parent metal and move it like moving a heavy barrel (read: drum). This technique is very difficult to master and is very gratifying when you can or when you see someone perform it.
Titanium also changes color this way based on the shielding gas used!
I'm a weld technician, and as an accomplished welder myself; I can assure you the individual who performed this is very skilled.

Real question... Do the pretty colors mean that it was welded properly, do they serve a purpose other than being beautiful?
