If you want to talk about pressure retaining welds then yes I also do radiography and ultrasound. The visual appearance of a weld has everything to do with its structural integrity. This is a gas tungsten arc weld also known as TIG (tungsten inert gas), you should look for adequate fusion at the toe of the weld beads and porosity. The welds are difficult to see. The photo of the "X" section show welds of less than desirable quality but I highly doubt they will come apart. The prices currently being charged are ridiculous.
The X-pipe posted in the original post is not TIG welded. Only in some small parts it is which matter the least. It is a polished out and smoothed out MIG.

Unfortunately, the hard part is helping people understand that a U.S. made unit, the cost of the high grade stainless steel would cost far more than 400 dollars alone, and this does not reflect the manufacturing costs or any other costs associated with the unit.

There are many members on this forum that can attest to having the cheaper quality x-pipes and what has happened to them after some decent amount of use.
