| Interesting Picture Carsten! I see how good your welds look and still they are not perfect.  I understand that is why you always test.  Flaws can happen for anyone.  I can weld farm equipment and get it to hold together, but I think when it comes to welding my hull, I will have a pressure vessel certified welder do the job.  (Maybe I can lower the cost some by offering him beer at the END of the day, or better yet, promise him the first ride in the sub.)  Great incentive to do a good job!
