Looks like I am the first to dive into the pool here. Sammy, your post seem to always light up this forum :-). I have seen the documents. There are some errors in it but the document is already signed by some people. What is your purpose of posting this here? I can only make two guesses. The first being your concern that these papers are not being properly documented and you have some doubts about the professionalism of the people who signed the documents off. You may have had experiences where Inspectors or clients have rejected the documents and thrown it back to you. Whatever the situation is, you have to understand that the responsibility isn't yours to bear. It lies with the people who signed off the documents. If there are mistakes in the documents, someone else made those mistakes. Not you. You need not have to feel sorry or bear the thought that if you had been more vigilant, you could have saved some embarrassing situations. Your genuine concern for the well being of your company must be commended but there is a limit to what you can do considering that you are not a professional in this line of work.

The other guess is, you find this sort of work interesting. You are fascinated by its technical aspects. Perhaps, something you feel you could grasp if you could find out more. This too is to be commended and encouraged. But you can't find out nearly enough by just asking questions in these forums. My advice is to seek some kind of formal instruction. You can do this part time, while still holding on to your current work. A great resource would be here; http://www.weldacademy.com/  Good luck and oh, do continue to hang out here. I am sure the gals and guys here have a lot to talk about your postings ;-).
