Re: [PSUBS-MAILIST] hull material

["Paul Suds" <paul_suds@hotmail.com>]

If I was going to use steel for my sub, I would learn how to weld (I know 
how). There are some evening classes available in most towns and it would be 
very rewarding for you to take a class. The major benefit is that you can be 
flexible with your design and if you ever have to add something or repair 
something, you can do it yourself. In some advanced welding classes you can 
become certified to various standards. Many of the welders currently out 
there know very little about metalurgy, heat treatment, and various welding 
standards. In fact, many welders have had no technical or classroom training 
at all. That isn't to say that there aren't some very good welders out there 
that have had no training. My experience though,  is that if you get someone 
who is qualified to do code work, the weld is usually better than the 
surrounding material. If you can find a good union pipefitter/welder, who 
will do the work on the side, it will be worth the effort in finding one. Be 
careful who you let weld on your rig....Suds
