Part of my Remit, back when, was to check the quality of weld samples, witness testing, certify results, and issue certification to welders working on Gas and Oil lines for the North Sea Fieids, Shipyards and Boiler Makers and Repairers. I knew all the codes and methods, X-ray`d samples etc; BUT my own welds are still "a lot to be desired". I can lay pidgeon poop with the best. Welding is 20% knowledge and 80% practice, practice...................đ. I had a great deal of respect for those pipe line guys, they performed in conditions many would balk at. They mechanised it in the later stages.
I fabricated a new shell for an American R-V silencer, using the old internals. lasted over 5 years. Then I replaced it with a Stainless One custom made by a Company Near Bolton, ÂŖ300 just for the silencer, ÂŖ200 cheaper that getting one from the USA!!..
