MS my opinion is mostly from observation and the advice of a few friends who know what there doing, the reason i say to butt weld is that if you overlap you may get moisture or crud in the overlay. my own talents are restricted to some self taught tac welding and a few welds on tubing and patch panels i suppose there are pros and cons for both methods. #20 (permalink) 09-03-2002, 06:55 PM
