They don't know shit about welding, cause they don't do a bunch. Canada is actually leading the world atm, with their huge infrastructure and energy projects. 6013 is too slow, and isn't even low hi for the decreased speed. 7018 is loved by engineers, and they have a point because of less cracking and skill levels. But cellulose rods are still used for tons and tons of highly critical xray welds done in the worst imaginable environments, at increased speeds. Good job getting it done Stephen, and now you have some more skills to work on. Don't worry, like anything else worthwhile, it only takes a lifetime! You'll get it, i know you will. And absolutely zero shame in using what you got, that's usually all i use.
