    Under AS1554, 6010, 6011, 6012 and 6013 electrodes all meet the requirements for structural welds on everything up to and including Grade 300 steel.
    While they have improved dramatically, Low Hydro's are still more difficult to run well for many people and they will get better results by using electrodes that they are familiar with, provided that electrode can meet the requirements of the job, which these can, as has been demonstrated.
    I would probably use 16TC or Kobe LB 52's myself as I like the way they run, but standard rutile electrodes are more than adequate for the task.
    ha,ha, ok,but we are going to have to agree to disagree. i,ve had a few bourbons , so i,ll be direct.
    i,ve tigged up stacks of pipe , but not much stick, but what you say "flies in the face" of traditional stick welding training. i don,t believe for a minute that the fill is done with 6010, and any good welder is happy to run a low hydrogen rod. but it doesn,t matter what i say, its the welding procedure that is done by welding engineers is that what is strictly followed. these are critical welds. you can quote all numbers but the welding engineer is the man, and we must do what is required.
    i think i said i worked with structural steel, buildings, bridges, tanks etc.. structural steel is all migged up, and thats low hydrogen. only site mods and tricky spots require a stick welder. , structural steel we mainly worked with is 350 grade.

    I know 16TC's are bloody expensive. I recently paid $90 for 5kg of 3.2's and they are not low hydrogen unless they are kept in an oven once opened.
    Gold, the colour of choice for the discerning person.

    To be fair this is the same for any electrode stored out of its original packaging out in the wild. Proper electrode care should be part of any meaningful weld procedure.

    The good low hydrogen rods come in a sealed ring-pull can or a vac sealed pouch.
    16TCs are in a very mediocre plastic wrap which is held together with hopes and dreams... not the best for resisting moisture ingress IMO.
