    Default The Ten Commandments for Welders

    A little piece I came across, while humorous, there is much truth in the Commandments.

    Heh.

    The grounding thing - I occasionally forget to ground when tigging and get zapped by the high freq. start. Or once or twice I've zapped the filler. I know some people do it as a party trick, dancing the blue sparks to their finger. Too much for me, I reckon.

    What's with the unpurged tank? What does it mean?

    than that we do not like the tone in which it is expressed.”

    I welded on a used propane tank. Didn't matter how much I purged it I never felt relaxed striking that arc

    Blow some shielding gas in it.

    I thought filling with water was the way to go?

    Hydrocarbons get into the small seams of fuel tanks and can reside there a long time. Also, if there is HC in the tank if you fill it with water the HC tends to float on the surface of the water. When you pour the water out some of the HC re-deposits on the inner surfaces of the tank even though a good deal is carried out by the water. Here it is recommended to steam clean the tank prior to any welding operations.

    Exactly, steam, steam and more steam, then preferably work on it while it's still hot.

    Most gas tanks can indeed be thoroughly purged with water.

    If whatever it is, is a gas at room temperature it wont be hanging around in seams and being redeposited on the sides.

    If you think you can still smell gas in a properly purged propane tank...you are not, it is the putrification chemical that hangs arround.
    That stuff is very hard to get rid of.

    Liquid fuel tanks are another thing alltogeter.

    seems these days, people wash em out as well as they can then fill em with argon.

    Sure beats one old method...wash the fuel tank out....then put it on the other side of a brick wall..and reach around the corner with a long match.


    Serioulsy with petrol tanks.
    drain as much fuel as you can
    pour in a generous quantity of metho and slosh around.....the remaining petrol will disolve in the metho.
    drain the metho
    pour in a generaous amount of water and slosh around...the metho will disolve in the water
    drain the water
    refill to the brim with water and drain.

    I'd still be filling with argon and putting masking tape over the openings.

    cheers
    Any thing with sharp teeth eats meat.
    Most powertools have sharp teeth.
    People are made of meat.
    Abrasives can be just as dangerous as a blade.....and 10 times more painfull.

    I still remember the words of a certain battery guru.

    Thou shalt use insulated tools when thou atendest to batteries, lest thou bounce on thy buttocks in an unseeming fashon and earn the derision of thy companions.

    When I was a kid, the radiator workshop would also clean your fuel tank. They would take the tank off the car, empty the petrol in a separate tank, cut an opening in the top side of the tank some 200x150, poor diluted chloridric acid in its and wash it by sticking the hand with a glove inside and rub it thoroughly out. Rinse and oxy weld shut. If you were lucky you may get half of your petrol back ha ha.
