    Thanks Guys;
    I'll grind the galvanize off. I am well aware of the dangers of galvanive. In my past life before retirement, one of my jobs was certified OSHA Respirator Instructor. I will be safe, but thanks for shareing the dangers.

    From MSHA:



    "When personal respiratory protection is required, this may be provided by a supplied-air welding hood or when the components and concentration of the fume are known, by a filter-type respirator with filter for protection against fumes. It is preferable, of course, that adequate ventilation be provided so as to make the use of respirators unnecessary."

    Yep, it's just on the surface. Grind it off without breathing it and save some cash!

    and drink a big glass of milk after you finesh. .Just to be safe
    Milk helps neutralize some of the poisons from the Galvanize

    Grind it off, but wear some kind of protection for the nose and lungs. A good 3M half mask respirator works well...Bob

    Welding Galvanized Steel

    I am trying to save a 160 mile round trip to the steel yard. I need (4) 6.0" pieces of 3.0" x 3.0" x .375 angle to be MIG welded into my project. All I have is the proper size but its Galvanized. Any problems if I grind the galvanized off, to bright shiney steel and them MIG her ? Or does the Galvanized penetrate deep into the steel.

    Thanks
