    Metal Floor Safety

    Hi guys,

    just got a tig welder and am looking to start welding. Before I do, I have a safety question.


    My space is a relatively small studio with a painted metal floor. Is this floor a conductivity hazard? Should I invest in a rubber mat? Here's a photo of my setup.

    I guess I would say no. As long as you ground to the work item. I would be curious what is under the metal. IE: loose sparks.

    Re: Metal Floor Safety

    First job is to mount the Fire extinguisher by the exit door, or on the welder cart. Then find out what's underneath the metal, if its filled with sawdust, or aluminum powder/millings or shavings, or even oil . Stuff like that can smolder, and burn in a trench or pit. A GFCI breaker might be a consideration if that's some kind of sump pit, and the location might get damp, or flood. If the area is clean and dry, and your going to TIG weld mostly, I wouldn't be that concerned with the metal floor. I would still check what's underneath the plates, one day you might need to stick weld something, and sparks always get everywhere.

    good luck

    We did work in smiliar areas with open butt joints like yours. We laid sheetmetal strips down covering the openings. A self tapping sheetmetal metal in the center of the strip kept it from moving.
    Then laid fire blankets on top.

    Re: Metal Floor Safety

    Thanks for the advice guys! I'm definatly trying to be as safe as possible. I'm on the second floor of an old industrial building in Brooklyn NY. I don't own the space and I just moved in. Not sure how I would remove the floor to check on what lies underneath as it seems preety firmly secured. I can definitely cover the gaps with sheet metal and mount the extinguisher close to the exit. I'm going to try to do any stick welding outside so I'm not too worried about that. I did want to do some grinding tho, and of course that's going to produce tons of sparks.
    The place seems relatively dry and without particles that could be kindling.

    I also am realizing that some of the floor is not metal. a few strips seem to be plywood. Would fireblankets be good for covering these as well? Thanks so much for your insights guys. I only did welding in school so this is my first time setting up my own space.

    We fabricated and stick welded pipe on a gym floor. Laid down plywood, then masonite, staggering the seams . Then duct tapped the seams. Covered the welding area with fire blankets.

    A blanket , or a piece of 24 ga sheet metal (duct work) would work well. Maybe duct tape for the gaps in the floor ? Next thing you might look into is a bigger argon bottle .

    Good luck !
