It'll be fine.
It's carbon steel pipe. |

Yep, use ER70S-2 or -6 It'll stick just fine. Given the application I would think a 110 volt MIG with gas should be enough.

Yes, spent 7 years welding galvanized for a fence company..but we don't grind it off..just burn it..problem is , are you sure your sign is steel? Also, need good mask for welding galv. Even if you grind it...

Use flux core, it is the correct application here.

...also, as far as the galvanized you should be fine doing it outside. Grind it off and try not to breathe the smoke.

Yeah. Small directional fan blowing into the back of your helmet and away from the weld. Galva is nasty shit. Taste it for days just grinding on it. |

You're over thinking it. Just shield the breeze and weld it. Not like it's load bearing. Hold your breathe if you want. Not welding enough to worry about.

Actual welder here, not a hobbyist.
Spend the $7-10 on a welding fume rated disposable mask. Get a gentle breeze going. Keep your face as far away from those fumes as possible. Weld a bit hotter than normal if you're burning off the zinc. Preferably grind the junk off, but this isn't a critical application. Drink some milk anyway. Look up "welding fume fever", if you don't want to spend the $ on a mask... ETA: did not see ALUMINUM. You're not welding aluminum to steel without explosives. Just go buy some hardware. |

My first reaction is "if you have you ask you probably cant"
Clean off the galvanized and you can weld it just find (make sure you grid it off and dont just scuff it up). (bracket to poll) Aluminum and steel can be welded together, but you wont be able to do it at home. Grinding on galvanizing is almost as bad as welding it. make sure you get a good mask and the right filters if you are going to do a bunch of it. |

Set it up outside in a slight breeze. Ground off the galv.
Stood back far from it and spot welded it on the visible side. Cooked the shit out of it on the back side in small patches. Couldn't knock it off with a hammer. Done. My welds are ugly as fuck (sorry no pics) but it won't fall off and kill someone. Thanks gents. |
