Puddle welding deck to galvanized steel
Puddle welding deck to galvanized steel
(OP)
I have always specified Hilti fasteners to attach deck to galvanized beams, but I've been asked if puddle welds could be used instead. My thought that it's harder to puddle weld to galvanized steel than it is to use the Hilti fasteners but the fabricator is telling me otherwise.
Any thought on this would be greatly appreciated.

It's not hard to weld to galvanized beams, but it's 1) not healthy , 2) it gives bad quality welds and 3) it messes up the galvanized beam.
Unless there's more to it, I would strongly advise against...

Stick to your guns. Puddle welds are fine, but you need quality inspection and the welder must be certified for sheet steel in the potential number of layers that can occur at laps (Usually max. of 4 layers)

Ron, you're absolutely correct, that's almost the exact thing he said

They are often used for galvanised deck material and touched up with zinc rich primer, but I've not spec'd them for base material that is HDG... the spatter, fumes and damage to the base material, as noted, are a real problem.

Old timers would also drink lots of milk as this helped settle there stomach from the fumes, I have seen several young welders welding beams to bearings come up puking when it was not well ventilated.
