IP67 enclosures and weld specs 1

[Korichnevijgigant]

Client just dropped a marketing bomb on me and asked that the system be IP67 rated

I have never dealt with IP67 before, any tips?

its a large equipment enclosure and has a structural frame to be fork lifted/craned into place, it also has the electronics along with the equipment, so its basically 16 gage 304SS welded to 1/8 channels

I was just going to stitch weld and come back with a sealant to go over the weld, but I am not confident that will pass an immersion test like IP67

Spot weld with weld through sealant.

@MintJulep
Like the stuff you would put on a car when replacing rusty floorboards??

Interesting, I wonder if that would hold up to the IP67 test

I did not look up the specific submersion time for IP67

3M weatherban - " it will lose most of its adhesion if totally submerged in water for 24 hours. Adhesion loss should not result from occasional wetting or high humidity if properly applied. "

I did not look up the specific submersion time for IP67

Its 1 meter deep from the bottom of the item or 15cm from the top of the item for 30 minutes

I've been pushing back on this ludicrous specsheet engineering since it started, so far this is the only one that is sticking
