Cast dairy metal

admin

I was wondering if anyone has ever welded cast dairy metal back together?  If you have, what did you use to weld it with as far as filler metal.  I am running into issues at work with these cast clamping pieces breaking.  The lead time to get new ones is 6 weeks if our procurement gets the order in a.s.a.p. The pieces are 2" thick and 4" wide by 6" long and look something like a c-clamp.  Any advice is welcome.    Thanks, Paul

Reply:Wow!! That says a mouthfull.  Thank you for the reply.  I guess it's time to look at different material options for these parts.
Reply:What do you have a batch freezer repair or something?  If you're repairing dairy metal that's in direct contact with human  food, I'd avoid the project all together.  Unless it's a dairy metal appliance made within about the past 10-15 years, there's too much lead in the cast metal.  IIRC, old cast dairy metal is around 4-5% lead.
