Food-safe permanent repair (re-join them) of 2 tines of metal (stainless steel?) whisk/beater of electric stand-mixer? Answered

I have a 34 year old stand mixer (Sunbeam Mixmaster) which uses 2 separate beaters (whisks) to mix ingredients in a bowl while it rotates. The beaters each have 4 tines which are joined with a rivet where they intersect at the tip of the beater/whisk (see photos. The broken beater is the one on the right).  On one of the beaters two of the tines have come apart (broken) at the rivet so I can't re-rivet to repair.  I believe the metal is steel (maybe stainless although there is some rust on the metal - they ARE 34 years old).  What can I do to permanently re-attach the broken tines at the tip, that is food-safe and doesn't add bulk to that spot? (the beaters interlock with each other while rotating so they have to be the same height or else they won't interlock correctly while spinning).  The mixer works fine otherwise and I am reluctant to buy a new one because the comparable ones that are available are built much more cheaply than this one was (very flimsy, lots of plastic instead of solid metal body) and I don't want to buy an expensive, large and bulky Kitchenaid-type mixer which is more than I need for the amount of baking that I do.  Thanks for any suggestions!


Silver solder.

Brazing would also do.

Stainless steel TIG weld.

Clean off all flux before using.

+1 for the silver solder. They use it for fixing band saw blades. A material that can hold a band of steel together while it rotates around and cuts should have no problem with what you have. But you might need to have some one do it for you.

Also Silver solder is used for jewelry so it is safe for people. In fact the best place to get it repaired might be a jewelry shop.

Thank you for replying. Are all these processes food safe?

Yes, easiest diy would be the silver solder using a plumbers blowtorch(MAP gas)

Cheapest would be brazing with a normal blowtorch using propane gas, a fine flame point would make it easier.

Best would be TIG weld using ss filler wire at a pro weld shop.

If it is stainless steel than have it tig welded with stinless steel - same material causes no problems once cleaned properly.
Brazing can cause corrosion if normal steel or brass is used.
If you get them fixed ask to have both fixed so there will be a little bump in the center, this way you should have a few more years of usage.

Maybe soldering, Just make sure that you use solder that does not contain Lead

TIG weld. Ask the local car body shop.
