Welding to plate embedded into concrete
Welding to plate embedded into concrete
(OP)
I have ran across the situation in an industrial location where the site engineers insist on welding to embed plates. That is, steel plates embedded into concrete. The site engineers claim that the plates were cast into the concrete for the purpose of using them as weld points at later times. Has anyone ever seen this before? It has always been my understanding that the heat produced in the welding process would be detrimental to the surrounding concrete.
Please advise - Thanks!!

We have specified plenty of connections with continuous 1/4 inch weld with no real problems.
Use the google at the top of the page to look for previous articles on embedded plates as there have been some good threads on this.

I never heard of any concrete issues.

If you produce enough heat to hurt the concrete, you'll be rewarded with a small explosion due to expansion of vapor in the concrete voids. In order to affect the strength of concrete, you would have to maintain a high temperature (>600C) for a period of 3 to 4 hours...this doesn't occur in welding.

Is there anything else that you can use an embed plate for besides welding to it? I suppose you could provide a shop welded connection to it and the whole unit gets cast, but they never set the embed in the right location.
