Korrosionsverhalten von Anschweißankern aus nichtrostendem Stahl bei hinterlüfteten Außenwandbekleidungen aus Naturwerkstein

Corrosion behaviour of stainless steel weld-on anchors of claddings for external walls ventilated at the rear and made of natural stone.

In the contribution considerations are made about the corrosion of stainless steel weld-on anchors of the material No. 1.4571 of claddings for external walls ventilated at the rear. Furthermore, results of corrosiontechnical investigations on such anchors of buildings which are up to 23 years old are reported. With proper interpretation of the shown connections it must necessarily be concluded that the measures in the set of rules concerning the removal of temper colours and the closing of crevices of atmospherically exposed weld-on anchors are technically not founded and unnecessary from the corrosion point of view if ventilated facades are taken into consideration.
