Adler-Etching (Etchant for Testing of Welds)
Adler etch is a ready-to-use solution primarily used for the examination of welds. It is particularly suitable for use on cast iron, high alloy and corrosion resistant steels, as well as aluminum, cobalt and nickel alloys. Its special suitability is to make weld joints and coarse grain visible.
The chemical properties of this solution result from its components: fuming hydrochloric acid, ferric chloride and copper ammonium chloride dissolved in distilled water. The fuming hydrochloric acid and ferric chloride act as strong etchants, while the copper ammonium chloride acts as an oxidizing agent.
The operation of Adler etching is based on the reaction of these strong etchants with the metal surface, exposing the structure of the welds. This process allows for detailed visual inspection and evaluation of the weld quality.
