INSTALLATION OF PREFABRICATED CONCRETE AND CONCRETE CONSTRUCTIONS 8.Welding and anti-corrosion coating of embedded and connecting products

Welding of embedded and connecting products should be carried out in accordance with sect. 8 SNiP 3.03.01-87 "Bearing and enclosing structures."
Anticorrosion coating of welded joints, as well as sections of embedded parts and connections should be performed in all places where the factory coating is broken during installation and welding. The method of anti-corrosion protection and the thickness of the applied layer should be specified in the project.
Immediately prior to the application of anti-corrosion coatings, the protected surfaces of embedded products, ties and welded joints should be cleaned from welding slag residues, metal splashes, fats and other contaminants.
In the process of applying anti-corrosion coatings, it is necessary to especially ensure that the corners and sharp edges of the products are covered with a protective layer.
The quality of anti-corrosion coatings should be checked in accordance with the requirements of SNiP 3.04.03-85.
Data on the anticorrosion protection of compounds should be drawn up by acts of examination of hidden works.
