Resumen

RODRIGUEZ-PEREZ, Manuel et al. Evaluation of different types of varnishs to protect underwater welding electrodes. Ingeniería Mecánica [online]. 2012, vol.15, n.2, pp.95-104. ISSN 1815-5944.

The article aims to assess the potential use of different types of paints and waterproofing materials for the electrodes of type AWS E 6013, when performing underwater welding in wet conditions. The coatings evaluated are Vinyl, Maritime, polyurethane base and a new variant Isopor base. Evaluation methods include the behavior of the mechanical strength to the coating gives each of the varnishes, the adsorbed water and the type of structure in the welds, using conventional microscopy. In this sense, the structure in all the welds made with the electrode E 6013, regardless of waterproofed used is similar, characterized by primary or ferrite grain boundary and Widmanstätten type, however, it was determined that the base waterproofing Isopor, guarantees better protection of the electrode in terms of the amount of adsorbed water and coating adhesion.

Palabras clave : underwater welding; waterproofed; electrode.
