Damage and Corrosion Diagnostics of Welded Light Alloys Ship Constructions

Abstract:

Applying diagnostics consisting in evaluation of deformation based on corrosion potential measurements it is possible to extend lifetime of technical structures and make them safe for people and environment. Development of anticorrosion techniques and staff training is a fundamental requirement for safe exploitation of technical structures made of 7xxx aluminum alloys. Corrosive marine environment enforces engineers and technicians to implement advanced anticorrosion methods to make life on ship much safer. The paper presents selected problems connected with safety of exploitation of welded constructions made from 7020 and 7020M alloys in marine environment and a new method of corrosion diagnostics. Mechanical properties of the welded joints made from different kinds of binder have been determined. Corrosion resistance of these joints without anticorrosion protection has been investigated in seawater environment.
