Susceptibility to Stress Corrosion Cracking in Hydrogen Sulfide Environment of MAG Welded Joints of API 5L x 65M Thermomechanical Treated Steel

摘要

The paper analyzes the stress corrosion cracking behavior of welded MAG welds in pulsed current of thermomechanical treated API 5L X65M. The results of the corrosion tests in hydrogen sulfide (H2S) environment corroborated with those of the metallographic investigations showed that for the welding conditions established, the pH values and HsS concentration correspond to the international standards imposed, and the metallic continuity defects are absent.
